Features
The box has the following features:
Compatibility to Digital PPL3 ANSI Protocols
The conversion box with the printer replaces Digital PPL3 printers
without degrading the overall performances.
The box emulates the following DEC PPL3 printers:
DECLaser 1100, DECLaser 2100/2200, DECLaser 3200, LN03 Plus.
Ease-of-use
Simple configuring and operating.
Separate Power Supply
The conversion box is powered via an external AC/DC adapter.
Direct Connection Concept
The conversion box is designed to be connected directly to the parallel
printer port through a bi-directional Nibble 1284 interface and uses a
standard serial interface for the host connection.
Compact Size and Lightweight
Allows a direct connection onto the printer without significantly
increasing the overall printer footprint.
Autosensing capabilities
Can automatically detect whether the type of job being sent to it is
PostScript or DEC PPL3 compatible.
Transparent Mode for Job Control
In this mode, the Convert Box operates in bi-directional
communications without conversion. This operating mode is used in
environments with software applications for job-level printer control
and printer status information.
For instance, this mode applies to the following:
- using the DCPS (DECprint Supervisor) software for printing
PostScript jobs.
- printing under PJL (Printer Job Language) control for PCL or
PostScript jobs
