During the use of the Amiga 3000 we have seen some problems regarding the parallell interface. The problem manifests itself by lost characters and hung printers. An example: When printing a document containing only a bitmap from Professional Page (1.31) to a QMS-ps 410 it work ok if the print is done from within PPage. If one sends the file to disk and then does an ordinary copy of the file to PAR: the printer just hangs after the prologue (or one to two seconds into the transfer). These problems cannot be duplicated on A2000, A500 or A1000 to our knowledge. We have had some similar problems with an A2500 but that is not for sure. The fact that the problem only appears on faster processors hints (to me at least :-) that the parallel.device has some mild processor dependent timings. The problem is rather annoying since the entire system hangs for raw output to a port. The principle of save-before-print has to be adopted always... I would be grateful for any kind of reply! /svante -- Svante Gellerstam svante@kberg.se, d87sg@efd.lth.se

This article didn't seem to make it out of kberg, so I repost. === During the use of the Amiga 3000 we have seen some problems regarding the parallell interface.
