I'm trying to automate some of our printing. The command has been issued from PowerShell or cmd.exe shell correctly. Below I have PowerShell version then cmd.exe version.

lpr -S '192.168.8.200' -Pfiletype=RPS -ol "C:\Users\rburnside\Desktop\Print Test\Hello 2020.09.23.ps"

lpr -S 192.168.8.200 -Pfiletype=RPS -ol "C:\Users\rburnside\Desktop\Print Test\Hello 2020.09.23.ps"

When I try to run it via Python 3 it returns an error code 1. I've tinkered with this for about 3 hours. I've tried using the system(command) function but I'm not sure which shell it uses? I assume cmd.exe. I've verified the command for both PowerShell and cmd.exe is correct and tried both.

Here is my Python attempt:

system("lpr -S '192.168.8.200' -Pfiletype=RPS -ol \"C:\\Users\\rburnside\\Desktop\\Print Test\\Hello 2020.09.23.ps\"")

I've also tried:

system("lpr -S 192.168.8.200 -Pfiletype=RPS -ol \"C:\\Users\\rburnside\\Desktop\\Print Test\\Hello 2020.09.23.ps\"")

I'm at a loss here...

Thanks for your help.

  • Actually lpr IS available in Windows 10 when you enable print services. You'll see it once you do. It's a DOS era command they've kept around. [link](https://learn.microsoft.com/en-us/windows-server/administration/windows-commands/lpr) – Ryan Burnside Sep 23 '20 at 20:56

So it turns out that this can also be done via the COPY command. I've adopted that for my Post Script printing needs instead.

Our server is "joe" and our printer is named "Ricoh-A" on the network. The following command seems to be working much better.

COPY "path\to\my\postscript\file.ps" "\\joe\Ricoh-A"

That was successfully called from Python once I escaped the string backslashes. I'm going to use this for now.
