A Utility to print Windows 3.0 icon files on HP LaserJet printers
vers 1.0 by Monte Ferguson
You've probably downloaded a major quantity of icon files (*.ICO) for
Windows 3.0, but how can you keep track of what they look like? Here yah
go - dump the whole mess of'em out to your LaserJet.
Usage is simple enough:
DUMPICON [path] [/V [/43] [/50]]
The [path] tells the program where to look for *.ICO files. It's
optional, if you don't specify a path it'll look in the default drive and
/V engages "Visual Mode" - it previews the icon on the screen in all 16
glorious colors. Along with the /V switch you may want to include the /43
(43 line for EGA) or /50 (50 line for VGA) options - icons are 40 rows
tall, using one of these extended text modes will fit the entire icon on
The output goes to LPT1:
NOTE: This program was tested using an HP LaserJet III with 4Meg of RAM
and seems to work OK for me. Which is ALL the guarantee you get. If it
works for you too, I'm tickled... if not, well, it's not like you PAID for
this or anything, so quitcherwhining! 🙂
It may work on other HP LaserJets (or compatibles...?) if they have
enough RAM to print full-page 300dpi graphics. Maybe. I dunno.
EXCUSES: I'm not a Windows programmer, I figured out the *.ICO file
format by "brute force" - I just stared at it until it made sense. So I'm
probably reading it wrong (it looks like some icons might be a little
taller than they should be...?). If anyone has info on the actual file
layout I'd be glad to make the necessary changes in the next version of
RE: Dithering... this is the first time I've ever tried something like
printing color images on a B&W printer, so I made it up as I went along.
The dithering routines are completely seat-of-the-pants hacking... it
seemed to make sense at the time, and *I* like the results.
