This is because there different handshaking schemes that can be implemented on the Centronics interface. I don't have a copy of the IEEE specification at the moment so I can't be more specific. One of the big problems about the Centronics interface is that there are 2 specifications, which use the BUSY/READY signals in a slightly different way. Another big problem is that the IEEE specification is an evergreen document, i.e. it is constantly changing.

Incredible, I have changed the printer cable, and now the Epson Stylus prints!

Re: Strange behavior of lpr+lpd
I can not comment on the thread as developed so far, but let me add that since I have moved to debian1.1, lpr does not reliably print to a printer that worked for 0.93. The printer is an Apple 16/600 accessed directly via tcp/ip. If i send a printjob to a different IP address that is a Gatorbox that forwards jobs to the same 16/600, all is fine. I originally thought the problem was for printjobs sent to the printer via stdin (ie the print button xpdf, etc), but I had a couple of failures for regular files. The final straw was when my linux box apparently was flooding the printer with some sort of communication, thus choking it for hours at a time. I am afraid that since this was at work, I have not had time to pursue a rigorous debug of the situation. I have started to just use Windows for now since Word documents emailed as attachments seem to be our stock in trade. I had xbin in my old Linux but have not tracked it down again to build it for the new kernel. Just rumbling to see if this rings a bell. i can record detailed release numbers if necessary (I'm not in Linux :-( ) hunter -- TO UNSUBSCRIBE FROM THIS MAILING LIST: e-mail the word unsubscribe to [EMAIL PROTECTED] .

Strange behavior of lpr+lpd
Hello to all users, I have a problem with debian1.1.4 lpd+lpr. I had previously debian0.93 and a 9pin dot matrix printer. I write my printcap, used ghostscript in a filter and used lpr to print files. Then I sold my 9pin printer and I bought an epson stylus color pro. I also upgraded 0.93 to 1.1.4. I wrote a new filter and nothing come out of the printer. So I invoked the filter manually with the output redirected to /dev/lp1 and all worked fine. I also tried apsfilter and magicfilter but they did not function. So, I think the problem is in lpr+lpd. Please help me!!
