Step 3: Check the printer connection
Parallel or USB
Make sure your printer is connected directly to the parallel or USB port. Do not
share the port with other devices, such as a Zip drive. Make sure the cable is
connected firmly to the printer and computer.
Infrared
Make sure any necessary software is installed in the host device, for example,
BtPrint for Palm OS PDA users. If you are still having problems, consult the
infrared documentation for the PDA or laptop device.
Tips for infrared connections
Place the infrared-sending device so its infrared lens is within 3 feet
(1 meter) from the printer and within a 30-degree total angle from the
printer’s infrared lens. The printer’s infrared LED turns green when
receiving an infrared transmission.
If the infrared-sending device is moved out of range of the printer’s infrared
lens at any time during the printing process, the printer will stop printing
and await additional data. If you realign the devices quickly, the print job
should resume.
Continue to keep the infrared-sending device aimed at the printer’s infrared
port while the printer is receiving the file. You can move the device away
after the printer’s infrared LED turns off.
Bluetooth
Make sure any necessary software is installed in the host device, for example,
BtPrint for Palm OS PDA users. Make sure your Bluetooth settings are correct.
To do so, you need to connect the printer to the computer via a USB or parallel
cable. Open the Toolbox, click the
Printer Services
tab and then click the
Configure Bluetooth Settings
button. Make sure your Bluetooth settings are
correct. See also
