Till,
system-config-printer version 1.3.8 works
version 1.5.6 does not work.

My impression is that the command file generated in printerproperties.py 
using
         with tempfile.NamedTemporaryFile(mode='wt') as tmpfile:
             tmpfile.write ("#CUPS-COMMAND\n%s\n" % command)

has a size of zero bytes when the job is submitted to cups
maybe due to buffering?

in the older working version 1.3.8 the command file is generated using
         (tmpfd, tmpfname) = tempfile.mkstemp ()
         os.write (tmpfd, "#CUPS-COMMAND\n%s\n" % command)
         os.close (tmpfd)

Title:
  commands passed to cups fail. File missing

Status in system-config-printer package in Ubuntu:
  Incomplete

Bug description:
  xubuntu 15.04  64 bit
  system-config-printer 1.5.6

  when I click the button "Print self test page", I expect the printer to produce a self test page
  instead I get error "client-error-bad-request" and no self test page.
  the cups error log has the entry
  Print-Job client-error-bad-request: No file in print request.

  Note that I can get the printer to generate the self test page by
  printing a command file from terminal.

  So it seems that system-config-printer is not providing the command
  file, or not providing the command filename to cups?
