IMPORTANT: This article contains information about editing the registry. Before you edit the registry, make sure you understand how to restore it if a problem occurs. For information about how to do this, view the "Restoring Registry Key" Help topic in Regedit.exe or the "Restoring a Registry Key" Help topic in Regedt32.exe.

SUMMARY

Windows NT supplies a command line utility (Lpr.exe) and the LPR port print monitor (Lprmon.dll) to print jobs to an LPD service running on another computer. If the remote computer runs SunOS 4.1 or a prior version, you may need to configure LPR to support the SunOS compatibility mode.

MORE INFORMATION

• The lpr -x option allows you to set the SunOS 4.1.x compatibility mode (see lpr -? ).
• When you use an LPR port printer queue, the LPR port print monitor checks the OldSunCompatibility registry value to check if this mode must be enabled (1 enable, 0 disable ).

WARNING: Using Registry Editor incorrectly can cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk.

For information about how to edit the registry, view the "Changing Keys And Values" Help topic in Registry Editor (Regedit.exe) or the "Add and Delete Information in the Registry" and "Edit Registry Data" Help topic in Regedt32.exe. Note that you should back up the registry before you edit it.
