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?
