I have a Canon Maxify 2750.

Up until now I've been using the standar linux drivers for it but they have a serious limitation I really need to solve which is I can only print one page at a time, on one sheet of paper. Printer is capable of full duplex printing.

If been able to install the drivers before but now I'me being confronted with an unexpected _"("_ error. Nothing more, nothing less.

I run the install script and it just fails.

Can someone lend a hand on this, please?

Richard Stallman wept.

I get the reference and I second that one.

Gutenprint

https://openprinting.org/driver/gutenprint/

Which distro are you using? GNU/Linux Debian?
Debian based distro?

Debian stable

https://packages.debian.org/trixie/printer-driver-gutenprint

The proprietary drivers for my printer are 1GB large.
Printing turns a document into a postscript file and sends that to the printer, what the fuck does it need 1GB of data for that??

Name and shame the printer company. That's infuriating to read.

Those are the Windows drivers for a Kyocera printer-scanner-combo.
Under Linux it runs out of the box with the drivers included in CUPS.

"Fuck Yooouuu Kyocera, and Fuck Yoooouuuu Windoze!!!" -Emporer Akihito, South Park "Whale Wars" reference

What's the exact error it's giving?

install.sh: 27: Syntax error: "(" unexpected

Just like that.

I've installed the gutenprint driver but my specific printer is not listed as a supported model. Testing it as I write this but with no particular hopes...

edit: and no, it still prints one sheet at a time, no duplex, and it botching the image printing quality

I found it listed under gimp-print.sourceforge.io/p_Supported_Printers.php listed as Experimental. Gutenprint is originally Gimp-Print.

It's labelled as "Canon MAXIFY MB2750" on that page. In the terminal, what's the output of:

gutenprint-printer-app devices

?

I haven't installed the GUI

The printer remains as is, faulty

From screenshots of having the GUI installed (It's looking like some sort of Web Config or Printer Settings pave that has toggles for 2-Sided/Duplex printer, as well as playing with the quality of the print jobs. Maybe I was misunderstanding thr purpose of the gutenprint-printer-app

Give it a go, we're curious, and I'm invested in you overcoming this silly printer hoops-and-loops getting just the basic features ironed out.

Do it. Do it now.

Sorry to inform you that besides filling my hard drive with unnecessary clutter, my printer remains as was.

Now... How do I purge my system from all this?

bash simply returns a command not found message when invoking gutenprint-printer-app

sudo snap remove gutenprint-printer-app

Then

sudo apt purge snapd

Sorry I couldn't be the fixer here. No disrespect meant, just trying to help. LOLseas

No worries. Somewhere, somehow, the solution awaits.
