Instead of printing to the printer add an option to direct the output to tempory file
and then call a custom program with the tempory file as the passing parameter.
e.g. send {esc}]4i .... {esc}]5i (normal aux printing.)
Instead of sending it for printing, shelexecute "the_print_program tempory_file_path&name"
with the output save in a tempory file(Random name). (set the_print_program up in the ini file)
