    This class defines protocol for simple text prinitng on an HP Laserjet 2/3

    (and compatible) printer. 

    It does not support multiple fonts, but knows how to print bold, italic etc.

    Graphics printing is not supported - you need a postscriptprinter for this.

    Notice: 

        This class only defines some minimum protocol for printing on

        HP-LJ - you really should use a PostscriptPrinter ...

        ... however, if you own a LJ, here is some class to start with.

        It may need to be enhanced at some places (for example: provide more

        fonts/emphasis's, better international character translation,

        image printing etc.)

    [Disclaimer:]    

        This class is not officially supported - take it or leave it.

    [author:]
