What kind of printer do you use?

I'm afraid that only old printers with pins is able to do that.

If you have such one, you can bypass the printing system and sends your 
characters directly to /dev/lp0.

Draw.Begin(Printer) ... Draw.End actually generates a postscript file that is 
sent then to the printing system. Only him knows how to transform the ps file 
into something that the printer will understand, how to send the data to the 
printer, and on which device.
