# Including printer control codes into TeX file

If you employ the a built-in printer driver in printing (box of dviprt is checked in the printing dialog), you can include files containing the printer control codes into TeX files.
The followings are examples of TeX special commands. They would be useful when including draw images written in the LBP page description language.
\special{lipsfile=name} (for LIPS III/IV)
\special{escpagefile=name} (for ESC/Page)
\special{pdlfile=name} (for dviout internal driver)
These commands send the name files ( name.lp3, name.epg, and name.pdl, respectively) directly to the printer. If the file name is not available, the command is ignored. When Previewing, these command are also ignored.
For LIPS III/IV and ESC/Page, these files are printed on the page where these special commands are put in the TeX source.
