??? Why aren't you using a simple Postscript driver, such as one of
the Apple Laserwriter drivers, and letting HylaFAX and Sam Leffler's
TIFF libraries cope with it? Many of Microsoft's print drivers are
apparently pretty broken, a frequent source of difficulty for HylaFAX.
And Sam *WROTE* TIFF. Let *HIS* program deal with the transformation on
the HylaFAX server.

Sigh: It seems from this that you are suffering, badly, from the bit
errors of digitizing/scaling/re-digitizing/scaling/etc. And I think
you're right: many TIFF programs seem to have no clue that the pixels
don't have to be square.

Skip this altogether. Stay in simple Postscript on your PC, which
describes *OBJECTS*, and have HylaFAX and ps2fax turn it into tiffg3
just before transmission using WHFC or some other technique to get
it to a HylaFAX server.

Even though your faxes may look a lot better, just because of the higher
resolution....

I hope the points I made help you...
