You can print files that reside on your handheld PC by:
connecting to a printer equipped with a serial port using the
auto-sync cable.
sending files through the IR port to an IR-equipped printer.
transferring files to a Windows CE–equipped computer and
printing from the computer.
When printing from the computer, Microsoft
application files are printed using the print defaults
established in the computer version of the application.
Your handheld device can print the following kinds of
information:
Pocket Word and Pocket Excel files
Contacts and Tasks lists
A view of your schedule or agenda in Calendar
Inbox messages
Before printing, follow these guidelines:
Connect the printer to the handheld PC via a serial connector
only. Do not connect to a printer parallel port.
Use a 9-to-25 pin adapter, if required by the printer's serial
port.
Do not connect to the printer using a null modem cable.
Ensure that the printer's configuration parameters (speed, data
bits, stop bits, and parity) match those set in your handheld
device.
