I'm having some trouble with printing on my system. The KDE printer manager shows "client-error-bad-request" and no other information. When I run the KCM from the command line, I also get "kcmshell(17286) KCupsRequest::serverError: status unrecognised: 1024" on the console. I wasn't able to find any useful information on this issue on google or these forums; not even what the 1024 status code means. It seems to me that this may be a bug in the kcm_printer_manager module, but I'd like to rule out other possibilities first. Unfortunately, I don't know what to try from here. I'll provide as much potentially relevant information as I can think of below.
Changes since last successful print job:
Multiple updates to KDE packages
Update to cups that changed systemd unit file names.
Stopped and disbled old units
daemon-reload
Enable and start new units
Other updates to cups since then, if I recall correctly.
Packages and versions:
kdeutils-print-manager 4.14.3-1 (owns kcm_printer_manager module for kcmshell4)
kdebase-runtime 4.14.3-1 (owns kcmshell4 binary)
cups 2.0.1-1
libcups 2.0.1-1
systemd 218-1
linux 3.17.6-1
Let me know if any other information might be helpful.
