SUMMARY
The following Registry entries can be used to configure printing through LPR/LPD in Windows NT version 3.51:


 * LPR Print Monitor
 * LPDSVC



LPR Print Monitor
One parameter under:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Print\Monitors\ LPR Port\Ports\

PrintSwitch: REG_SZ

This specifies the format control character that the LPR Print Monitor should send to the print server through the control file. By default, this parameter doesn't exist in the Registry, and "l" (lowercase L) is sent as the control character. This can be set to any string. If set, the first letter of the string is taken (the rest of the string is ignored) as the format control character and sent to the print server. Some situations may need 'f' to be used instead of 'l', and this parameter can then be used.

LPDSVC
Three parameters under:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\LPDSVC\Parameters

AllowJobRemoval: REG_DWORD: 0x1

Setting this parameter to 0 disables job removal (that is, once submitted, the job cannot be removed using LPRM, no matter who submitted it originally). If for any reason it is required that LPDSVC not delete a job from the queue once submitted, this parameter should be set to 0. Default is 1 (that is, allow a job to be removed--if request to remove is from the computer that submitted it originally).

AllowPrinterResume: REG_DWORD: 0x1

If a printer is paused, by default anyone can cause it to be resumed by sending the appropriate LPR command. If this parameter is set to 0, request from anyone to resume printer is ignored. Default is 1 (that is, honor any request to resume printing).

MaxConcurrentUsers: REG_DWORD: 0x64

This parameter specifies how many users can concurrently send a job to LPDSVC. Default is 100.
