I found our Dell laser to be an easy install once you found on the
Dell drivers page it was really a re-badged Xerox Phaser 6000 :-)

Also cannot dispute that most printers these days work well in most
flavours of Linux, what I was commenting on was places selling these
devices starting to list Linux as being supported along with Windows
and MacOS. Recently installed a Brother inkjet multi-function on Mac
and it was no different from an install on Linux, a bit of additional
tweaking to get the scanner side functional but curiously needed a
re-boot for printer to be recognised after the driver install was done
( Apple instructions didn't say this was required which wasted half an
hour of 'we need to download an Apple driver' followed by 'no driver
available please try later' ). Re-boot was in desperation and really
not expected !
