I recommend Ross Smith's book a lot for PostScript beginners.  I
especially like the book because it's almost half pictures -- a big
plus in a book about a language designed for graphical imaging.  I am
always bemused by books on graphics that consist primarily of text.

I did however find one very very minor error in the book.  At the
back there is a program for listing the fonts in the font directory
of your printer.  The program assumes that Type 3 fonts must be
downloaded fonts, which is a reasonable assumption.  But the converse
situation is not true -- Type 1, Type 4, Type 5, and so on, fonts can
also be downloaded.  Once a non-Type 3 font is installed, there is as
far as I know, no way to determine if it was downloaded -- apres moi
le deluge.  The program essentially assumes that `Type 3 fonts are
downloaded', which is quite different from the notion that
`downloaded fonts must be Type 3'.  As I said, it's only a minor
problem in an otherwise fine beginner's guide.
