CUPS used to support 1200 DPI on my printer (HP Laserjet P2015DN). Since
Apple took over, the CUPS PPD will only do 600 DPI. I fixed this by
using the MS Windows PPD, which I extracted from the installation CD
that came with the printer.
CUPS updates leave the config alone, so it just keeps working.

Some things just don't work. I use a printer daemon alongside CUPS to
print text (don't install CUPS' BSD LPD emulation). It uses paps to
convert UTF-8 into PS. This way, I can even print plain text hieroglyphs.

Cat Some_File.ps | lpr (bypassing CUPS) should work. If not, it's not a
postscript printer.
