'PCB & Schematic/Printer output'

If you are using a HP Laserjet printer to print your
HPGL-files you don't have to put them through a program.
The printer can understand HP-GL if you send the appro-
priate control codes.
I have made a pair of batch files to do the job.
Works just fine, I use it for schematics and PCB layout.
Anyone care to try, they can have the files.

When I first used 'printgl' it was to output
to a Canon ink-jet. The Laserjet came later.
Using 'printgl' still has a number of advantages.
First, it can output to an enormous range of
printers from 9- and 24-pin dot-matrix, through
inkjets, lasers, and color printers.
Second, it will often output faster, or with a
higher quality, than the drivers built-in to an
Third, it allows you to transform the output in
many ways (scaling, rotating, flipping, inverting)
that the application itself may not support.
Fourth, it allows you to preview your plot file
on the screen ('printgl' can output to almost
any standard video mode).
Finally, you can often efficiently overlap
actual printing a plot-file generation.
Due to a cheapskate boss, I've been using AutoCad with some special
customizations to make PCB layouts.
The advantages are:
We already have AutoCad
The photoplotter house can accept AutoCad .DWG or .DXF files no
No problem with video drivers or plotter output - AutoCad will
work with ANY plotter and ANY printer and ANY video screen you'd want
to look at over 5 minutes.
You can draw ANYTHING. Many PCB packages have limitations in
what you can draw - only 45 degree angles, only in .001" increments,
no logo's or artwork other than text on the silkscreen layer, hard to
make new parts, can't make anything but round holes in the PCB, etc.
etc. Each one is different. Autocad can make any mark within the
dots per inch capability of the plotter.
The disadvantages are:
It's not a real EDA tool. There's no link between the board
and the schematic except in the user's mind. You can forget a
You have to draw your own parts and make your
own part library.
Everybody in the PICLIST thinks you're nuts.
Does anyone else use AutoCad to layout PCB boards?
If anyone is interested I can zip up the blocks, menus, etc. and post
them on my web page. Reply here.

I also use Autocad for PCB layouts. Most of my reasons are the same as
yours. I would appreciate having the chance to look at some of your blocks,
menus, etc. Thanks in advance.

Increvable! So there is another humanoid out there doing this! I'll
zip 'em up tonight and post them on
