welcome back to Prince Security Intermediate Course, and in this lesson, we're going toe. Continue the story about process of printing from the previous video.
00:10
So in this lesson, I will be talking about how it is the printer organized in companies with the emphasis to small, medium and large company.
00:21
So this red line represents the network, and when you're in a small company, you usually do it like this. You have bench off
00:32
PC's. That can be, for example, in one small office or in part off big office with cubicles. And then you have a network printer.
00:42
So what do you do? You install? I t installs a driver on these PC's
00:49
that are pointing to this printer its I P address or its Mac address
00:55
so on. And then you have another group off people who are part of World Group. They sit in a different part off off that huge office space, or they have their own separate office and they have a local printer attached to one of the PC's and they share it.
01:15
This is also a possibility,
01:17
and then again, you have a bunch of other people, and then you have one big network printer, which is maybe sitting on the floor by itself. It doesn't need a desk. It's a huge MSP that has a copying capabilities and prints a lot of pages per minute
01:34
so that device can be shared by everybody in the company. So then you would have to have on these machines here.
01:45
You would have to have a separate driver for that printer and these people who are primarily printing on this printer, they have driver that is pointing to that printer.
01:57
So what happens if that printer is not working? Then you have to give these people opportunity to print to some other device, and it's usually done by changing the address or i p address of the
02:12
printer in the driver. If these devices share the same driver or you just install all the drivers for the printers, you haven't a company to everybody. And then do you just set a default? 12 groups that are closest to the particular device.
02:30
So when you move
02:32
up a scale a little bit, so you have a medium company,
02:37
then you have a network
02:38
and then you have a Princess Petrovich you print
02:43
and then you have something called Manager Network Printers. So we have a group of people
02:49
and they are in active directory, set in a group. And then you have another group of people and they're using the other printer. And then you have ah, third group of people or fourth or fifth, and they are using other printers. And what then what you do?
03:06
Um, you There is a way to connect some kind of management device. Many rinse softer to the active directory of the company,
03:15
which says, Okay, this group here, the one on the top left. They can use these to printers by to because if one is out of the order, then you can use the other one,
03:28
and these printers are then assigned to this group. Then you have another group of people like these people sitting at the desktop PC's, and they're also using one of these printers, for example, this one and they have this one is a backup. But then you have 1/3 group of people, maybe in accounting or something,
03:46
and they're quite a lot of them. They are doing the invoice receiving. They're doing the shipping whatever,
03:53
and they need
03:55
to be able to print or at least two printers again. So you manage these things by usually finding some way to automatically assign a certain printer to certain people. Then you have something called Universal Print Driver, which is just
04:13
when you say print. It gives you the option to print on the ways one or device to you. Choose it. You print and that's it. Or you have two instances automatically
04:23
installed from that one driver on the machine.
04:29
Many manufacturers are doing that pretty much every big network printing. The manufacturer has the opportunity or option when you install their drivers, so this is typically a way to do it in a medium sized company. Now you move to a large company,
04:46
and then you had thought something's and the typical thing that we would add is authentication and device. So basically, on every
04:55
PC you have just one driver, which is a virtual driver with prince to a server
05:01
and then print job stays on the server. Then you have authentication server, so somebody wants to print what they have to get there, the print out of what they have been printing before
05:13
they come to a network printer, so nobody has a printing printer that configuration on table. It's all the hallway printers. So person goes there, they pick up, they come to the device, and then they do. The authentication of medication can be usually done by using your key card. Your
05:31
company pass, which who presented the door of the
05:35
card reader. And then you have the same card reader installed inside the device on next to the rice. You authenticate yourself into the ways
05:45
this device communicates with the authentication server, confirms it's you and then communicates with Princess or sees all the print jobs. You have
05:53
not being printed yet. You get them displayed on a display off the printer 50 you choose which one you want to print. They want to print them all. Or just some. They want to delete some because you may be printed one document wise,
06:05
and then you pick it up and
06:10
ah,
06:12
you you get your printouts. So why do we use the authentication? So, basically,
06:18
for example, imagine somebody personally has been printing document A. That is 10 pages. Then you printed document Ah, that is three pages long and then personally has again printed another document that's maybe 12 pages.
06:33
So the personnel reaches the printer before you, they see their first print out, the second print out. They pick your document, that is, in between them,
06:44
they take it to their deaths. They realize that there is, ah, some kind off,
06:49
uh, something that they haven't printed, and they just throw it away
06:55
or they bring it back to the printer. In the meantime, you have come to the printer. You have seen nothing in spring being printed. You go back to your desk, you print again, you pick it up and you never bother looking for it again. And this is the way than in big companies. People bring much more than they need.
07:13
Also, if you print ah document and then realize you made the mistake, you, for example, he didn't spell checking. You do a spell checking you print again.
07:21
It gets printed twice. So if it's a 50 page document and it's a big problem because it's a lot of paper and printing costs.
07:29
So this is why we have this authentication. There are other reasons, like if you're sending an email from MFP, divisive automatically populates your
07:39
email address and so on. But this is the main reason,
07:43
and this is the way that it is usually done in large companies.
07:47
So just the
07:49
short reminder. Why do we use a user authentication and device? Is it to know where the users are when they're not at the desk? Is it to avoid unnecessary printing? Or is it to increase lifespan of printing devices on? The correct answer is, of course, to avoid unnecessary printing.
08:09
So in this video you have learned the ways the printing is usually organized in companies
08:15
any next video. In this lesson, I'm going to talk about evolution of printing languages and what they are.
