Network scanner

[Matthew Saltzman]

I have an HP OfficeJet Pro 8600 all-in-one printer/scanner/fax/copier.
I have no trouble getting CUPS to print to it, but I'm having trouble
getting xsane to find it.  I have the hplip drivers installed, but I'm
not sure what has to be configured in xsane to get it to recognize it as
a network scanner (as opposed to USB).

Does anyone have this or a similar unit working who could provide a
step-by-step guide?

Thanks.
