The win32prn project is designed to use Microsoft Windows 2000 printer drivers on the IBM OS/2 platform family with the use of the ODIN emulation technology. Theoretically, every Windows Driver Model (WDM) 1.1 compliant printer driver could be used with this project. This includes Windows2000, WindowsXP, Windows2003 and WindowME device drivers. has agreed with Vitaliy Tymchyshyn (the developer of the tool) to assist in the hardware compatibility testing for this exciting project, which could eventually become a great alternative for the problem of lack of OS/2 drivers for the new printers.

List of the tested printers includes (note that it should work on many others, so please try and report about both successes and failures):

Device Build ODIN Build Driver Info Comments
Canon LBP-810 0.9.3b CAPT
Epson EPL-N2050/PS+ 0.9.3b 3.31
Hewlett Packard LaserJet 1100 0.9.3b UNIDRV/WinXP UNIDRV means driver supplied with OS Windows.

Note about Win32Prn

At the moment, the project is in public beta stage and is freeware. Project files are time limited (30 days after build) and must be updated after this term.


To set up printer under WIN32PRN one must first set it up under native OS. That's why to use the project one need OS Microsoft Windows 2000 set up and running.

Also to load PE executables and provide required envirinment in OS IBM OS/2 project ODIN is used. It is recommended to use last ODIN version. In case you've faced problems to make a bug report you will need a debug version of the ODIN (to create necessary log files).

Features and limitations

At ideal state this project must run any Windows 2000 printer driver (and Windows XP too, but this possibility is not tested yet). At current moment this is limited by nonideal emulation of the printing subsystem of the WIN32PRN project (this is what author is working at) and nonideal emulation of the OS Windows by the ODIN project (and this is harder to fix). Not only black and white printing is supported (but on the color printers too).

List of known problems includes:

  • Black border output during printing from some applications
