| Redirect output of the print operator to paper. Particularly useful if | |
| you're trying to extract information from a printer, but you don't have | |
| access to the data the printer returns to the host. | |
| For example, | |
| FontDirectory {pop ==} forall | |
| names all the fonts registered in the FontDirectory dictionary. Simple, | |
| but only if you can read the data returned to the host by the printer. | |
