DOCUMENT:Q160273 07-SEP-2001 [winnt] TITLE :LPR 'o' Option Does Not Work After Applying SP5 PRODUCT :Microsoft Windows NT PROD/VER:WinNT:3.51 OPER/SYS: KEYWORDS:kbprint ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Windows NT Workstation version 3.51 - Microsoft Windows NT Server version 3.51 ------------------------------------------------------------------------------- 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: Q153666 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.
