Printer support is included in our OS image, you can attach PCL printers through serial, USB, bluetooth, IrDA or network. But there's no simple GUI to configure the printer, and none of the OS tools have a printing feature. Here's some links to more information:

We tested it with an HP LaserJet M2727nf over USB.
For sample code how to use a printer see this external site. You can find small demo in our SourceCode examples (VB_PrintTest.zip). The demo is based on the code form the site above.
There are also 3rd party companies who provide printing solution for wince. So far we did no tests with 3rd party SW.
