I am trying to set up a printer using smb:// via CUPS. I am failing miserably. Here's the appropriate snippet from the cups logs: D [22/Sep/2014:08:27:00 -0700] [Job 37] Started backend /usr/lib/cups/backend/smb (PID 27168) D [22/Sep/2014:08:27:00 -0700] [Job 37] Connected with username/password... D [22/Sep/2014:08:27:00 -0700] [Job 37] Unable to auto-configure PostScript Printer - no bidirectional I/O available! D [22/Sep/2014:08:27:00 -0700] [Job 37] PID 27167 (/usr/lib/cups/filter/commandtops) stopped with status 1. D [22/Sep/2014:08:27:00 -0700] [Job 37] Hint: Try setting the LogLevel to "debug" to find out more. D [22/Sep/2014:08:27:00 -0700] [Job 37] PID 27168 (/usr/lib/cups/backend/smb) exited with no errors. It connects, authenticates, starts smbspool, but then fails with the bidirectional error. I don't know what is throwing this error, so I am hoping someone on this list can help me out with some lead. Thanks! --
