This past week I received a new release of PrintScript (1.0.1), which
the enclosed letter said went out to all registered owners.  This 
release appears to be mainly a bug fix release.  PrintScript is a
Postscript interpreter that runs on the Amiga.

I tried to see if the "preferences" printer driver would now work for
me.  I still got the same error message.  I talked with the folks at
Pixelations, and we discovered that the problem occured when you
have non-zero entries into the width and height limit fields in 
Preferences' Graphic 2 screen.  This is even a problem if you have 
things set to "ignore" these fields.  Pixelations was able to 
reproduce the problem and later find the actual bug.  I would imagine 
this will be fixed in the next release.  Anyway, zeroing these fields 
got the "preferences" drivers to work fine.

Pixelations has fixed a bug in the charpath operator.  This was
apparently the cause for only being able to print outlines of only
a few characters.  Outline fonts worked fine on the tests I ran.

The problem with setting half-toning to screen freq=300 and screen
angle=0 has also gone away.

The problem I had with printing text around a circle turned out to
be a bug in my Postscript program.  I was missing a space between
a set of parentheses -- it is not clear from the book that a space
was supposed to be there.

The imagemask operator has been upgraded.  It no longers ignores
the "invert" parameter.  Thus, it matches how things are displayed
in City Desk.  The imagemask operator still is not complete -- it
simply converts itself into an image operator, which writes on
top of anything already placed in its space.  Keep other items
away, and you'll be okay.

I've also verified that PrintScript can write a file with a 
run-length encoding of the image.  I've been able to get a crude
version of "display Postscript" going by using these files.
