Question

I am porting a C# program to Linux (using Mono). The only compatibility issues that MoMA has found were all related to printing: P/Invokes of functions from winspool.drv:

• ClosePrinter
• EndDocPrinter
• EndPagePrinter
• OpenPrinter
• StartDocPrinter
• StartPagePrinter
• WritePrinter

These are all used in the same class, which prints files (which must be either PDF or PS) by wrapping them in PJL (to set the paper size/tray/orientation) and calling WritePrinter.

I’ll need to rewrite this printing logic with non-Windows-specific code. A previous question refers to System.Drawing.Printing, but it seems to be way too low level. I don’t want DrawString and DrawImage, I want “print this PostScript file”. Is there functionality in Mono to do this?

Answer 1

I ended up using System.Diagnostics.Process to call the lp command.
