SP01 Printing Mulitple Spools

Hi

When printing multiple spools from SP01 the print window appears for each spool and OK has to be clicked or entered for each entry.  How can this be set so that the print window only appears once?

I have tried pasting the spool id in the field spool request number on the output requests tab and selecting the output device 'Local Windows Printer' but the print window still appears for every spool id.

Many thanks
