Is it possible to obtain a driver for an iMac computer (Leopard OS) for the Easypen G6 please? David

link to driver

disconnect usb, delete all old attempts, do not connect untill prompted by install

Unfortunately Snow Leopard requires a intel processor to work so the G5 imac will not be able to run the system.

activate virtual xp of win7 and use it within xp

Joao:
The driver for OS X is apparently available on the HP support web site here: (click here)
You'll want the one labelled:
HP Photosmart Studio Includes Support for Mac OS X v10.3, v10.4 and v10.5 (Leopard)

Hello,
Please find here the direct link to your scanners driver and manuals:

Have you used this scanner on Leopard already? I didn't think this scanner was supported.

Do a search on "Leopard". The CanoScan 5000F is not supported in this OS.
