altering postscript code on the fly to get pure black and white
in [Device Drivers]

From: sean_n on 10 May 2008 08:22 altering postscript code on the fly to get pure black and white Hello, is it possible to alter postscript code (not manually, but on the fly via a script or utility or whatever) before it is sent to a printer? I'm guessing not, but just thought i'd ask just in case. I want to convert the postscript code so that it prints pure black and white, no greyscale. Our users are complaining that the greyscale is coming out too dim. I was thinking about inserting the following line at the beginning of the postscript stream, {.999 lt {0}{1}ifelse} settransfer Alternatively, I have considered setting up the printer queue so that it prints to a postscript file instead of sending it to the printer (This is done by setting the local port to a file path instead of an IP address). Then altering the file via some script, then sending it to the printer. Although, this really doesn't work well in a multiuser environment as the file can get overwritten before it is altered. Please send any suggestions that might help, thankyou. p.s. Some background on me, in case it helps. I don't know anything about developing printer drivers, but i know C++ and am willing to try driver development if necessary.

If a document's greyscale color is too dim, then isn't the proper response to tell the user to use a darker color? -- Tim Roberts, timr(a)probo.com Providenza & Boekelheide, Inc.
