Hi, all -- I've got a problem: I've got a postscript printer (IBM "E") hooked up to a datakit network. It's being used through the UNIX lp utility to print relatively small (<15K) postscript files. However, after completing a job (the page has been ejected), the form feed light on the printer remains on and steady for about five additional seconds. Any new jobs sent during this time are lost (the FF light blinks, indicating that processing is occurring, but then it goes out and the job dies). I need to figure out how to get the printer to acknowledge an "end of job" as soon as possible after the job is complete. I've checked the red, green, & blue books; maybe I'm looking in the wrong places, but I can't find any "reset printer" type commands. Could this problem possibly be printer dependent? Any help would be appreciated . . . Andy

Lots of people will suggest sending control-D to the printer at the end of your job, since it's connected over a serial line, and I'll suggest it, too. Many of those same people will also point out that control-D is really part of the serial-line protocol and not part of the PostScript language, which is why it's not in the PS code to begin with, and why the spooler should add it at the end of each job. Just out of curiosity, you might also try adding the "stop" operator to the end of your file. It should have a similar effect, I think, and would be completely portable, unlike control-D. -- Glenn Reid RightBrain Software glenn@heaven.woodside.ca.us NeXT/PostScript developers ..{adobe,next}!heaven!glenn 415-851-1785 (fax 851-1470)
