Hi konrad, Here is my recipe to downgrade. Don't do that unless you know what you do.
- go to https://packages.ubuntu.com/groovy/libcups2, scroll down to « Download libcups2 », click on the link corresponding to your architecture, then choose a mirror server, and download the libcups2_2.3.3-3ubuntu1_amd64.deb file. - do the same with https://packages.ubuntu.com/groovy/cups to get cups_2.3.3-3ubuntu1_amd64.deb - open a terminal to get a shell, and go to directory where you stored the two .deb file - type " sudo dpkg -i cups_2.3.3-3ubuntu1_amd64.deb libcups2_2.3.3-3ubuntu1_amd64.deb " to install these packages. - then restart cups with " sudo systemctl restart cups.service " Be aware that further package upgrade ( sudo apt upgrade ) will not work until you issue " sudo apt --fix-broken install " to get back the current cups and libcups2 packages. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to cups in Ubuntu. https://bugs.launchpad.net/bugs/1936864 Title: Samsung printer can't print after 21.04 update Status in cups package in Ubuntu: Confirmed Bug description: Hi, Since 21.04 update, I can't print any document with my Samsung ML-1665 laser printer. When I send a 1 page PDF, the printer warms up, the job appears to be successful, but no document is printed. A few minutes later, the printer prints this message : "INTERNAL ERROR - Incomplete Session by time out POSITION : 0x46069 (286825) SYSTEM : h6fw_5.37/os_hook LINE : 1226 VERSION : SPL 5.37 09-04-2009 " If I send the PDF to the printer twice in a row, the printer prints this message : "INTERNAL ERROR - Incomplete Corrupted Data POSITION : 0x38f72 (233330) SYSTEM : h6fw_5.37/xl_image LINE : 154 VERSION : SPL 5.37 09-04-2009 " The problem happens with either Splix or Postscript-Samsung driver. ==== Workaround === downgrade cups and libcups2 to version 2.3.3-3ubuntu1 (from Ubuntu 20.10 Groovy) After these 2 package downgrade, all work as expected.
