Transient fonts
Transient fonts are downloaded each time a document is
printed, and remain resident only while that document is
being printed. The printing program flushes them from
memory, usually at the end of a document. Transient fonts
allow a huge variety of fonts to be used without filling the
printer’s memory.
Automatically downloading a font takes only 15-20
seconds, so the price of transient fonts is quite low.
Macromedia recommends that you use transient fonts in
most cases. The download time is insignificant when
compared with the problems caused by filling up the
printer’s memory with permanent fonts.
