Print Commands and the Compatibility Package

You can still use many SunOS release 4.x print commands if the system is running the SunOS/BSD Source Compatibility Package. Compatibility mode uses SunOS release 4.x command names as an interface to underlying Solaris 2.6 LP print services and does not actually run them the way a SunOS release 4.x system would. When a user types SunOS release 4.x commands to set up printing or to print files from a Solaris 2.6 system, the commands create message files that are handled by the SunOS release 5.6 LP print service scheduler.

Solaris 2.6 printing provides additional capabilities not available in SunOS release 4.x systems. These capabilities enable you to control forms, print wheels, and interface programs, and to set up network print services.
