Important This article contains information about modifying the registry.
Before you modify the registry, make sure to back it up and make sure that
you understand how to restore the registry if a problem occurs. For
information about how to back up, restore, and edit the registry, click the

http://support.microsoft.com/default.aspx?kbid=256986
SYMPTOMS
===============
When a formatted job prints from a line printer remote (LPR) client to a
Windows NT computer that is running the Line Printing Daemon (LPD)
services, PCL or PostScript codes are printed instead of a properly
formatted document.
RESOLUTION
================
The LPD service can be reconfigured to ignore the format control command
from the LPR client and always assign the RAW data type. Use one of the
appropriate sections below to reconfigure the LPD service.
Configuring SimulatePassThrough for all printers in Windows XP Professional
and Windows Server 2003
To assign the RAW data type regardless of the control file contents in
Windows XP Professional and in Windows Server 2003, follow these steps.
Warning: If you use Registry Editor incorrectly, you may cause serious
problems that may require you to reinstall your operating system. Microsoft
cannot guarantee that you can solve problems that result from using
Registry Editor incorrectly. Use Registry Editor at your own risk.
1. Start Registry Editor.
2. From the HKEY_LOCAL_MACHINE subtree, click the following subkey:
\SYSTEM\CurrentControlSet\Services\LPDSVC\Parameters
3. On the Edit menu, click New, and then click DWORD Value.
4. Name the new entry SimulatePassThrough.
5. Double-click the SimulatePassThrough entry, and then change the data
value to 1.
Note: The default data value is 0. A 0 data value informs LPD to assign
data types according to the control commands.
6. Click OK.
7. Quit Registry Editor.
Configuring SimulatePassThrough for all printers in Windows NT 4.0 and
Windows 2000
To assign the RAW data type regardless of the control file contents in
Windows NT 4.0 and Windows 2000, do the following:
WARNING: Using Registry Editor incorrectly can cause serious, system- wide
problems that may require you to reinstall Windows NT to correct them.
Microsoft cannot guarantee that any problems resulting from the use of
Registry Editor can be solved. Use this tool at your own risk.
1. Run Registry Editor (REGEDT32.EXE).
2. From the HKEY_LOCAL_MACHINE subtree, go to the following key:
\SYSTEM\CurrentControlSet\Services\LPDSVC\Parameters
3. On the Edit menu, click Add Value.
4. Add the following:
Value Name: SimulatePassThrough
Data Type: REG_DWORD
Data: 1
NOTE: The default value is 0, which informs LPD to assign data types
according to the control commands.
Configuring SimulatePassThrough in Windows NT 3.51
In Windows NT 3.51 the code looks for a registry setting in the LPD key
instead of the LPDSVC key. You can work around this problem by creating an
LPD key at the same level as the LPDSVC key and then duplicating the
information in the LPDSVC key to the LPD key.
For Windows NT 3.51 to assign the RAW data type, regardless of the control
file contents, do the following:
WARNING: Using Registry Editor incorrectly can cause serious, system- wide
problems that may require you to reinstall Windows NT to correct them.
Microsoft cannot guarantee that any problems resulting from the use of
Registry Editor can be solved. Use this tool at your own risk.
1. Run Registry Editor (REGEDT32.EXE).
2. From the HKEY_LOCAL_MACHINE subtree, go to the following key:
\SYSTEM\CurrentControlSet\Services\LPDSVC\Parameters
3. On the Edit menu, click Add Value.
4. Add the following:
Value Name: SimulatePassThrough
Data Type: REG_DWORD
Data: 1
NOTE: The default value is 0, which informs LPD to assign data types
according to the control commands.
5. To work around the problem mentioned above, create an LPD key at the
same level of the LPDSVC key.
6. Click the LPDSVC Key, click Save Key from the Registry menu, and then
save the file as LPDSVC.KEY.
7. Click the LPD key created in step 5.
8. Click Restore on the Registry menu, click the file created in step 6,
and then click OK.
9. A warning message appears. Click OK and then quit Registry Editor.
10. At a command prompt, type:
net stop lpdsvc
11. At a command prompt, type:
net start lpdsvc
MORE INFORMATION
========================
The Windows NT LPD Service follows the RFC1179 specification. This states
that the LPR client must tell the LPD server how to handle the print job.
If the client formats the job, it must send the "l" control character to
instruct the LPD server to print the job without any alteration.
Some LPR clients cannot be configured to send different control characters
and always send an "f". This control character instructs Windows NT to
assign a data type of TEXT and to use the printer driver to create a new
print job that prints the text of the original job on the page. In the case
of a postscript job, the new print job prints the original job's PostScript
code on the page.
