Solaris Transition Guide

Print Commands and the Compatibility Package

You can still use many SunOS release 4 print commands if the system is running the SunOS/BSD Source Compatibility Package. Compatibility mode uses SunOS release 4 command names as an interface to underlying Solaris 7 LP print services and does not actually run them the way a SunOS release 4 system would. When a user types SunOS release 4 commands to set up printing or to print files from a Solaris 7 system, the commands create message files that are handled by the SunOS release 5.7 LP print service scheduler.

Solaris 7 printing provides additional capabilities not available in SunOS release 4 systems. These capabilities enable you to control forms, print wheels, and interface programs, and to set up network print services.
