+=head1 FUNCTIONS
+
+=over 4
+
+=item C<print_document %params>
+
+Prints a document by spawning the external command stored in
+C<$self-E<gt>printer_command> and sending content to it.
+
+The caller must provide either the content to send to the printer
+(parameter C<content>) or a name to a file whose content is sent
+verbatim (parameter C<file_name>).
+
+An optional parameter C<copies> can be given to specify the number of
+copies to print. This is done by invoking the print command multiple
+times. The number of copies defaults to 1.
