In an addition to this, i see HP has a "Administraton" Pack that you can download that has a bunch of utilities in it.. one of them lets you Edit the driver package to select the 1200 DPI settings.. BUT.. Even tho i did this, told the driver to Force 1200 DPI, when the driver installs via the HP Package, and the printer does its auto configuration, it sets it back to 600 and still there is no 1200 in the driver options.
$1000 Printer when i bought it (Actually $1300), and cant even use its full capabilities. This is a HORRIBLE job by HP's Driver team.. What a total sham. Should be ashamed that this was over looked. The Laserjet printers are what HP is KNOWN FOR. Comon..
