Ten years ago this summer, HP's 3000 lab engineers were told that 3000 users wanted networked printing. By 2005 it was ready for beta testing. This was one of the last enhancements demanded as Number 1 by a wide swath of the 3000 community, and then delivered by HP. The venerable Systems Improvement Ballot of 2004 ranked networked printing No. 1 among users' needs.
MPEMXU1A is the patch that enables networked printing, pushed into General Release in Fall, 2005. In releasing this patch's functionality, HP gave the community a rather generic, OS-level substitute for much better third party software from RAC Consulting (ESPUL). It might have been the last time that an independent software tool got nudged by HP development.
The HP 3000 has the ability to send jobs to non-HP printers over a standard network as a result of the enhancement. The RAC third party package ties printers to 3000 with fewer blind spots than the MPEMXU1A patch. HP's offering won't let Windows-hosted printers participate in the 3000 network printing enhancement. There's a Windows-only, server-based net printing driver by now, of course, downloadable from the Web. The HP Universal Print Driver Series for Windows embraces Windows Server 2012, 2008, and 2003.
Networked printing for MPE/iX had the last classic lifespan that we can recall for a 3000 enhancement. The engineering was ready to test less than a year after the request. This software moved out of beta test by November, a relatively brief five-month jaunt to general release. If you're homesteading on 3000s, and you don't need PCL sequences at the beginning and end of a spool file, you should use it. Commemorate the era when the system's creator was at least building best-effort improvements.
Deep inside the Web is a white paper that former HP staffer Jeff Vance wrote, a guide he called "Communicator-like" after the classic HP technical documents. HP's taken down its Jazz repository of tech papers where NWPrinting.html once was available. But our open source software expert Brian Edminster tracked down that gem at the Client Systems website -- the company which was one of two to license HP's tech papers. You could check in with your independent support provider, to see if they've got the paper.
Networked printing was never as comprehensive as the indie solutions for the 3000, but at least it was delivered on the OS level via patches. The vendor still warned that adding new printers was going to be an uneven process.
HP will support this enhancement on a "best-effort" basis, meaning we will attempt to duplicate and resolve specific spooler problems -- but we cannot guarantee that all ASCII based printers are supported by this enhancement.
Of course, HP's support is long gone. But while best-effort might sound like a show-stopper so many years later, you'd be surprised how many printers of that 6.5 era are still attached at homesteading 3000 sites.
Where do you get the patch? That's where HP's still doing its work. These MPE/iX patches were given special dispensation from the pay-for-patches edict of 2010. They're still free by calling HP. That non-Windows printer and MPE might seem like old technology. But HP's still using telephones to enable the delivery of patches, so there's that Throwback -- and one you can find on days which are not Thursdays, too.
