This works well, but puts the load onto the PostScript interpreter.
For tests, short jobs, and personal use, this is fine, but if you
are writing a driver with performance in mind, you should at least
consider doing the job on the host. This is often required anyway,
if you are doing line- or page-breaking, hyphenation, or other
sophisticated typography. If this is what you need, look at the
AFM files, which give character widths (and also provide other
goodies like bounding boxes, kerning info, etc). The format is defined
in technote #5004, and there are a bunch of other technotes on text
setting for a driver, all available from the Adobe File Server.
