Can't save scanned images using Preview
Since upgrading to Yosemite 10.3.3 I can no longer save scans from Preview. (Nor edit them either). I've tried uninstalling and reinstalling the computer, using Image Capture instead (can't save from that either). From my research online, it looks like there is an incompatibility with HP printers and the latest Mac OS.
Any help really appreciated here.
MacBook Pro, OS X Mountain Lion (10.8.2)
