Important for all Apple Printing and Graphics Developers:
The information in this Technical Q & A is still relevant up to and including
Mac OS 7.6
with QuickDraw GX 1.1.5. Beginning with the release of Mac OS 8.0,
however, Apple plans to deliver a system which incorporates QuickDraw GX
graphics and typography only. QuickDraw GX printer drivers and GX printing
extensions will not be supported in Mac OS 8.0 or in future Mac OS releases. Apple's
goal is to simplify the user experience of printing by unifying the Macintosh
graphic and printing architectures and standardizing on the classic Printing
Manager.

Q: n my app, I'm creating a page that contains a line of single layer text
shapes, with each word being a different color. The page displays correctly
when it's opened in SimpleText, but shows a bug when it's printed to a
PostScript printer: each line prints with one color instead of each
word being a different color. Any ideas?
A: This is a bug in the GX source code. This bug only occurs with single layer
text shapes that have a nil style in their face layer. There is a workaround.
Do this anytime you do a one layer text face except for italicizing text: this
workaround slows down the italic drawing but speeds up all other cases.
Create a "generic" style object (via GXNewStyle) to replace the nil style. Set
the text size to 1.0 (important) and pen=0 in the style. The other fields are
irrelevant to this fix. The main points are text and pen size. Set your style
to this "generic" style and the problem will disappear.
