I was thinking yesterday that it would be relatively simple for one to convert Postscript files into Epson, etc. sequences for draft style output. Obviously it would not be of a quality to be used as final output, but a dot matrix is significantly cheaper than a laser overall - base price, supplies, duty cycles, etc. Surely someone out there has done something like this. Is there some standard software available? Thanks! -- Larry W.

Just write a PostScript interpreter, develop nominal 1-point font outlines for 35 fonts, write a translator to convert whatever nominal bit map PostScript thinks in, and write some utterly trivial code to convert say, 1000 dpi bit map to 180 dpi bit map (note the common factors in 1000 and 180), and you've got it done! Sorry to be so sarcastic, but I don't think most people realize yet how powerful PostScript is, and how non-trivial such a program is. Clayton E. Cramer

Anyone who thinks converting PostScript to Epson is simple has not looked very hard at the problem. It is definitely NOT simple. Think about the implementation of the curves, gray scale, text in different styles at any angle, etc. There is no simple way (such as a filter) of making the conversion. I am finishing up a bitmap package for the Postscript Interpreter posted a while back. When it's finished the bitmap output should be printable on an Epson printer (or anything else for that matter). Writing the bitmap package has not been simple. Writing the Interpreter was certainly worse. Yes, when I'm done I will be posting the source for the bitmap package. -Chris Cox cc4b@andrew.cmu.edu

I am sorry that mr cramer felt it necessary to be so sarcastic; I have gotten private mail from several others who also have this need ; see, there are those of us in the world who can only affort dot matrix printers; when your hardware makes the assumption that postscript is the standard output - and you all know what kind I am talking about I will bet - then finding these filters become more than a convienience. Note that we have seen dozens of postscript - something or something -> postscript filters posted to the net; since there are many more dot matrix printers out there than laser I figured that one of the brilliant ones would have done this; I mena, the postscript interpreter is already done and was posted to comp.sources.unix. The appropriate driver is needed, but there are fonts galore - and some of us have dot matrix printers which allow fonts to be downloaded. -- Larry W.

Virden 75046,606 (CIS) I would like it also -- my sarcasm was a little strong, but having spent a bit of time chasing down the problem, (and studying the very significant problem of getting useable performance doing full page graphics on dot matrix printers), the request struck me as equivalent to, "Does anyone have a public domain program that accurate simulates and predicts the stock market?" Sorry if I offended anyone -- that really wasn't my intent. Clayton E. Cramer

I am also looking for a Postscript to `matrix filter. If anyone finds one please e-mail me the info... thanks in advance,
