AMAX Printing
It is true that the Epson emulation is compressed unless you print at the
medium quality resolution.
The Mac OS will print a postscript file to disk if you invoke a command
key qualifier when opening the Print dialog (make sure you have selected
the LaserWriter in your Chooser). (Unfortunately, the exact key sequence
escapes me at this moment. Sorry! :^(
I think the combination is either option-K, option-P, Shift-command-P, or
Shift-Command-K. (If you're using 7.x, then I think the finder shortcuts
list the exact key sequence.)
Another option is to take the Tax software & data to a real Mac and print
it from there.
Good luck,
Erik Flom
