SYMPTOMS
After you apply Service Pack 5 for Windows NT Server 3.51, the TCP/IP printing service no longer interprets the 'o' option correctly. Prior to the release of Service Pack 5, a PostScript file sent to the TCP/IP Print Server with the 'o' option would properly send an already-formatted-as- PostScript file to the printer without formatting the file. After adding SP5, the same command would result either in the file printing the PostScript file as text or result in no output at all.

RFC 1179 states the following:

  7.24 o - Print PostScript output file

+---+--++  | o | file | LF | +---+--++  Command code - 'o'   Operand - File to print

This command prints the data file to be printed, treating the data as standard PostScript input.



CAUSE
Changes in Service Pack 5 disabled the functionality of this option.



RESOLUTION
The current workaround, if the 'o' option is needed, is to revert back to the LPD files prior to Service Pack 5. These files are:

lpdsvc.dll

lprhelp.dll

lprmon.dll

If you need the SP5 files for the added functions they offer, the other workaround, as specified in

ARTICLE-ID: 153666

TITLE : Updated TCP/IP Printing Components for Windows NT 3.51

is to use the 'l' option, instead, to send a PostScript file to the TCP/IP Print server.



STATUS
Microsoft has confirmed this to be a problem in Windows NT version 3.51. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
