What are the methods available for downloading or installing the printer driver?

There are four methods: downloading from HP Easy Start at 123.hp.com/laserjet, downloading from the product support website at www.hp.com/support/colorljM553, installing from the printer CD (Windows only), or using the HP Universal Print Driver for IT managed setup via hp.com/go/upd. The default driver for OS X is the Apple AirPrint driver, but a full-featured HP driver is also available. (Page 7)
