What is protecting of lines? always wondered.

For the HP4, my HP3 has a green wheel to set the hv which you can adjust
when the lid was open.
But i think all newer printers do that over software only. You should find
it in the printer properties.
My lexmark M412 has the toner density setting there.

Also, i found with HP genuine HP toner is darker than rebuild (the brand i
had at least).
