I have a HP Officejet 7210 printer/scanner. I used to use Preview to scan, using
File/Import from scanner. However, since upgrading to Mountain Lion, the option is greyed out.
Previously, the option had a sub menu where I had to select 'Include Networked Devices'. Afterwards, the printer, which is connected via Ethernet, showed up and I could scan. Now, there is no submenu anymore.
Image Capture also says no scanners are connected, and going through printers/scanners in preferences and clicking 'open scanner' shows a dialog with the 'scan' button greyed out.
Does anyone know how I can make HP Officejet 7210 scanning work again, either with Preview, or with some other software?
