/*  Printer.c
 *	Simple screen printing functions for FRACTINT
 *	By Matt Saucier CIS: [72371,3101]      7/2/89
 *	"True-to-the-spirit" of FRACTINT, this code makes few checks that you
 *	have specified a valid resolution for the printer (just in case yours
 *	has more dots/line than the Standard HP and IBM/EPSON,
 *	(eg, Wide Carriage, etc.))
 *
 *	PostScript support by Scott Taylor [72401,410] / (DGWM18A)   10/8/90
 *	For PostScript, use 'printer=PostScript/resolution' where resolution
 *	is ANY NUMBER between 10 and 600. Common values: 300,150,100,75.
 *	Default resolution for PostScript is 150 pixels/inch.
 *	At 200 DPI, a fractal that is 640x480 prints as a 3.2"x2.4" picture.
 *	PostScript printer names:
 *
 *	PostScript/PS			= Portrait printing
 *	PostScriptH/PostScriptL/PSH/PSL = Landscape printing
 *
 *	This code supports printers attached to a LPTx (1-3) parallel port.
 *	It also now supports serial printers AFTER THEY ARE CONFIGURED AND
 *	WORKING WITH THE DOS MODE COMMAND, eg. MODE COM1:9600,n,8,1 (for HP)
 *	(NOW you can also configure the serial port with the comport= command)
 *	Printing calls are made directly to the BIOS for DOS can't handle fast
 *	transfer of data to the HP.  (Or maybe visa-versa, HP can't handle the
 *	slow transfer of data from DOS)
 *
 *	I just added direct port access for COM1 and COM2 **ONLY**. This method
 *	does a little more testing than BIOS, and may work (especially on
 *	serial printer sharing devices) where the old method doesn't. I noticed
 *	maybe a 5% speed increase at 9600 baud. These are selected in the
 *	printer=.../.../31 for COM1 or 32 for COM2.
 *
 *	I also added direct parallel port access for LPT1 and LPT2 **ONLY**.
 *	This toggles the "INIT" line of the parallel port to reset the printer
 *	for each print session. It will also WAIT for a error / out of paper /
 *	not selected condition instead of quitting with an error.
 *
 *	Supported Printers:	Tested Ok:
 *	 HP LaserJet
 *	    LJ+,LJII		 MDS
 *	 Toshiba PageLaser	 MDS (Set FRACTINT to use HP)
 *	 IBM Graphics		 MDS
 *	 EPSON
 *	    Models?		 Untested.
 *	 IBM LaserPrinter
 *	    with PostScript	 SWT
 *	 HP Plotter		 SWT
 *
 *	Future support to include OKI 20 (color) printer, and just about
 *	any printer you request.
 *
 *	Future modifications to include a more flexible, standard interface
 *	with the surrounding program, for easier portability to other
 *	programs.
 *
 * PostScript Styles:
 *  0  Dot
 *  1  Dot*	       [Smoother]
 *  2  Inverted Dot
 *  3  Ring
 *  4  Inverted Ring
 *  5  Triangle        [45-45-90]
 *  6  Triangle*       [30-75-75]
 *  7  Grid
 *  8  Diamond
 *  9  Line
 * 10  Microwaves
 * 11  Ellipse
 * 12  RoundBox
 * 13  Custom
 * 14  Star
 * 15  Random
 * 16  Line*	       [Not much different]
 *
 *  *  Alternate style

	       my machine.  There are two sources of error in getting colors
	       to come out right.
	       1) Must match some dacbox values to the 330 PaintJet dithered
		  colors so that they look the same.  For this we use HP's
		  color values in printera.asm and modify by gamma separately
		  for each of red/green/blue.  This mapping is ok if the
		  preview shown on screen is a fairly close match to what
		  gets printed. The defaults are what work for me.
	       2) Must find nearest color in HP palette to each color in
		  current image. For this we use Lee Crocker's least sum of
		  differences squared approach, modified to spread the
		  values using gamma 1.7.  This mods was arrived at by
		  trial and error, just because it improves the mapping.
