Hello, and greetings all.
This is my first post, as well as my first attempt at seeking assistance from a forum. Obviously, I'm new at this "Linux" thing, but I've got Faith that it is WAY GOODER than windows.

We're wanting/trying to re-connect everything we've got into a new network, including our printer/fax/copier (named above)

We intend to use a network switch (10 port) connected to our router.

If I recall correctly, when we used windows towers we had to install the drivers before connecting the usb cable.

I've been given a few different links, with the premise of "you could just...." and then everything went downhill from there. ALMOST everything on said links of 'just click here' or 'download and install that'.... didn't work.

It is very frustrating when you (I) don't know what's wrong, don't know where the problem is, so then I don't know what to ask/say/threaten with destruction to get the hardware to work.

Add that, to the fact that I've not been here long enough to earn my fancy decoder ring to activate the 'super-secret-squirrel-search' at the top of the screen. I know this because any attempt I've done to 'search' drivers, canon, our model, anything.... shows up as "no results".

I find that hard to believe. So, if we can one-day complete the secret-handshake ceremony, that'd be great!

This is the first quest of a multitude of items on the checklist, involving:
2 towers
2 tablets
1 laptop
1 mini-tower
1 printer
2 media players
1 dvr

Though the laptop and tablets are all wifi, everything else is/will be connected either with CAT5 or USB cable.

Who's up for the challenge, and I thank you for reading thus far. Hope you're having an excellent Good Friday. Linux Rules!

Welcome aboard Sean the Nailer. There will be some challenges along the way with learrnig new concepts. Don't be frightened though - as with most things familiarity with a new OS environment takes time. First, you'll need to download the Linux driver...
https://www.usa.canon.com/internet/p...eclass-mf4350d

The driver package (UFR II/UFRII LT Printer Driver for Linux V5.10) comes as a compressed archive file called "linux-UFRII-drv-v510-usen-09.tar.gz"

Once you have downloaded it (eg to your Downloads folder), it needs to be extracted. That can be done via your graphical file manager, usually by right-clicking on the file and then choosing Extract or similar. If you're felling brave it can be done via a terminal instead. You need to change directory to where it was downloaded eg
Once that's done, you can navigate to the directory (folder) it created and proceed with running the installer
*sudo is used to run the script as root (administrator privileges required).

Once complete you should find that you can now print to the Canon printer. Post again if anything was not clear, or you run into problems. We can ride along with you.

I have gotten this far, then everything comes to a 'screeching halt'.

This installer is recommended for the following distributions that are currently supported as of the release of this installer:
- Fedora/Ubuntu/CentOS 7.6/Debian 8.11/Debian 9.8 or later

and

If this installer is run under distributions for which the support period has ended, the installation of additional system libraries may be necessary after driver installation is complete.

Note that an internet connection is required for installation.

Do you want to continue with installation? (y/n)

and then, whenever I hit 'y' I get this:

Some system libraries could not be installed.
Refer to the Readme file for more information.
Do you want to continue with installation? (y/n)y

So, have I given enough information where you can say "Punch the 'X' key real hard, seven times, to show it who's boss,,, then it'll work?

(Please tell me it's something that simple)

And yes, I am VERY appreciative of your assistance so far.

I'm a bit surprised that the installer makes reference to RPM, as the dowwnloaded archive also includes DEB packages for the distros using that package management system. Hopefully, you downloaded the same package that I did from the link I provided.

In any case you could navigate to the Debian folder with your graphical file manager

Downloads > linux-UFRII-drv-v510-usen> 64-bit_Driver > Debian

...and right-click on the 'cnrdrvcups-ufr2-us_5.10-1_amd64.deb' and install with your packagemanager. That should take care of any dependencies.

This can also be done from a terminal using apt...

Full disclosure:

I know what I don't know. Which is the same things as saying "I don't know what I don't know".

But I do know this. I did the best I could, to follow what you had said. As default, so that I don't screw-up, I highlight then copy/paste directly into my 'black-screen' (forget the name at the moment) and all kinds of gobble-de-gook shows up, does things, I have to enter our secret-squirrel password thingy again, and then hit 'y', and then hit 'y' again, and then it shows:

~/Downloads/linux-UFRII-drv-v510-usen$ sudo apt install ~/Downloads/linux-UFRII-drv-v510-usen/64-bit_Driver/Debian/cnrdrvcups-ufr2-us_5.10-1_amd64.deb

Note, selecting 'cnrdrvcups-ufr2-us' instead of '/home/sean/Downloads/linux-UFRII-drv-v510-usen/64-bit_Driver/Debian/cnrdrvcups-ufr2-us_5.10-1_amd64.deb'
cnrdrvcups-ufr2-us is already the newest version (5.10-1).
0 upgraded, 0 newly installed, 0 to remove and 298 not upgraded.

(I was expecting fireworks)

So then I go back to what you'd said, and went via the 'synaptic Package Manager' thingy, and did a search for:
cnrdrvcups-ufr2-us
lo and behold, it actually IS there, and I'm able to actually select it, and then right click on it. But then I only get the option of:

Mark for removal
Mark for complete removal
properties

Those were the only options that were 'bold' or 'selectable' and I'm thinking "what the heck do I have to do to actually get the 'mark for installation' to be clickable.... and I tried doing that eleventy times, from eleventy different ways. All to no avail.

And then it hit me.

After ALL THIS TIME, and all these attempts, and all this frustration, it appears that I've actually now got the driver INSTALLED Into my tower! Woohoo...
We're now in the process of plugging CAT5 wires into our new Network Switch, so that I can actually attempt to print something out, to verify that I actually did accomplish this task.

Believe me, I realize that I could have just replied with 'done' or 'it worked' or 'completed', but for all the time, effort, attempts, and your assistance I figured you deserved to actually see what's been going on inside my brain/echo-chamber. In the hopes that you grasp the humor of it all.

Happy Easter

I'll post again here, when I've attained the elusive 'printing' and can work on the next quest in this evolution. Thank You.

Yes, the output you shared confirms it is installed. You may still need to configure CUPS (the printing system used by *nix and OS X) so that it can handle your printer though. Let us know if you need further help with that. When connecting the printer you your LAN, it is best to use a static IP address in general. The printer itself can use DHCP, but the router can be configured to reserve a particular address for the printer so that it effectively remains static.

Happy Easter to you as well. Looking forward to reading about your progress here. Remember to embrace the learning with all its challenges.
