Section 7: Interface Specifications

7.3 IEEE 1284 PARALLEL INTERFACE

The IEEE 1284 Interface on the printer complies with Centronics/ IEEE1284 standards.It will automatically
detect the IEEE1284 signals and operate in the high speed mode. If it does not detect the IEEE1284 signals,
it will operate in the standard Centronics mode, which is significantly slower. For this reason, an interface
cable and host interface conforming to the IEEE1284 specification must be present to fully utilize the speed
capabilities. Single-item buffer and multi buffer are available for the receive mode, and switchblade in the
Interface Mode of the printer.
The ECP mode is recommended for LPT1 port settings.
Make sure to change the LPT1 port settings through the BIOS settings.
