what the printing device today is.
And in this video, I will talk about basic architecture off professional printing device, as it is today. So I'm not going to talk about home printing. The waste is that you connect to your by fire. Are you? Use years be cable to connected your printer PC?
Then I'm going to talk about the fact that printing devices are usually the most neglected part of I T. Security,
and I am also going to talk. About two different types of printing devices exist today,
So when we talk about the architecture or printer,
we have imaging mechanism, and that mechanism can be based on name, jet or laser.
basically, these are only two in use today. Enough is printing that are widespread. There are some other technologies, but they plan not going to mention them. So this is the physical part of printer that puts ink on the paper.
Then you have a rendering boards, so it's called Mother Board. It's called the, uh, baseboard. It's called Rendering Board. It's called for material depending on the manufacture, but it's basically the part of printer that
produces the image that is going to be placed on paper.
Then we have a power board or engine border, whatever. It's cold, and it's part of a printer that is actually handling the physical part of the printer. So imaging mechanism.
And it's usually containing high power, high wattage parts there because, for example, if you have ah, laser printer, you have a Fuser infuser is operating or 110 or 212 waltz, 220 worlds, depending on on part of the world where you are in.
So this is this is a part of the printer that is usually separate from rendering board,
and it's their toe provide, ah,
high power consumption parts with power and also to transfer data to them.
So this is what the printer is consisting off. So these three parts and in all of our talking about printing security, I'm going to focus on just one thing on the rendering board.
So Rendering Board is a part of printer that is vulnerable to security
issues on, and it's also the one that has all the processing power in the so. What rendering board contains is, for example, input output connectors like network connectors wire de progresses or WiFi connection with the antenna
or USB, which is still used on printers today,
Then you have a process, sir,
and this processor is usually not just some
week processor. It can go with the frequencies upto 11.5 get hurt. So it's, Ah,
very computing capable device.
Then you have Firmer, which is located somewhere on the board in terms off non volatile memory.
Then you have memory on a printer, like on a PC. So you have slots. For example, On this board, you see that you have two slots for memory that are pretty much identical, like those you confined on notebooks.
And then you have some kind of non volatile storage, which can be HDD or SST or used the flesh and these things. They're not necessarily always in a printer, but in modern devices, the network devices, there is always some kind of non volatile storage.
is a part of a printer that is containing basically the operating system on the printer and which is the part that also,
uh, is there to provide the core
function of a printer, which is to print a print job. So when you print something, you get print job sent to the printer. It can be through. USB can be sent through the network, whether wired of Marlys
and then that print job have print file has to be converted in in tow, essentially dots that are going to be placed on the paper.
Then Firmer also handles authentication of users and the wise if that function is enabled or
possible on that device,
and it also allows execution off layering on layering of, perhaps so, if you have some add ons or APS or whatever they're called, it really depends on the manufacture on the printer. Firmer is there to allow the these APS, or or plugging is to be executed.
And also, if they're layered, it has toe
take care of these priorities, and also what former also does is it handles traps and alerts that exist
in a printer, which are set to there but somebody some kind of management software.
So these two things the rendering board and the firmer unity are the target off. What is, uh, it's a space on which cyber attacks on the printing the wiser, targeted
so at the end of this lesson, we just talk about
Let's do a small learning
trick. So the first question is what is not the part off rendering board? Actually, the only question and the possible answers our memory
and ah ah, raid hard this controller
trade hard, this controller. So
this is not the part off rendering board. There are no rendering boards that I'm aware off on on a printer that has raid hard drive controller. OK, so in this video, in this lesson, you have learned about to the architectural Metro printing devices today. So
basically how it's composing off course what it represents. Two days of what the printing device today is. Then you learned about the fact that printing devices are the most neglected part of I T. Security today,
and you also seen what kinds of four types of devices exist so printers in the fifties. And what are their differences in terms off architectural, construction or and security? Most importantly,
and the next, the Western or video, you will be able to learn about potential damage that can be done by
printing device that has been compromised
