What is your printer model? What interfaces does it have?
With that s&^%y computer, your only options are to find wireless print server, and **somehow** make it connect to your tablet even in the field (without a router)
Anyway - your employer could spend a little bit more than $179 for a tablet/laptop which will do the job (one wihch has USB interface). With 1gb of ram, and sloppy Atom CPU, it will choke on everything but basic computing tasks (not to talk about cramped keyboard and terrible display). You (or him/her) cannot expect to move a boulder with tooth picks.
