ImageWriter emulator #42

Open knghtbrd opened 8 years ago

knghtbrd commented 8 years ago

I noticed "disk 7" included a PostScript file providing an ImageWriter emulator. I assume this is B&W only because at the time PostScript printers like the LaserWriter didn't have color. Do we know any PostScript/GhostScript people who could get that working? Is there a better alternative? Even more awesome if someone knows enough PostScript to add color ribbon support. :D

Something for later.

I made reference to this issue on Facebook and got this reply from Mario Patiño:

Hugh Hood posted some time ago a modified IWEM that does this on csa2 http://macgui.com/usenet/?group=1&id=278578#msg

That looks extremely promising!

I had added color support to IWEM many years ago, but Postscript has limitations when it comes to "overprinting" colors like most Apple II applications do. You can't blend yellow and cyan to get green since PS doesn't support transparency.

Another option is the Imagewriter LQ emulator that is in GSport. Its written as a C++ library and can be converted into a daemon that monitors a real serial port on a Pi OR can read standard output from a printer queue. It renders output to Postscript (basically a large image wrapped in PS), BMP, and PNG, all of which can be piped into CUPS.

Can we perhaps address that with modern GhostScript?
