Hi marcbryant
You can either investigate getting a current printer to work with ye olde OS/2 drivers...
Hi marcbryant,
To expand on Pete's first suggestion, you can do this by downloading the latest drivers, "act" as if you are installing a printer, select the new driver to install, and see the list of available printers it will allow... or look in the readme for each (if it comes with one) to find the list.
As Pete said though, (for newer printers) a postscript printer, or one supported by CUPS is your best bet. Ensure you verify that your printer is not just supported, but that if there are any caveats to that support, they are ones you do not care about (ie: "Epson NewfangledPrint 2000: does not yet print properly if super-glossy card stock selected... use regular glossy card stock mode instead").
For a laser, the Lexmark c500 series (where supporting either (a) native postscript, or (b) an OS/2 driver) are nice color lasers, can do duplexing (check model) and come with network support (some with OS/2 network support and drivers in the box). Most HP postscript lasers (color or BW) seem to work well, and many HP PCL5/6 printers seem to work with various older-model HP PCL drivers.
