- Big Red Computers
- GPrint3200 is a simple program which allows you to print out 3200-color L
- Jgraphics on an ImageWriter printer. Because it bypasses the Print Manager N
- LToolset, it will only work with ImageWriter printers (the codes are part of
- the program).
- Print3200 requires System 5.0.4 or higher. It prefers System 6.0.1. It also 4
- requires at least 1.25 Megabytes of available RAM.
- FPrint3200 is being distributed as "Freeware". You may freely copy and L
- Jdistribute the program for non-commercial purposes. Please make sure the P
- Nfollowing files are also distributed: Print3200, Print3200.Docs, Sample.3200, L
- Jand Big.Red.Info. Print3200 is copyright 1995 by John Wrenholt. All other
- rights reserved.
- Print3200 has the following menu options:
- MOPEN - This allows you to open a 3200-color graphic. Graphics are recognized M
- Kby their filetypes and by their filenames. All filenames must end with the F
- suffix "3200" or "3201". Print3200 can open the following filetypes:
- 3200 APF
- Filename must end in "3200"9
- 3200 Raw $C1 " " " " "9
- 3200 Raw BIN " " " " ";
- 3200 APP French Filename must end in "3201"
- HPrint3200 does not allow you to open 3200 PackBytes or 3200 DreamGrafix N
- Lpictures. If you have DreamGrafix, you can use it to change the filetype of
- these graphics.
- CLOSE - Closes the graphic that is currently open.
- FDISPLAY - A very lame routine which allows you to view the 3200 color N
- Lgraphic. It shows you 15 lines of the graphic in their actual color and the O
- Mrest of the image in a grayscale palette. You can use the arrow keys to move O
- Mthe color band up and down. Press "Space", "Escape", "Return", or the mouse "
- button to exit the display mode.
- LPRINT - This allows you to print the current graphic. You will be presented 6
- with a print dialog. You have the following options:
- Image Size: This popup menu allows you to select the size of the &
- printed image. The default is small.
- Quality: This popup allows you to select either "Standard" or "Best" N
- Lquality printing. "Best" quality turns on unidirectional and bold printing. P
- NThis gives a darker image but slows down the printing process. The default is
- standard.
- Chroma: This popup menu allows you to select rather you want to print P
- Nthe graphic in black/white (boring) or color. It does not check to see if you 6
- have a color ribbon installed. The default is color.
- Form Feed: This popup menu allows you to select if you want the program M
- Kto issue a form feed to the printer after the graphic has been printed. If I
- Gyou select manual, then no form feed command is issued. The default is
- manual.
- Orientation: These icons buttons allow you to select rather the graphic B
- is printed normally or in landscape mode. The default is normal.
- IIf you select the "Ok" button, printing will commence. Once printing has 7
- started, you can cancel it by pressing "Open-Apple-."
- QUIT - Quits the Print3200 program.
- The History of Print3200
- MSeveral years ago, someone bet me that it was impossible to print 3200-color O
- Mgraphics. It was a challenge that I couldn't ignore. Using code from several H
- Fdifferent programs that I was working on, I quickly patched a program E
- Ctogether and proved them wrong. Since the program had no practical O
- Mapplication, I quickly forgot about it. Last month, I was busy cleaning off O
- Mmy IIGS's hard drive when I rediscovered the code. I thought it might be fun M
- Kto clean up the code and release the program as freeware. Although it only L
- Jtook one afternoon to get the original code working, I've spent two weeks
- adding bells and whistles.
- LPrint3200 works by converting the IIGS's RGB (red-green-blue) palettes into O
- MCMY (cyan-magenta-yellow) palettes. It then selects a dithered pattern which H
- Fbest represents the CMY palettes. Your ImageWriter is only capable of M
- Kprinting 5 "pure" colors: yellow, red, blue, black and white (the color of J
- Hyour paper). By overprinting it can also print orange (yellow and red), O
- Mgreen, and purple. All other colors must be generated by mixing and matching L
- Jthese colors. For example, light blue is created by printing a pattern of K
- Iblue and white dots. The ImageWriter does best when it is working with a O
- Mlighter palette. If you get too many browns, greens, purples and blacks, all M
- Kyou'll get is a muddy mess. After all, there's not much difference between H
- Fdark green (a green and black pattern) and brown (an orange and black
- pattern).
