The PrintTarget command initiates printing of the Intermediate Code expression ic according to the printing rules previously defined for the module Printer.  PrintTarget returns a string, which corresponds to the translated output.

In most cases, PrintTarget is called by the PrintTarget procedure of the language definition module containing this Printer, perhaps with some pre- or postprocessing.  For example, in a language definition module m, the command m:-PrintTarget may call m:-Printer:-PrintTarget.
