Deskjet 4180 & Win Vista 6.0 SP2

I have a Deskjet 4180 on an Acer PC running Vista 6.0 SP2. Every time I
awaken my computer from hibernation or sleep, my computer re-installs my
printer. It creates another printer name - HP Deskjet 4100 series (copy N),
and makes it my default printer. It does not delete any other printers; but
does disconnect the previous default printer (HP Deskjet 4200 series (copy
N-1)). When I restart or shut down & reboot, the same thing happens.

Anyone else seen this problem or have any solution?

Thanks,
Chester
