Yes, you need specific drivers for OS2 and if the printer is a WinPrinter, ie dump printer using windows as a printer engine then you won't get it to print from OS2. If it not a win printer you might be more lucky.I would recommend you to take a look at IBM Device Driver Pak, click here. to get there.I don't know how lucky you'll be with the Z32 printer but the Canon you should get to work. Even if you don't find a 100% matching driver you usually can choose the closest matching one.
