Clearing a stuck spool

>I have an HP 2605dn Laserjet printer connected via Ethernet cable to a
>Netgear wireless router that is on a home LAN. Two M/Cs (both with XP+SP2;
>one Pro the other Home) use the printer; the Pro via an Ethernet cable and
>the Home via a wireless connection.
>
> Both have the same problem: if left on overnight, any subsequent printout
> usually gets stuck in the spool - it neither prints nor can be deleted.
> When this happens, the router is still fully operational and both M/C is
> able to access the internet as normal. Recycling the printer has no
> effect, but stopping and restarting the spool usually fixes the problem
> and printout appears fine for the rest of the day, so, to make it as
> painless as possible I wrote a little .cmd file containing the following
> two lines:
> net stop spooler
> net start spooler
> It works fine, except that sometimes it also needs me to right-click on
> the spool icon and hit "refresh". Can anybody tell me how to issue the
> "refresh" command from within my little .cmd file?
