I have to use HylaFAX to send facsimile messages.
I downloaded the HylaFAX RPM from their Web page.
It insisted that I use ghostscript 5.10 or later.
I downloaded ghostscript 5.50 from its home page.
I am using a HP LaserJet IIIP printer.
The driver that ghostscript 5.50 has for this device is
not named the same as the Printtool drivers.
all needed manual changes to get the printer working again.
Suggestion: have printtool get its print driver names for
the user to select from the "gs -h" output so it will always
match what is actually available.
Unfortunately, printtool needs more than just the driver
names; it needs the options it supports, etc. What
driver that's in 5.5 are you trying to use?
ghostscript-5.5 comes with the ljet3d driver, at least AFAICT
from reading the source, so that shouldn't be a problem.
In any case, printtool does check the output of gs -h when
setting up the printer; however, we can't check if you
configure the printer and *then* change ghostscript.
