DOCUMENT:Q126561 06-FEB-2002 [winnt] TITLE :Printing To An LPR Printer May Be Slow PRODUCT :Microsoft Windows NT PROD/VER::3.5 OPER/SYS: KEYWORDS: ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Windows NT Workstation version 3.5 - Microsoft Windows NT Server version 3.5 ------------------------------------------------------------------------------- SYMPTOMS ======== It takes longer to print to an LPR printer over TCP from an NT Workstation that it does from a mini-computer. CAUSE ===== Windows NT uses delays in the conversation with the printer for compatibility with older versions of SunOS. RESOLUTION ---------- In Windows NT version 3.51, the delay feature is off by default. You can use the following registry parameter to enable the delays: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Print\ Monitors\LPR Port\Ports\\Timeouts OldSunCompatibility : REG_DWORD : 1 By default, the parameter is missing and the system uses 0 (no delay). STATUS ------ Microsoft has confirmed this to be a problem in Windows NT version 3.5. This problem was corrected in Windows NT version 3.51.
