Canon BJC-55 - Manual (Page 101)

Cannot print via the infrared port
If the print job does not start when using the infrared port, check the
location of the printer in relation to the computer or PDA. Change the
location of the printer so the infrared ports are facing on another at the
correct distance and angle.
The distance and the angle between the infrared ports could differ with
computer model, the PDA capability and the surrounding environment.
Keep the distance within 80 cm and remove any object blocking the
path between the infrared ports. Print data cannot be sent or received if
an object blocks the path between the infrared ports. Start the print job
again.
If you see COMn Write Error or a similar message on the screen, switch
the printer off, switch it on again, then start the print job again. The
correct COM port must be selected for the computer or PDA. (☞33)
