- Why the opacity? For overhead transparencies, or for contact

- dandy for overheads, but not really quite up to it for the contact
- printing work.

- You should be able to get a LaserJet IIP in this range, maybe even the
- IIP Plus. (IIP if anyone still has them...)

- Overheads are quite nice; one of our folk did some presentations with
- color slides and they were bright and crisp. The black transparencies
- were fine, again for overheads.

- But for 24 bit color at 300dpi, if you really mean each dot can be one
- of 2^24 different colors, you better plan on a LOT more than $1000 at
- this point. The inkjet either puts a dot of a primary color at a location
- or it doesn't--there's no partial dot. So you only get a few possible
- colors at each dot. Shading must be done by dithering.

- Amiga memory shouldn't matter, unless you are assembling whole pages there.
- Then a single plane 8x10.5" of 300dpi is about 945,000 bytes. In a
- laser printer, you have to have the info for a whole page in the printer
- before you start printing the page, so yes, 1.5 megs is about the
- minimum for graphics. BTW, the LJIIP+ is faster at accepting data than
- the LJIIP, and if you are printing multiple different pages of full
- graphics, the transfer time can get to be a pain--and if the program/
- driver you are using is slow, that makes it just that much worse. This
- can be a big advantage for PostScript, or for a program that downloads
- softfonts to the printer for text applications instead of printing pages
- as graphics.
