The following question is redarding a Canon Lasershot printer using the ccp "compiler" via Linux ABI which has stopped working with CUPS, suddenly. The following messages are stored in the error file /var/log/cups/error_log: X [12/Feb/2017:12:17:14 +0100] kevent() returned Bad file descriptor What is this message about? E [12/Feb/2017:12:18:43 +0100] Returning IPP client-error-not-possible for Cancel-Job (ipp://localhost:631/printers/Lasershot) from localhost When a file is printed, CUPS accepts it, then it disappears and the printer is always "idle". Of course the printer is both ready and accepting jobs. From "localhost:631" the test page can be selected, it won't print anything, but also not show any error in the printer overview or detail page. The command "lpstat -a" lists the printer correctly. E [12/Feb/2017:12:18:45 +0100] Unsupported character set "iso-8859-15" Nothing on the whole system defines iso-8859-15, it is a UTF-8 system, configured that way in all relevant configuration files. E [12/Feb/2017:12:18:45 +0100] Returning IPP client-error-bad-request for CUPS-Get-Printers (no URI) from localhost No idea what this means. As I said, there are no error messages in the web page or in the log file that indicate an error with converters, filters, or backends. W [12/Feb/2017:12:18:57 +0100] [Job 2216] The printer is unreachable at this time. The last message is printed every 30 seconds. There has not been an update for some time now, and the last time I checked, the printer worked, both from LibreOffice (it is also configured in "spadmin.bin") and from "localhost:631" / test page. What could cause CUPS's hick-ups? I didn't change anything... ;-) -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
