The easiest way to approach this question is for me to ask what printer

Windows CE doesn't really deal with Printer drivers in the sense that you are likely familiar with - there a very small number of exceptions.

The HCL on this site gives you a starting point list - if it's hp and HPC2000 compatible, CE4 should be A-OK provided the PCL layer is installed
