Force windows spool file use jobid as its name

On Windows NT/2000 you will find the files by name XXXX. SPL where XXXX was the jobid returned by the enumjobs API. however, Windows XP/2003 create spool files named fpxxxx. SPL where XXXX is no longer the jobid.

This is the side effect of file pooling, not a bug. you can "turn off" spool file pooling by keeping printed jobs or specify a different spool directory. the workaround to this is as below:
To turn off spool file pooling on a per printer queue-Basis

1. Click Start, click Run, type Regedit in the open box, and then click OK.
2. Locate the following registry subkey, where <printername> is the name of your printer: HKEY_LOCAL_MACHINE/software/Microsoft/Windows NT/CurrentVersion/print/Printers/<printername>
3. In the right pane, right-click spooldirectory, and then click Modify.
4. In the value data box, type the location where you want the spool files to be stored. For example, type C:/Windows/system32/spool/printers as the default location.
5. Quit Registry Editor.
6. Restart the Print Spooler service.

All new jobs will be of the form XXXX. spl xxxx. SHD and will be numbered consistently with their jobids.

Note: This method only works on Windows 2003 Server. This method does not work for Windows XP.
