The subject operating systems have LPT1, LPT2, and LPT3 available by default.
You can add additional LPT ports, from LPT4 though LPT9. These new ports will be available in the Add Printer Wizard.
I have scripted AddLPT.bat to make adding of these ports easier.
The syntax for using AddLPT.bat is:
AddLPT from to
where From is the starting port number and To is the ending port number.
Examples:
AddLPT 4 9
AddLPT 4 5
If you previously used AddLPT 4 5, you can now issue
AddLPT 6 9.
AddLPT.bat contains:
@echo off setlocal if \{%2\}==\{\} goto syntax if "%1" LSS "4" goto syntax if "%2" GTR "9" goto syntax set from=%1 set to=%2 @echo REGEDIT4>%temp%\LPT.REG @echo.>>%temp%\LPT.REG @echo \[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Ports\]>>%temp%\LPT.REG for /l %%i in (%from%,1,%to%) do @echo "LPT%%i:"="">>%temp%\LPT.REG @echo.>>%temp%\LPT.REG regedit /s %temp%\LPT.REG net stop spooler net start spooler endlocal goto :EOF :syntax @echo Syntax: AddLPT from to @echo Example: AddLPT 4 9 endlocal
