116 Reference GuideStartup Guide
If an infrared printer doesn’t print
• Make sure the line between the two infrared ports is not blocked, and that the ports
face each other as squarely as possible. (The computer’s infrared port is on its right
side, beneath the volume control.) The ports should be no more than 1 meter apart.
• Make sure the printer is on and has paper in it.
• Check for printer errors.
• Make sure Windows is running; otherwise infrared printing is not available.
• See “Infrared Problems” on page 104.
