CUPS uses 25% CPU when PC starts and ML-2510 printer doesn't work

The new Cups 2.0.2 uses 25% of my CPU when the PC starts.

My Samsung ML-2510 printer doesn’t work anymore.

When I try to downgrade CUPS to 1.54, there is an Ruby error complaining about too many stacks.

Automatic configuration doesn’t recognize my USB-printer.

Have you tried adding and removing the printer? I currently don’t have access to it, but I printed to the very same printermodel yesterday. This was after the cups update.

saw similar problem end of February, read then solved by :-

“zypper install --force cups-filters-ghostscript” and “rccups restart”)

Re: [SOLVED] cupsd 100% CPU load

https://bugs.archlinux.org/task/42666

SOLUTION (this was a failure on Tumbleweed)!!!
to modify /etc/cups/client.conf
remove ServerName /run/cups/cups.sock and replace it with
ServerName localhost:631

==============================================================================

try one at a time and undo if trial has no effect

hth

PS: also read deleteing them re-installing ghostscript helps
