"debug1" is not an option for LogLevel. Use cupsctl LogLevel=debug > and this finally gives an error_log: > > E [08/Jan/2018:14:31:48 +0100] [cups-driverd] Bad driver information > file \"/usr/share/cups/model/samsung/cms/CLP-310sc.cts\"! > E [08/Jan/2018:14:31:48 +0100] [cups-driverd] Bad driver information > file \"/usr/share/cups/model/samsung/cms/CLP-300cms\"! [Snip] This is not the required error_log. Please retry after setting the LogLevel to the correct value. Also, previously you got > lpinfo: Ungültiger Dateideskriptor (invalid file descriptor) This was because cupsd was not running. You must restart it after using cupsctl (bug #861470). Cheers, Brian.
