after I reinstalled cups service, my printer not works any more ; I get this message: "couldn't start the printer please check your printer configuration"
in the journalctl they are some rows that I think are connected with this problem: ---------- Apr 21 10:25:04 pluto cupsd[1023]: REQUEST localhost - - "POST /jobs/ HTTP/1.1" 200 182 Cancel-Job successful-ok

as well I tried to understand the problem I was not able to do it.. :
I looked the configuration files : /etc/cups/cupsd.conf /etc/cups/printers.conf I reinstalled HPLIP without succes..
I found also some information that need create or configure a coups-filter, but I am not able to do this...
I would like some help in this problem
thank you
