SYMPTOMS

When you use the Windows NT 4.0 Line Printer Daemon (LPD) utility (in conjunction with the print spooler) to process text-stream print jobs, both line feed (LF) and carriage return (CR) characters are translated to a carriage return/line feed (CR/LF) character before the print job is sent to the print device.

MORE INFORMATION

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 topics in Regedt32.exe. Note that you should back up the registry before you edit it. If you are running Windows NT, you should also update your Emergency Repair Disk (ERD).

Although this is the default behavior, you can change it to disable CR/LF processing or to disable CR processing. After you install the hotfix on the print server, use the following steps to configure the print spooler on a per-printer basis for either print processing preference:

To Disable CR/LF Processing

  1. Start Registry Editor (Regedt32.exe).


  2. Locate the following key in the registry


    3. HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Print\Printers\printername\PrinterDriverData
    where printername is the printer to be configured.

  3. On the Edit menu, click Add Value, and then add the following registry value:


    4. Value Name: Winprint_TextNoTranslation
    Data Type: REG_DWORD
    Value: 1
  4. Quit Registry Editor.


  5. Click Start, point to Settings, click Control Panel, and then double-click Services.


  6. Click the TCP/IP Print Server service, and then click Stop.


  7. Click the Spooler service, and then click Stop.


  8. After the Spooler service has stopped, click Start.


  9. Click the TCP/IP Print Server service, and then click Start.


To Disable Only CR Processing

  1. Start Registry Editor (Regedt32.exe).


  2. Locate the following key in the registry


    3. HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Print\Printers\printername\PrinterDriverData
    where printername is the printer to be configured.

  3. On the Edit menu, click Add Value, and then add the following registry value:


    4. Value Name: Winprint_TextNoCRTranslation
    Data Type: REG_DWORD
    Value: 1
  4. Quit Registry Editor.


  5. Click Start, point to Settings, click Control Panel, and then double-click Services.


  6. Click the TCP/IP Print Server service, and then click Stop.


  7. Click the Spooler service, and then click Stop.


  8. After the Spooler service has stopped, click Start.


  9. Click the TCP/IP Print Server service, and then click Start.


When the LPD service is configured with the SimulatePassThrough setting, the job data type is always RAW. Therefore, the print processor settings are ignored.
