What is the brand of the Handheld.
If the printer is an integrated printer from the same vendor, then there
MUST be an SDK available from the vendor that supports all peripherals
(Printers, Scanners etc).
If not then check if the printer is an OEM and goto the original
manufacturer.
PrinterCE supports specific printers and almost all types of connections
(IR, serial, bluetooth) so if your printer is supported just check the
connection it uses.
