WEBVTT - What are the different ways you can print without wires?

0:00:00.320 --> 0:00:02.880
<v Speaker 1>Brought to you by the reinvented two thousand twelve camera.

0:00:03.240 --> 0:00:08.760
<v Speaker 1>It's ready. Are you get in touch with technology? With

0:00:08.920 --> 0:00:12.240
<v Speaker 1>tech stuff from how stuff Works dot com, brought to

0:00:12.280 --> 0:00:18.479
<v Speaker 1>you by HP Live Wirelessly, Prick Wirelessly. Hi there, and

0:00:18.520 --> 0:00:21.439
<v Speaker 1>welcome to the podcast. My name's Jonathan Strickland. I'm a

0:00:21.440 --> 0:00:23.520
<v Speaker 1>staff writer here at How Stuff Works. And with me

0:00:23.720 --> 0:00:29.320
<v Speaker 1>is my favorite editor, Chris Polette. How's it going, High

0:00:29.400 --> 0:00:31.240
<v Speaker 1>Energy Pillette is what we call him around here in

0:00:31.280 --> 0:00:33.920
<v Speaker 1>the office. Well, today, Plett and I are going to

0:00:34.000 --> 0:00:38.120
<v Speaker 1>talk to you a little bit about wireless printing. Yeah. Actually,

0:00:38.479 --> 0:00:41.440
<v Speaker 1>it's been sort of a thing in our house lately.

0:00:41.440 --> 0:00:42.960
<v Speaker 1>We've been trying to find a way to hook up

0:00:42.960 --> 0:00:45.560
<v Speaker 1>this really old PC that I have. It's the only

0:00:45.760 --> 0:00:48.320
<v Speaker 1>Windows computer I've got, but the only way that my

0:00:48.360 --> 0:00:50.640
<v Speaker 1>wife can work from home. Uh, since she doesn't have

0:00:50.680 --> 0:00:53.760
<v Speaker 1>a laptop computer from her from her work. So I

0:00:53.800 --> 0:00:57.400
<v Speaker 1>talked to her into getting an Apple Airport Extreme, which

0:00:57.480 --> 0:01:00.400
<v Speaker 1>is actually Airport Express. The Airport Extreme him is the

0:01:00.560 --> 0:01:05.040
<v Speaker 1>regular hub. The Airport expresses a tiny, um tiny wireless

0:01:05.120 --> 0:01:07.560
<v Speaker 1>hub sort of looks like a giant white plastic now

0:01:07.600 --> 0:01:10.840
<v Speaker 1>and later, except it's got a little green light on

0:01:10.840 --> 0:01:12.920
<v Speaker 1>one side and some ports on the other side. And

0:01:12.920 --> 0:01:14.880
<v Speaker 1>what this does is I can plug this into my

0:01:15.640 --> 0:01:18.800
<v Speaker 1>electrical outlet and it will hook up to the wireless

0:01:18.800 --> 0:01:21.560
<v Speaker 1>network and extend that network. But for this wired, this

0:01:21.640 --> 0:01:25.560
<v Speaker 1>old wired machine that I've got, we can actually plug

0:01:25.600 --> 0:01:28.759
<v Speaker 1>it into there and it will allow the wired access

0:01:28.840 --> 0:01:31.120
<v Speaker 1>to the wireless network, which is pretty nice. But it

0:01:31.200 --> 0:01:33.720
<v Speaker 1>also has a USB port on it which allows us

0:01:33.760 --> 0:01:37.199
<v Speaker 1>to hook up a printer. And now instead of having

0:01:37.360 --> 0:01:42.360
<v Speaker 1>to go down the hall and plug our laptop computers

0:01:42.360 --> 0:01:45.960
<v Speaker 1>into the printer itself and go ahead and you know,

0:01:46.120 --> 0:01:48.480
<v Speaker 1>get everything spoiled up and print it out, we can

0:01:48.480 --> 0:01:50.920
<v Speaker 1>actually turn on the printer, do work from the other

0:01:51.040 --> 0:01:54.160
<v Speaker 1>room and print something out over the wireless network. And

0:01:54.200 --> 0:01:57.680
<v Speaker 1>it's so much easier. It's so very convenient that uh uh.

0:01:57.760 --> 0:01:59.280
<v Speaker 1>You know, we're just really happy with the way it

0:01:59.360 --> 0:02:02.080
<v Speaker 1>worked out. And there are many different ways that you

0:02:02.120 --> 0:02:06.680
<v Speaker 1>can do wireless printing, um uh. And they date back

0:02:06.760 --> 0:02:10.640
<v Speaker 1>to well the mid to late nineties. That was really

0:02:10.639 --> 0:02:14.560
<v Speaker 1>when we started seeing infrared systems being used. I r

0:02:14.639 --> 0:02:18.359
<v Speaker 1>d A, which stands for the Infrared Data Association, came

0:02:18.440 --> 0:02:22.639
<v Speaker 1>up with this. It's a standard where computer signals are

0:02:22.720 --> 0:02:27.000
<v Speaker 1>converted into pulses of infra red light, and this light

0:02:27.120 --> 0:02:30.960
<v Speaker 1>is then sent to a receiver which then decodes the

0:02:31.040 --> 0:02:33.960
<v Speaker 1>signals and UH turns it back into a print shop

0:02:33.960 --> 0:02:36.560
<v Speaker 1>and your printer prints it out. And it requires some adapters,

0:02:36.600 --> 0:02:39.400
<v Speaker 1>both on the computer side and the printer side, but

0:02:39.440 --> 0:02:42.799
<v Speaker 1>it would allow you to print wirelessly, um, which is

0:02:42.840 --> 0:02:44.519
<v Speaker 1>kind of neat. You know, you got to cut back

0:02:44.560 --> 0:02:46.720
<v Speaker 1>on the cables that were cluttering up. I mean, I

0:02:46.720 --> 0:02:49.320
<v Speaker 1>don't know what your home office is like, but mine,

0:02:49.360 --> 0:02:51.760
<v Speaker 1>I've I've got it looks like a squid has exploded

0:02:51.800 --> 0:02:55.280
<v Speaker 1>behind my desk. So coming back on the cables is

0:02:55.400 --> 0:02:59.720
<v Speaker 1>very attractive. But it had some downsides to it too. Um.

0:02:59.840 --> 0:03:03.239
<v Speaker 1>The biggest downsite to infrared. The infrared approach is that

0:03:03.560 --> 0:03:06.440
<v Speaker 1>it requires line of sight. That means that there needs

0:03:06.480 --> 0:03:10.120
<v Speaker 1>to be a direct path pretty much between the transmitter

0:03:10.160 --> 0:03:13.280
<v Speaker 1>and the receiver. If there's not, then the signal just

0:03:13.440 --> 0:03:16.080
<v Speaker 1>doesn't make it and you won't get anything. So if

0:03:16.120 --> 0:03:18.519
<v Speaker 1>you put that printer in a room down the hall

0:03:18.600 --> 0:03:20.600
<v Speaker 1>and you send a print job, chances are it's not

0:03:20.639 --> 0:03:24.480
<v Speaker 1>gonna make it. Yeah, I've had pretty good experience using infrared.

0:03:24.600 --> 0:03:27.160
<v Speaker 1>When I try to change the channel with the remote

0:03:27.520 --> 0:03:31.080
<v Speaker 1>for my TV. However, trying to sink a Palm Pilot

0:03:31.200 --> 0:03:35.600
<v Speaker 1>and my old rev Aimac with the I r D

0:03:35.720 --> 0:03:38.200
<v Speaker 1>A port on the front, you know, mostly involved me

0:03:38.240 --> 0:03:41.920
<v Speaker 1>shaking it and going well won't you sink? So, you know,

0:03:42.400 --> 0:03:45.120
<v Speaker 1>it's sort of a it seems sort of limited in

0:03:45.120 --> 0:03:47.400
<v Speaker 1>that capacity. I'm guessing your wife would not want to

0:03:47.440 --> 0:03:49.720
<v Speaker 1>pick up that desktop computer and yell out why won't

0:03:49.760 --> 0:03:54.360
<v Speaker 1>you print? Well, I would talk about that. Okay, well

0:03:54.400 --> 0:03:58.160
<v Speaker 1>we'll move on. So so that's the the infrared approach,

0:03:58.200 --> 0:04:01.120
<v Speaker 1>but there are others as well. Um, one huge improvement

0:04:01.280 --> 0:04:06.920
<v Speaker 1>was taking the bluetooth approach. Um. Now, bluetooth technology doesn't

0:04:07.040 --> 0:04:10.320
<v Speaker 1>require line of sight, it's a it creates a personal

0:04:10.360 --> 0:04:14.280
<v Speaker 1>area network and um it uses radio signals instead of

0:04:14.320 --> 0:04:18.200
<v Speaker 1>infrared light. That's that's true. And computers are on a

0:04:18.560 --> 0:04:22.720
<v Speaker 1>on a higher scale than that than your mobile phone

0:04:22.720 --> 0:04:25.400
<v Speaker 1>would be. It's a pretty common mobile phone technology. There's

0:04:25.400 --> 0:04:27.919
<v Speaker 1>people with wireless earpieces you see that seem to be

0:04:27.960 --> 0:04:30.560
<v Speaker 1>talking to themselves in public places. You look kind of

0:04:30.560 --> 0:04:35.080
<v Speaker 1>like cyborgs, right right, Um they are. They're using Bluetooth

0:04:35.120 --> 0:04:39.760
<v Speaker 1>technology to communicate from the wireless earpiece to their phone, right,

0:04:39.920 --> 0:04:42.160
<v Speaker 1>and that you can find this in all sorts of things,

0:04:42.160 --> 0:04:45.200
<v Speaker 1>not just computers and printers and phones, but also a

0:04:45.720 --> 0:04:48.880
<v Speaker 1>MP three players and other devices as well. And um,

0:04:48.920 --> 0:04:52.560
<v Speaker 1>you can network multiple devices into the same Bluetooth network.

0:04:52.880 --> 0:04:55.719
<v Speaker 1>I think up to eight according to our Bluetooth article

0:04:55.720 --> 0:04:59.000
<v Speaker 1>and how stuff works, and um, so it's very handy

0:04:59.080 --> 0:05:01.360
<v Speaker 1>and and these devices can talk to each other and

0:05:01.360 --> 0:05:03.760
<v Speaker 1>and keep each other informed of where you are, and

0:05:04.000 --> 0:05:05.599
<v Speaker 1>there's lots of neat tricks you can do with it.

0:05:05.640 --> 0:05:08.240
<v Speaker 1>But as far as printing goes, uh, it just means

0:05:08.279 --> 0:05:10.360
<v Speaker 1>that you can have a printer in one room and

0:05:10.520 --> 0:05:13.120
<v Speaker 1>computers in other rooms and and have all those computers

0:05:13.120 --> 0:05:15.360
<v Speaker 1>be able to print to that printer. Um. But the

0:05:15.520 --> 0:05:19.440
<v Speaker 1>limitation is that, again the distance is not that great.

0:05:19.480 --> 0:05:23.240
<v Speaker 1>So if you are in a multi story home or

0:05:23.960 --> 0:05:26.560
<v Speaker 1>a very large ranch house where you've got the computer

0:05:26.640 --> 0:05:28.000
<v Speaker 1>on one and then the printer on the other, it

0:05:28.120 --> 0:05:30.720
<v Speaker 1>may not may not pick up the signal. Uh, And

0:05:30.720 --> 0:05:34.560
<v Speaker 1>in that case you have to go with a third option. Well,

0:05:34.600 --> 0:05:36.520
<v Speaker 1>but before we get to that, I was just going

0:05:36.560 --> 0:05:39.120
<v Speaker 1>to point this out that when we went to the

0:05:39.279 --> 0:05:43.600
<v Speaker 1>Consumer Electronics show, UM I saw a product that actually

0:05:43.680 --> 0:05:46.560
<v Speaker 1>ended up as an article on our site called how

0:05:46.600 --> 0:05:50.320
<v Speaker 1>ink Free Mobile Printers Work that Jane McGrath wrote, but

0:05:50.400 --> 0:05:53.279
<v Speaker 1>it was about the Polaroid Pogo, which is a very

0:05:53.360 --> 0:05:56.520
<v Speaker 1>small ink free printer that you can essentially stick in

0:05:56.520 --> 0:05:59.520
<v Speaker 1>your pocket and while you are out and about you

0:05:59.560 --> 0:06:03.799
<v Speaker 1>can take pictures with a Bluetooth enabled camera and send

0:06:03.800 --> 0:06:07.000
<v Speaker 1>the signals directly to this little bitty pocket Polaroid printer.

0:06:07.360 --> 0:06:10.200
<v Speaker 1>That was a pretty nifty bit of alliteration and print

0:06:10.240 --> 0:06:13.920
<v Speaker 1>things out wirelessly, so you can even the Bluetooth wireless

0:06:13.920 --> 0:06:15.560
<v Speaker 1>printing even allows you to do that. You don't have

0:06:15.600 --> 0:06:18.440
<v Speaker 1>to carry around a cable and have it, uh, you know,

0:06:18.520 --> 0:06:21.120
<v Speaker 1>something else to lose with you while you're out running around,

0:06:21.360 --> 0:06:24.200
<v Speaker 1>you know, taking nature photos or you know, going to

0:06:24.279 --> 0:06:26.400
<v Speaker 1>c e s and taking pictures that you want to print,

0:06:26.680 --> 0:06:29.080
<v Speaker 1>you know, whatever you happen to be doing while you're

0:06:29.160 --> 0:06:30.440
<v Speaker 1>you're on the gust. So it's that that's sort of

0:06:30.440 --> 0:06:33.520
<v Speaker 1>a neat application of it that that you wouldn't be

0:06:33.560 --> 0:06:35.839
<v Speaker 1>able to do if you had to worry about, you know,

0:06:36.600 --> 0:06:38.200
<v Speaker 1>keeping track of all your cables, or at least it

0:06:38.200 --> 0:06:39.920
<v Speaker 1>would make it a little bit more difficult. That's true.

0:06:39.960 --> 0:06:45.680
<v Speaker 1>That's true. Bluetooth has made mobile printing uh possible. Before

0:06:45.800 --> 0:06:47.840
<v Speaker 1>it was just uh, you know, you're pretty much were

0:06:47.839 --> 0:06:50.039
<v Speaker 1>tied down to some sort of physical location. But that's

0:06:50.080 --> 0:06:52.680
<v Speaker 1>that's pretty nifty nifty now granite Bluetooth also has some

0:06:53.120 --> 0:06:57.880
<v Speaker 1>other downsides besides the range. Um. We didn't actually mention that,

0:06:57.920 --> 0:07:02.200
<v Speaker 1>but there's some security issue, is there too Bluetooth devices.

0:07:02.279 --> 0:07:05.719
<v Speaker 1>It's it's if you're not careful, you can easily get

0:07:06.360 --> 0:07:10.080
<v Speaker 1>eaves dropped upon or blue jacked. We talked about that

0:07:10.160 --> 0:07:13.560
<v Speaker 1>in another podcast. Um, so yeah, there's some downsides to

0:07:13.640 --> 0:07:17.600
<v Speaker 1>that technology as well. That's that's true. And um, you

0:07:17.600 --> 0:07:19.360
<v Speaker 1>know that seems to be common with all the different

0:07:19.400 --> 0:07:22.239
<v Speaker 1>wireless platforms, uh you know. And then and of course

0:07:22.280 --> 0:07:25.280
<v Speaker 1>the the largest and more common of these, especially with

0:07:25.440 --> 0:07:30.480
<v Speaker 1>regard to wireless printing, is WiFi, which is the uh

0:07:30.480 --> 0:07:34.760
<v Speaker 1>A O two dot eleven standard A b g N

0:07:35.240 --> 0:07:39.840
<v Speaker 1>element O P see um. And basically what that is

0:07:39.840 --> 0:07:42.320
<v Speaker 1>is this is the wireless network that you access when

0:07:42.320 --> 0:07:44.520
<v Speaker 1>you go to your local coffee shop and you open

0:07:44.560 --> 0:07:47.160
<v Speaker 1>your laptop and there you go, there's a network. Well,

0:07:47.600 --> 0:07:49.880
<v Speaker 1>you know, this is the same kind of printing that

0:07:49.920 --> 0:07:52.160
<v Speaker 1>you might find it, you know, maybe a bigger office,

0:07:52.200 --> 0:07:54.960
<v Speaker 1>not a small office, home office. More like, uh, you

0:07:55.000 --> 0:07:58.160
<v Speaker 1>know a the wireless printer on your floor if you

0:07:58.200 --> 0:08:02.000
<v Speaker 1>have one at your company. Um, and it's what I've

0:08:02.000 --> 0:08:04.080
<v Speaker 1>got set up in my my office at home, I've

0:08:04.080 --> 0:08:07.560
<v Speaker 1>got a WiFi extender and that's how it's making a connection. Yeah,

0:08:07.560 --> 0:08:09.800
<v Speaker 1>I have the same sort of thing. It's UM, use

0:08:09.840 --> 0:08:13.840
<v Speaker 1>a wireless router to create my wireless network. And uh.

0:08:13.960 --> 0:08:17.800
<v Speaker 1>This ATO two point eleven standard was set by the

0:08:17.880 --> 0:08:22.240
<v Speaker 1>Institute of Electrical and Electronics Engineers the I Triple E,

0:08:22.600 --> 0:08:24.800
<v Speaker 1>or as Chris has learned, the way I like to

0:08:24.800 --> 0:08:31.040
<v Speaker 1>say it is as my friends in Louisiana do I E. Uh,

0:08:31.120 --> 0:08:34.320
<v Speaker 1>Joe just never gets old, does it. Uh? Not to you, No,

0:08:34.440 --> 0:08:36.480
<v Speaker 1>not to me, And that's all that really matters. But

0:08:36.520 --> 0:08:39.360
<v Speaker 1>at any rate, so this standard allows you to to

0:08:39.559 --> 0:08:43.920
<v Speaker 1>transmit signals and it's a it's a radio signal like Bluetooth,

0:08:43.920 --> 0:08:47.560
<v Speaker 1>except it's more powerful, so there's a greater range. UM. Now, grant,

0:08:47.640 --> 0:08:49.240
<v Speaker 1>if you have a really large house, you might need

0:08:49.280 --> 0:08:53.400
<v Speaker 1>an extender so that they they the signal can go

0:08:53.440 --> 0:08:56.600
<v Speaker 1>throughout the entire home. Uh. Some people just recommend that

0:08:56.640 --> 0:09:01.720
<v Speaker 1>you put your router um in the middle, or if

0:09:01.760 --> 0:09:03.880
<v Speaker 1>you have a multi story home in the top level

0:09:04.000 --> 0:09:06.480
<v Speaker 1>of your home to kind of extend the signal throughout

0:09:06.480 --> 0:09:08.880
<v Speaker 1>the rest of the building. Um, that can work, or

0:09:09.000 --> 0:09:11.839
<v Speaker 1>you might just need to buy a booster of some sort.

0:09:12.040 --> 0:09:16.280
<v Speaker 1>But that that is, uh, there's one way to print wirelessly. Now.

0:09:16.280 --> 0:09:18.560
<v Speaker 1>In fact, you were saying that there's some printers coming

0:09:18.559 --> 0:09:21.240
<v Speaker 1>out that or there are printers that are out that

0:09:21.360 --> 0:09:24.480
<v Speaker 1>have these wireless cards already installed, so you don't even

0:09:24.480 --> 0:09:27.440
<v Speaker 1>have to buy an adapter. Yeah, the black and black

0:09:27.480 --> 0:09:32.439
<v Speaker 1>and white UM back to school Uh circulars I've seen lately. Uh,

0:09:32.800 --> 0:09:37.800
<v Speaker 1>ironically enough in color UM have a lot of printers.

0:09:37.800 --> 0:09:39.640
<v Speaker 1>I was surprised a lot of them have the print

0:09:39.640 --> 0:09:41.480
<v Speaker 1>servers built in. And they're using that as a major

0:09:41.480 --> 0:09:44.680
<v Speaker 1>selling point right now. Uh they're saying, you know, get

0:09:44.679 --> 0:09:47.520
<v Speaker 1>a printer back to school and you know what's wireless.

0:09:47.520 --> 0:09:50.240
<v Speaker 1>It's wireless. And I'm thinking, well, that's that's kind of new,

0:09:50.280 --> 0:09:54.440
<v Speaker 1>because you know before that just wasn't a selling point.

0:09:54.440 --> 0:09:56.959
<v Speaker 1>But I guess with uh, you know, with the state

0:09:57.040 --> 0:10:00.000
<v Speaker 1>of networking in the home right now, it's pretty common

0:10:00.000 --> 0:10:01.720
<v Speaker 1>and to have our wireless network, it would be very

0:10:01.760 --> 0:10:04.360
<v Speaker 1>easy to uh to do that, and if you didn't

0:10:04.360 --> 0:10:07.480
<v Speaker 1>have if you bought a laptop or desktop computer and

0:10:07.559 --> 0:10:09.880
<v Speaker 1>didn't have a wireless network, but you know, had the

0:10:09.920 --> 0:10:11.960
<v Speaker 1>equipment install, had the card install, that would be very

0:10:11.960 --> 0:10:15.400
<v Speaker 1>easy for you to network right to that printer across

0:10:15.440 --> 0:10:17.080
<v Speaker 1>the room. Then you don't have to worry about fishing

0:10:17.080 --> 0:10:19.600
<v Speaker 1>the cables over or trying to to hook it up

0:10:19.640 --> 0:10:22.280
<v Speaker 1>to the computer if you don't have room. It's just

0:10:22.480 --> 0:10:25.319
<v Speaker 1>a nice advantage of you know, having that baked right

0:10:25.360 --> 0:10:29.040
<v Speaker 1>into the printer hardware. And and since wireless networks are

0:10:29.080 --> 0:10:32.079
<v Speaker 1>getting more popular, I guess it's it would be irresponsible

0:10:32.080 --> 0:10:37.160
<v Speaker 1>of us not to address the security issues of of WiFi. Um,

0:10:37.280 --> 0:10:39.840
<v Speaker 1>if you have a wireless network, it is really important

0:10:39.880 --> 0:10:44.760
<v Speaker 1>that you make sure it's secure. That's because anyone going

0:10:44.840 --> 0:10:47.520
<v Speaker 1>near your house, anyone who or apartment or whatever, if

0:10:47.559 --> 0:10:49.560
<v Speaker 1>if they can, if they can detect that network and

0:10:49.600 --> 0:10:53.839
<v Speaker 1>it's unsecure, they could tap in and at at the

0:10:53.960 --> 0:10:55.800
<v Speaker 1>very least they could end up using up all your

0:10:55.800 --> 0:10:58.400
<v Speaker 1>bandwidth and you would get a huge bill from your

0:10:58.600 --> 0:11:01.880
<v Speaker 1>internet service provider. But at worst they would be able

0:11:01.880 --> 0:11:05.520
<v Speaker 1>to infiltrate your network and check up on all your

0:11:05.520 --> 0:11:08.040
<v Speaker 1>personal information. If you do internet shopping, they might even

0:11:08.040 --> 0:11:09.720
<v Speaker 1>be able to hack into that sort of thing or

0:11:10.080 --> 0:11:16.240
<v Speaker 1>bank records. It's really really dangerous to have an unsecured network. So, uh,

0:11:16.440 --> 0:11:19.040
<v Speaker 1>make sure that you you do all the right steps.

0:11:19.160 --> 0:11:21.320
<v Speaker 1>Make sure you you have a firewall in place, and

0:11:21.360 --> 0:11:24.440
<v Speaker 1>that you've got the settings set properly. Make sure that

0:11:24.480 --> 0:11:28.200
<v Speaker 1>you have a difficult password so that people can't just

0:11:28.280 --> 0:11:31.080
<v Speaker 1>guess at what it is. It's um, it's no joke.

0:11:31.280 --> 0:11:34.040
<v Speaker 1>I mean it. It can really really ruin lives if

0:11:34.080 --> 0:11:37.520
<v Speaker 1>you don't if you don't secure that wireless network. Yeah,

0:11:37.559 --> 0:11:40.400
<v Speaker 1>you know, I've actually read reports that well. Of course,

0:11:40.440 --> 0:11:44.520
<v Speaker 1>because the internet connection is traceable to you, people have

0:11:44.880 --> 0:11:49.560
<v Speaker 1>been in trouble with the Recording Industry Association of America

0:11:49.640 --> 0:11:54.920
<v Speaker 1>because yeah, r I double a yeah, And basically people

0:11:55.200 --> 0:11:58.920
<v Speaker 1>were camping out outside people's homes using their wireless connection

0:11:58.960 --> 0:12:02.640
<v Speaker 1>and downloading music from some of the file sharing services.

0:12:02.640 --> 0:12:05.120
<v Speaker 1>And the people who are getting hit with these lawsuits

0:12:05.120 --> 0:12:07.200
<v Speaker 1>and there haven't been I haven't seen but maybe one

0:12:07.280 --> 0:12:09.200
<v Speaker 1>or two, I think, and it's been some time now,

0:12:09.600 --> 0:12:12.320
<v Speaker 1>but you know, I you can imagine what it would

0:12:12.320 --> 0:12:15.160
<v Speaker 1>be like if somebody came up and said, here's a uh,

0:12:15.240 --> 0:12:18.400
<v Speaker 1>you know, a summons. You're being sued for downloading music

0:12:18.440 --> 0:12:21.160
<v Speaker 1>and you're thinking, well, I've never done that, you know,

0:12:21.240 --> 0:12:23.760
<v Speaker 1>But if you leave your wireless network open, I mean,

0:12:23.800 --> 0:12:25.760
<v Speaker 1>they may not necessarily be going through your files, but

0:12:25.800 --> 0:12:27.959
<v Speaker 1>they may be using your internet connection to do something

0:12:27.960 --> 0:12:30.520
<v Speaker 1>that you might not want to use for. But um,

0:12:30.559 --> 0:12:32.520
<v Speaker 1>as far as the printers go, I saw an article

0:12:32.600 --> 0:12:37.400
<v Speaker 1>in on the INC website for INC Magazine Business Magazine,

0:12:37.480 --> 0:12:40.320
<v Speaker 1>and they say that really, if you could just add

0:12:40.360 --> 0:12:43.360
<v Speaker 1>it to the VPN, added to your your firewall, put

0:12:43.360 --> 0:12:46.120
<v Speaker 1>it behind the firewall, you can still enjoy the benefits

0:12:46.120 --> 0:12:49.959
<v Speaker 1>of using wireless printer without necessarily having to worry about

0:12:50.160 --> 0:12:52.400
<v Speaker 1>going into the printer and you know, messing with the

0:12:52.400 --> 0:12:55.160
<v Speaker 1>sittings because some of those are easier to to affect

0:12:55.200 --> 0:12:58.360
<v Speaker 1>than others. So um, you know it may be just

0:12:58.440 --> 0:13:02.080
<v Speaker 1>that simple to to keep your printer secure. Right. Well,

0:13:02.120 --> 0:13:04.800
<v Speaker 1>I guess that wraps up this discussion on wireless printing

0:13:04.840 --> 0:13:08.040
