-NOTE S Rahtz 1998/01/18: renamed files to suite 8+3 <name>.cfg style
-********************************************************************
-
-Release 1.13, 21 Aug 1995
-Release 1.12, 02 Mar 1995
-Release 1.0, 20 Feb 1995
-
-This is a set of files which can be used with dvips to control certain
-parameters of the printer, like simplex/duplex printing, or screen
-frequencies of images.
-
-Put together by Volker Kuhlmann, VOLKER@ELEC.CANTERBURY.AC.NZ.
-No copyright. Freely distributable. If you make additions, please send
-me a copy.
-
-
-LIST OF FILES
-=============
-
-README This file.
-config.* Configuration files and header files for dvips. Special
- format which serves both purposes.
-
-
-INSTALLATION
-============
-
-Copy these files into a directory which is searched by dvips both for
-configuration files and for header files. dvips looks in $TEXCONFIG for
-configuration files, and in $DVIPSHEADERS for header files. For details
-please see the dvips documentation.
-
-
-USAGE
-=====
-
-dvips reads the instructions in a configuration file <configfilename>
-with the -P option:
-
- dvips -P <configfilename>
-
-All these configuration files contain the PostScript code for the
-respective operation as well, and can be used as header file as they are.
-
-Now to the stuff provided:
-
--P simplex On a duplex printer, force printing in simplex mode. On
- a simplex printer, this will be ignored.
--P duplong On a duplex printer, force duplex printing with binding
- on the long edge. On a simplex printer, this will be
- ignored.
--P dupshort On a duplex printer, force duplex printing with binding
- on the short edge. On a simplex printer, this will be
- ignored.
--P a3 Print on A3 paper.
- Note: this is just a demo - use "-t a3" instead!
--P inv Print all pages inverted, i.e. white letters on black
- background.
- Note: this currently does not work properly. Any
- hints/fixes greatly appreciated!
--P screenN Print images with a screen frequency of N lpi at
- 45 degrees.
- N = {70, 80, 85, 90, 100, 110, 120, 130, 140, 150}
--P screen100-0 Print images with a screen frequency of 100lpi
- at 0 degrees.
-
-Note: When working with screen frequencies, it is possible that
- turning the printer off and back on solves the problem of the
- screen commands not having any effect.
-
-
-CONTROLLING SCREEN FREQUENCIES
-==============================
-
-Various PostScript commands for controlling the screen frequencies of
-images exist, but not all work on all printers. See fragments of
-PostScript code and comments below. The form working on most printers is
-
- LPI DEGREES {FUNCTION} setscreen
-
-Insert numbers for LPI and DEGREES, and a function for FUNCTION about
-which I only know (right or wrong?):
-
- "Should read 2 values from the stack (x, y coordinates in a
- halftone cell), and return one in the range -1 to 1. The return
- values determine the order in which pixels within a halftone
- cell are whitened to produce any desired shade of gray."
-
-The simplest function is {pop}, creating a "linescreen" pattern. There
-is also a function "Dot" (currently used) and "Ellipse". For any other
-frequencies/angles/functions put the instructions in a file, and load
-the file with
-
- dvips -h <filename>
-
-Thanks to osakari@unda.fi (Olavi Sakari) for some help, and the "Dot"
-and "Ellipse" code.

-Notes follow:

-% Works on HP LJ3Si, HP LJ4m. Ignored on HP LJ4mv (VK).

-% Ignored on HP LJ4mv (VK).
-
-
-%70 45 {pop} setscreen
-% Produces a funny, 1-diagonal pattern ("linescreen") on HP LJ4mv (VK).
-
