Simulate printers on AD network

a printer is a "logical" construct and does not have to correspond to a real physical device. You can add, share and publish printers to the directory without having real physical printers. Select LPT1 or File as the port when creating them.

Setup printers and use the FILE port. When you print you will be prompted to save a file somewhere.

There's plenty of things that can simulate printers. You can always make a printer attached to LPT1 on a server and share it out. You could install software like Adobe Acrobat or other PDF "printer" software, assuming you can find one that allows itself to be shared.
