- This program makes customized graph paper on HP Laserjet++
- compatible printers. Interestingly, the Online! catalog
- features a similar program for (hahaha) dot matrix printers.
- Their program features a friendly user-interface.
- This program is free. So there.
-
- Syntax:
-
- GRIDMAKR thick thin xfreq xbarf [yfreq [ybarf]]
-
- Most arguments are expressed in 1/720 inch.
-
- Arguments in brackets are optional, don't type the brackets.
-
- thick Thickness of thick line
- thin Thickness of thin line
- xfreq Distance between vertical lines
- xbar Draw a thick vertical bar every so many lines
- yfreq Distance between horizontal lines, optional, defaults to x
- ybarf Draw a thick horizontal bar every so many lines, see above
-
- GRIDMAKR writes to standard output. My printer is on parallel
- port 2, so I redirect like so:
-
- GRIDMAKR 10 1 90 8 >lpt2
-
- That command would produce 1/8th inch squares with thick lines every inch.
-
- Here's another interesting one:
-
- GRIDMAKR 1 1 25 0 >lpt2
-
- Look at it for a long time, then take some aspirin.
-
- Graphs should commence printing in a few seconds. You'll notice
- some lines may be thicker than others. I think this is due to
- the 720/inch --> 300/inch translation that the printer does, but
- don't quote me on that.
-
- A note to budding C programmers:
-
- This is a very simple program. It illustrates the usage of these
- laser printer commands: Locate Cursor, Push and Pop Cursor,
- Rules (boxes) and Macros. See if you can add these features:
-
- A user interface - for example, prompts for arguments.
-
- A way of reducing the output to the laser printer.
- (there are several).
