	Sounds to me like you are sending the characters through the
printer device's filter.  ie. It is expecting Amiga standard escape
sequences which it translates to escape sequences for the particular
printer selected under preferences.  'ESC[6w' is the proper command
to turn on enlarged (double width) text.

	If you don't want to use the standard Amiga commands, then you'll
have to send the output directly through the parallel or serial port.
(depending on whether you have a parallel or serial printer).  Unfortunately,
I don't know how to do this in Amiga Basic.
