WiFi PDA Meets Linux--Part 2 - page 5
The workaround for printing a regular Word file is pretty simple. Copy the .doc file to the iPAQ, open it in Pocket Word and then immediately save it as a Pocket Word document. Close out the Pocket Word application and print the file using the tap and hold technique. You can use the same process with Excel files.
Be careful with printing Pocket Excel files, because if the formatting is a little off, you may end up with a few sheets of numbers and a whole bunch of blank sheets. You might have to log into the CUPS machine and kill the job with the lprm command. Then power cycle the printer to clear out it's page wasting behavior.
Also, printing a Pocket Excel file seemed to take a long time. No doubt the iPAQ is processing it's little heart out, to make it happen.
