Samsung printer can't print after 21.04 update

[Laurent Riffard]

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.

how to do this downgrade? I am affected by this issue too and basically my business is stopped now :(

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.
