The LaserJet P4510 printer series are the big boys of the P series. Ranging between US$1,600 and US$2,180 depending on features, the P4510 comes with the security features available on the P4015 plus the addition of the multipurpose paper sorting tray.
Despite HP touting the environmental friendliness of this printer, expect to pay extra for automatic duplex printing.
In case you aren't remotely interested in environmental friendliness, and just want to print to high heaven — the P4015 takes a maximum of 3,600 sheets and has a claimed maximum print speed of 62 ppm.
LaserJet P4510 will be available from 1 May.
Why can't HP release Office Jet Pro L7780 in Australia.

Australia has Officejet L7580 & Officejet L7680 but not the 7780!
