Actually the 24 pin output with the LQ1500 looks WORSE.  This is
because the driver uses the single pass mode (only one pass of the
print head over each line) which is 180x180 dpi which is not as good
as the three pass 240x218 dpi mode used with 9pin printers.  The advantage
is three times the speed.  I've used the PC-TeX (actually
Personal TeX, PC-TeX is their TeX program) drivers for both Epson
9-pin and the LQ1500 and the faster speed of the LQ along with
single pass graphic mode makes the LQ1500 print about 6 times the
speed of the MX series.  I've not used any of the newer LQ's (1000,
800 and now 1050 and 850) but they should be even faster.  I gladly
gave up the little bit of quality difference for the speed.  I do
wish there was a single pass 240x240 mode or even 180x240 available
on the printer.
