Hi - found this site and installed my hp color laserjet 1600 as described in the install-file.
It prints clear & sharp text, but rubbish images ... colorless, without resolution and with blurred parts.
I shared the printer, and connecting from a windows-box via http://...:631/printers/Color.... it is printing very well.
I noticed the default "monochrome" setting, which was easy
