Adds improved compatibility for recent OS X versions
Following a recent update for Epson, Canon and Lexmark printers and all-in-ones (AIOs), Apple on Thursday issued an update for most supported HP printers running under Snow Leopard (OS X 10.6), Lion (10.7) and Mountain Lion (10.8). The new combination update for the HP line is 473.4MB in size, though most users will receive the update through Software Update which will be specific for the printer(s) they currently use.
Most, but not all, of the updated drivers are now at version 18.4. The entire Business Inkjet line was updated, as were most of the Color Laserjet models. Only a handful of Designjet models were updated, and the Deskjet line was skipped in this update entirely. A number of Laserjet and both supported Mopier models were updated, while the Officejet line was largely ignored, except for the HP Officejet Pro 8000 Enterprise A811a. The Photosmart and PSC models were also not updated in this release.
Owners who have one of the affected models in their printer list will see the update for those models through normal Software Update or Mac App Store notifications. In Mountain Lion, the Mac App Store functions as the Software Update delivery mechanism. A full list of the updated HP printers can be seen here.
