13. Is it connected? The printer test prints,
but it won't go on line... Well, is the cable from the printer to
the computer connected. Screw down the DB-25 connector at the computer
end and clip the Centronics connector at the printer end (your printer
and computer may have different connectors; e.g., USB). Push-in
and wiggle the connectors.
14. Is it connected to the printer port? Some
SCSI (Small Computer System Interface) are physically identical to the
male DB-25 connectors used for standard IBM/IBM-compatible printer ports. Plugging
a printer into a SCSI port can damage the SCSI host board and the printer.
15. Do you have the correct cable? Many
printers now require an IEEE 1284 and Bi-Directional. USB cables
shouldn't be longer than 15 feet.
16. Is the cable good? Check for bent
pins. Try another cable.
17. Is it connected properly? Screw
the PC end down and latch the Centronics end at the printer.
18. Is there something else connected to the
printer port? Disconnect it and uninstall the device drivers
19. Does the printer port have a software security
device on it? These devices attach to the printer port and
the printer cable attaches to the device. They can break. Try
printing without it.
