	PRO8510.COM is a simple assembly language program which will
	activate the various features of the C. Itoh Prowriter, Model
	8510, printer.  It might also work with the NEC 8023/8025,
	the DMP-85, the PMC-8510, and the TEC 8500R.  These all use
	codes which are similar to the C.Itoh but I do not have access
	to any of them for testing.

	The program is invoked at the CP/M prompt by typing:

			    d:PRO8510

	where d: is the drive designation.  A menu will be presented;
	simply press the key which corresponds to the feature
	you want.  The menu will re-appear to allow you to choose
	any additional features.  For example, assume you want
	the printer to print in elite with double strike.  At the
	first appearance of the menu, press <2> to set elite; at
	the second appearance of the menu, press <4> to turn double
	strike on.  At the third appearance of the menu, press <E>
	to return to CP/M with the printer set to print in elite
	double-strike.

	Pressing <0> allows the setting of the left margin.  This is
	handy for listing BASIC programs or other documents where you
	need some room to punch binder holes in the paper.  After
	pressing <0>, the program will ask for the left margin. The
	printer codes as designed by the manufacturer require that
	this MUST be a three digit number.  Examples:

 	    Desired Margin             Number to be typed
	-------------------------------------------------------
		   0				000
		   5	   			005
		  10				010
		  25	 			025
		  50				050
	-------------------------------------------------------

	You should also set the pitch (elite, pica, or compresed)
	and turn elongated mode on or off BEFORE setting the margin.

	Pressing <T> at the menu will cause the word "TEST" to be
	printed so that you can see if the results are what you wanted.
