You can change the default printer spool directory for all
printers or the printer spool directory for specific printers.
To change the default printer spool directory for all printers
add the following value:
HKEY_LOCAL_MACHINE \SYSTEM\CurrentControlSet\Control\Print\Printers
Value Name: DefaultSpoolDirectory
Data Type: REG_SZ
String: full path to printer spool directory
To change the default printer spool directory for specific printers
add the following value:
HKEY_LOCAL_MACHINE \SYSTEM\CurrentControlSet\Control\Print\Printers\<specific
printer>
Value Name: SpoolDirectory
Data Type: REG_SZ
String: full path to printer spool directory
You must make sure that the path specified actually exists. If it does not exist, Windows NT uses the default spool directory.
