Canon Printer Won't Connect/Print

llewellen · 12-08-2020, 11:14 AM

Manjaro with Awesome WM (both up to date)
Canon Pixma TR4527 connected via USB and turned on
CUPS recognizes the printer as Local Printer

When I send a job to the printer nothing happens - no printing, no error message, no job in the queue.

Code:

~ >>> pacman -Q cups                                                                                                            
cups 2.3.3-3
~ >>> pacman -Q cnijfilter2                                                                                                           
cnijfilter2 6.00-1
~ >>> systemctl is-enabled org.cups.cupsd.service                                                                                     
enabled
~ >>> systemctl is-enabled org.cups.cupsd.socket                                                                                      
enabled
~ >>>

What have I overlooked?

Put CUPS into debug mode (more verbose logging) with

Code:

sudo cupsctl --debug-logging

Send a print job and then examine the CUPS error_log for errors (particularly filter-related output). It's can be a lengthy log, so use egrep to filter for output containing "filter" and error"...

Code:

egrep -iA3 "filter|error" /var/log/cups/error_log

Copy the log to https://pastebin.com/ and post the link to it here so that others can advise further.

I don't know. Does this help?

OK, will do. I have to go out for some appointments but will get to it later today. I should have mentioned that this is on a different laptop, the one I keep alive for experimenting and a backup. The other one you helped me with is working fine.

I saw those but couldn't diagnose my problem from what is there: I get nothing at all. No print. No error message. Nothing.

The CUPS GUI shows a definite working dialogue with the printer. It has correctly identified my printer. When the printer was turned off, CUPS correctly showed it as off/disconneted. When I turned the printer on, CUPS showed it as idle.

I listed in my OP what I have installed on that computer. Is there something missing that is necessary?

Examination of the error_log will be helpful here.

I decided not to mess with this. I am unimpressed with the Awesome WM so I'm going to try something different and will dial in the printing function at that time. Thanks for looking at this.

All good. Whatever works for you.
