Batch Script Help Needed

Posted on 2010-09-23

I am trying to run a command using a Batch file script to change a printer name if it exists.  Here's the rundown of the PseudoCode I am trying to accomplish.

If "Zebra LP2844" Printer name exists
  Change printer name to ComputerName_LP2844
Else
   END/Do Nothing

Now the command to change the printer name is:
     rundll32 PrintuUI.DLL,PrintUIEntry /XS /n "Zebra LP2844" PrinterName "%COMPUTERNAME%_LP2844"

This however assumes there is a printer specifically named "Zebra LP2844" otherwise it gives an error, which is something I need it to not do.  I thought an IF statement would be best but a try catch would be fine to handle the error, it doesn't matter so long as the end user never sees the error and the printer name is changed if it is incorrect.  Thanks.

You cannot do what you want. Because you pass the printername to rundll, the error is thrown by rundll, i think as a messagebox. You cannnot hide that from commandline

This script will query for installed printers and rename the one that matches OLD_PRINTER_NAME to the value of NEW_PRINTER_NAME
@ECHO OFF
SETLOCAL

SET OLD_PRINTER_NAME="Zebra LP2844"
SET NEW_PRINTER_NAME="%COMPUTERNAME%_LP2844"

SET REGPATH=HKLM\System\CurrentControlSet\Control\Print\Printers

FOR /F "tokens=6* delims=\" %%A in ('reg query %REGPATH%') DO (
	IF "%%B" EQU %OLD_PRINTER_NAME% (
		rundll32 PrintuUI.DLL,PrintUIEntry /XS /n %OLD_PRINTER_NAME% PrinterName %NEW_PRINTER_NAME%
	)
)

ENDLOCAL
