ENWW Port communication 97
9Port communication
The HP LaserJet 1015 printer includes both an IEEE-1284 (parallel) port and a USB port.
Note Do not connect the printer to the computer using both ports because printing results may be
unpredictable and this configuration is not supported.
Parallel port connections
If you are connecting the HP LaserJet 1015 using the parallel port, then the computer must
include a bidirectional data bus and cable. Ports are designated as enhanced capabilities port
(ECP), IEEE-1284, or PS/2 qualify.
Extended parallel port only (EPP-only) or unidirectional ports are not supported. However, some
ports can be set to EPP/ECP through the CMOS setup or a jumper setting, which is supported.
See Troubleshooting (page 105) in this document for parallel port issues and solutions.
Other parallel port devices
If connecting the HP LaserJet 1015 directly to the computer’s parallel port, then it is recommended
that you do not use devices such as a switch box, security dongle, or other device connected to
the same parallel port. Disconnect such devices prior to connecting and using the HP LaserJet
1015 series printer. Another option would be to have two parallel ports installed in the computer.
Parallel port expansion cards may be used, but they are not supported by Hewlett-Packard.
