Description:

This class defines protocol for simple text printing on an Epson-FX1 printer
(and compatibles, such as FX80, FX100, etc.). 
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.

I cannot tell, if this is really an Epson -
all I had to test was a Citizen 120D - its documentation claims it to be 
FX1 compatible.

Notice: 
    This class only defines some minimum protocol for printing on
    Epsons - you really should use a PostscriptPrinter ...
    ... however, if you own an Epson, 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 etc.)

[Disclaimer:]    
    This class is not officially supported - take it or leave it.

[Disclaimer2:]    
    This is more or less completely outdated (look at the creation date of this class !).
    Left for historic (nostalgic?) reasons.
    Will be removed (or made autoloaded) in the future.
