After struggling for months to get the HP Business Inkjet 2800dtn working properly with Mac OS X 10.4, I contacted HP support. I told them the printer is extremely slow and fails to properly print moderately complex images.
Result: They told me they know the 2800 does not work well with Mac OS X. Switch to Windows or get your money back. I'm baffled. I explicitly checked for Mac-compatibility when I bought the printer.
However, the HP website still states that the printer is supported. Isn't this sort of thing illegal?
