I got a new HP laserjet 1020 printer, but was surprised to find out that in the HP website, it said there is no mac driver for this printer. I could not find Laserjet 1020 driver showed up in the printer driver list in my mac either.

I found an easiest way to get this printer work in Mac osX .

All you have to do is just select the driver for HP Laser Jet 1022 model, and viola, it WORKS!

Later, i found that if you download the HP driver package from Apple website: http://support.apple.com/kb/DL907 the HP Laserjet 1020 driver included in the install. But who would go through the job of downloading 550MB just for the driver. Nonetheless, my printer just works just fine with the Laserjet 1022 driver in mac.

Good luck!!
