Bug#1033625: closed by Brian Potkin <claremont102@gmail.com> (Re: Bug#1033625:)



Hi Brian,

thanks for your help. But isn't it still a bug that cups is creating a printer(-queue) that not only does not work, but also when using it opens connections to the printer for hours? I think about the situation, that you have many bookworm clients in the network, this could amount to a denial of service.

I deleted the not working Kyocera_ECOSYS_M5526cdw but cups keeps recreating it when I connect to the corresponding network.

Package: cups
Version: 2.4.2-2
Severity: important
X-Debbugs-Cc: johan.kroeckel@gmail.com

I am using a Kyocera Ecosys m5526cdw over the network. Printing stopped working (worked with this version before).

Now when I try to start a print job cups ends with a message "Der Druckauftrag wurde nicht angenommen.". BUT:

Now cups connects to the printer (LED on printer lights up as long as the pc is on) but nothing is printed. When I reboot, the LED stops to blink as long as the system is not completely booted, then the connection starts again.

After running cupsctl --debug-logging, error_log grows by around 30 megabytes per hour.
