-	There is no V1.3 NEC P6 printer driver (not from Commodore).  If you

	       ^^^^^^^^^^^^^
	       Yes, of course.

-	00-01   \003P           set pitch (10 or 12 cpi)
-	02-02   \022            set condensed fine (on or off)
-	03-05   \033W\000       enlarge off
-	06-08   \033ln          set left margin to n
-	09-11   \033Qn          set right margin to n
-	12-12   \015            carriage return
-	13-15   \033U1          set uni-directional mode
-	16-18   \033r0          black text
		^^^^^^
		I checked this one out. It's ESC, r and the ASCII char 0.
-	19-20   \0330           8 lpi spacing

And there's more in what I get:
	21-23   \033r\000       black text again, this time with a null
				instead of the ASCII digit 0.
        24-28   \033 etc...     set graphic mode

I didn't find any patch/zap program, so I couldn't try anything out, but
I suspect the first occurrence of "set black text", since it's a zero
that's getting printed.

-	Perhaps one of these sequences is not valid on your printer.  You might
-be able to use NewZap to look for the sequence:
-
-	"\033P\022\033W\000\033ln\033Qn\015\033U1\033r0\0330"
-
-	and null out any codes which your printer does not understand.  I
-should warn you though that the printer driver fills in fields 1, 2, 8, 11,
-and 15 and will overwrite any value you put there.

Yes, I will look for a patch program to try it out. But it sure loo
like it was something of the normal confusion with printer codes: "Is
this zero a NULL or the digit zero? - we better make two commands each
with one of them!" :-)
