- |You probably have the scaleable font in your system or your NTR. I don't see
- |how you can print smooth font if you have ONLY the bitmap and you do not have
- |the scaleable font in your NTR.
-
- |For the LS, if you have TrueType fonts, they will be smooth at any size. Why
- |not? TrueType is scaleable. Correct me if I am wrong.
-
- Both psotscript and quickdraw are scaleable graphics systems, and since the
- advent of ATM fonts and Truetype fonts they both have scaleable fonts. A
- nonpostscript printer with the same resolution can print quickdraw as well as
- a postscript printer (the vast bulk of work done on Macintoshs), however
- there are some special effects in postscript especially in the area of
- altered text (stretches deformations etc.) and grayscaling where postscript
- is superior, and of course for programs like Illustrator, which use
- postscript drawing commands, you need a postscript printer or special
- software. In addition most postscript printers have Appletalk built in
- whereas most non postscript don't (or its an option) and most postscript
- printers are a lot faster. By the way, for most bit map fonts the apple
- postscript printers will substitute a postscript font when printing so you
- will have a smooth font, also if you have substitute font turned off and a 4X
- font it can use the larger font to get resonable output, much like the
- Imagewriters did with 2X and 3X fonts.
- Just my 2 cents worth
