Sorry, I do not have this setup to test but you could always try HP.COM and their Chat button there.
Greetings,
G4 iMac OSX 10.5.8. I cannot seem to get a multiple page scan to produce one pdf...instead of separate ones on my all in one printer. I have done this before on the same printer/scanner but for whatever reason it will no longer scan multiples to one. The only thing that's changed is I have a new Comcast modem instead of the old ActionTec. There's no place to set a scanner preference for multiples that I can find...in case it's a setting causing the issue. Thanks and I appreciate any help on this.
