No Printing on MF5750 with Ubuntu 16.04.3 LTS #12

Closed waldo99 closed 6 years ago

waldo99 commented 6 years ago

Thanks for a great driver. This has worked for me in the past for my MF5750.

Now I'm on LXLE (based on Ubuntu 16.04.3 LTS). Compiled properly (with a couple warnings I ignored) and installed. I created udev rules and mapped the printer correctly to /dev/canonMF5750 and set it to print to file:///dev/canonMF5750. However, after sending the print command, nothing happens. Printer doesn't react. Printer queue shows that the job was processed (rendering completed). Printer works fine in Windows. Tried the usual troubleshooting. Maybe something in a new cups package broke it?

Any help?

Thanks in advance!

I have the same Issue on 16.04.03 LTS and on the current raspbian release. Hope this will be resolved as its a great printer

Does /dev/usb/lp0 exist before and after print attempt? Also try increasing LogLevel to debug in /etc/cups/cupsd.conf and check CUPS log files.

upon printing test page from cups web page I get these logs with cupsctl --debug-logging

Just installed Ubuntu 16.04.4 (x64) for test and it works the same way as elsewhere. The default CUPS libusb backend prints one job, then printer displays something like "DATA ERROR". File /dev/usb/lp0 (or a symlink created by udev) works fine.

Found a new workaround for the USB problem - blacklist the usblp module: 9240388521d3177c4192fcfcb0eaa3a531f6c719

Added carps.usb-quirks to make CUPS libusb backend work. No more file:// manual configuration, just add the printer and print: 8f01a98f28a61b38766b6a5bd39e0e298a527365

Latest build works great. Can print multiple pages successfully. Thanks! It's wonderful when a developer continues to support even years after he wrote it. :)

ondrej-zary commented 6 years ago

I've just tested MF5730 and "delay-close" was not enough to print more than one job (no error on LCD but nothing more could be printed). Changed the workaround to "no-reattach" and it works now.
