1. Printing Graphics?
A lot of good stuff concerned with graphics has been presented
here; there are quite a number of good graphics programmers
here (I wish I were one of them). I don't recall, however,
seeing any discussion of _printing_ graphics. Does anyone
have any routines to take a graphic captured with a
save_screen and print it out on the printer?
The optimal routine will be able to support the following:
300dpi PostScript laser printers (Can assume PS Lev 2, but PS Lev 1 preferre
d)
Color-to-grey or color-to-halftone conversion
screen black to paper white
screen white to paper black
300dpi non-PostScript laser printers (can assume HP LJ-III)
Color-to-grey or color-to-halftone conversion
screen black to paper white
screen white to paper black
300dpi color inkjets (in color) (can assume HP DJ-550C)
screen black to paper white
screen white to paper black
216dpi dot matrix printers (can assume Epson ESC-P-2 language).
screen black to paper white
screen white to paper black
From my point of view at the moment, the most urgent
requirements are for the color inkjet and non-Postscript laser
support.
Optimal structure would be a set of includable routines that
don't require foreknowledge of the target printer (i.e.,
user-selectable at run-time, even if in a bound program), but
a routine that will save a screen capture to disk, and then
separate programs that will read that saved capture and then
print it out would be acceptable.
Also, is anyone familiar with the GWBASIC/QBASIC BSAVE format?
Support for that picture format would be a nice thing to have.
