does anyone know how to change the settings of a HP LaserJet 4M+? thank you!?

Answer 1

In Laserjet 4 all the settings can be changed via the front panel. Just hit menu, and then scroll through the choices. Hit OK to pick the category you scrolled to, then scroll through the choices, so on and so forth.

You can find owner's manual on hp.com if you need to know which settings does what, but sounds like you already know what to change.

Answer 2

if you have the software installed that came with the printer just access the software... an alternative would be in the control panel under printers and faxes....
