When I run lpr <filename>.jpg the file prints out boderless (this is what I want).

When I run subprocess.call("/usr/bin/lpr " + tmp.name, shell=True) from a Python program, it prints out with borders.

I also tried to call it with "lpr -o StpBorderless=True -o StpiShrinkOutput=Expand .jpg" with the same borders still being printed.

Output from lpoptions shows the below (StpBorderless=True, and StpiShrinkOutput=Expand should make it borderless I think).

How can I execute lpr from a Python script to use the exact same options as if I executed it from command line?

  • are you sure that you are using the same lpr in both cases? What is the output of 'which lpr' in the command line? – rleelr Jun 03 '15 at 14:50
  • I made sure it was the same one, which lpr shows it at /usr/bin/lpr – Brian McCarthy Jun 03 '15 at 15:27
  • When I test the print command from the command line it is actually, "lpr .jpg", but from python it is actually a tmp file (from a tempFile.NamedTemporaryFile(delete=False) call. There is no extension so it is simply, "lpr tmpnzt4mE". Could that have any affect. I can't check until I get home. – Brian McCarthy Jun 03 '15 at 17:39
