Firstly, on the much discussed "ps to eps" front, would Glenn Ried's program "distill" perhaps be a good place to start work on a utility that could produce eps from general ps. It could read the incoming PostScript, distill it, then write an eps conformant file as its output. Secondly, a question. Does anybody have any details of the FAX and CCITT Group 3 & 4 extensions in PostScript level II? A recent posting from somebody (thing?) called "ouij@xurilka.UUCP (exhausted jazz surfer)" of the "Church Of Surfing Anarchists" said; >> CCITT stuff will come in handy as we see the proliferation of >> PostScript fax machines. Does this mean that machines are available that take PostScript in one end and spit Group 4 Fax images out of a PTT approved modem at the other? Thirdly, a query. Has anyone had any experience using PostScript printers (either Adobe or clone) with parallel (centronics) input, if so, is it possible to "get at" the standard output stream? Where do those nice error messages go? Regards Brian Cockburn.

Under centronics mode, the returned error message go out the 9 pin serial port. Just why they should go out that particular RS-422 port, is a mystery. Normally people use the 25 pin port. You have to have your computer print to a paralell port, and read from a RS-422 port essentially at the same time. Cheers Woody

In the serverdict there is generaly a procedure known as switchopen or something similar. In interactive mode i.e. over the 25pin serial link, type in executie<CR>. This will get you to the interactive mode. Then, do the following: turn on your ascii capture option and do /serverdict load {== ==} forall You will be looking for an executable array of procedures. There is one for each switch setting. You will find that entry 4 is the centronics setup code. In it, there is an explicit open of the 9 pin port. If you copy this code, and then change the ref from 9 pin to the 25 pin port, and execute it , it might work. Just a thought. Cheers Woody
