Help! Testing printer in my OS :(

[Bender]

Does anyone know of a program like a Virtual Printer that can connect to a Virtual Machine?
My OS can print one letter to a printer, but I need to test it,
When I test it it says 'Printer Busy!', So I think I am going in the right direction
But I still need to test whether it's sending the letter to print to the printer port.
I don't have a real printer :/. So I thought to have a program that can display what letter/byte was sent to the port.
HELP!

Various virtual machines have methods of allowing the guest OS to print.

This page suggests that VMware Workstation can emulate a serial port printer.

VirtualBox, QEMU and Bochs can all emulate a parallel port as a passthrough device. Bochs can also emulate a parallel port that outputs what it recieves to a file (see here); that sounds like what you want. VirtualBox and QEMU may be able to do so as well.
