To doit() method is called three times, each time with a different variant of textprinter Document instance.
A textprinter document has only three basic methods: write(), writeln() and endDoc().
Simple text formatting can be done by using escape sequences (as in the example) or by using the formatting methods setCpi(), setBold(), setItalic(), ...
write() may not be used to print several lines. Text that is longer than the document's lineWidth() will be cut off. This is usually what happens if you print too much text to a line of a physical text printer.

- syscon now creates an automatic Application (13.08.06) — I invented a trick to have the textprinter1.py example work without needing to create an Application but still supporting a --batch or -b command line option.
- Updated textprinter1.py example (11.08.06) — I adapted textprinter1.py because TextPrinters now use Session.debug() (11.08.06).
