54 Parallel Error An IEEE 1284 protocol error is detected on the
parallel host interface, or due to a faulty cable.

interface errors for the associated port is
suppressed until the interface parameters are
changed, or the printer is powered off.

processing the print job. The job may not print
correctly. Verify that the correct cable is used. If
a serial error has occurred, be sure the serial
interface parameters (protocol, baud, parity and
data bits) are set correctly on the printer and
the host computer. If a parallel error has
occurred, check the cable connection between
the host and printer.

has occurred. If bit 14 is on, an overrun error
has occurred. If bit 13 is on, a parity error has
occurred.
