Hi Andrew,
We also use VPS, VPS/TCPIP, DRS, DRS/TCPIP. We run about 500-600 active printers and we also use VPS/TCPIP and DRS/TCPIP to, among other things, receive data from other platforms, write it to JES2 for printing, or write it to z/OS datasets for for further processing on z. Having installed/configured the LRS products in my shop since 1998, I agree with Eileen, especially as regards LRS support. They have always been wonderful, whenever we needed to call. We have already completed our SNA to IP conversion. We do not use Enterprise Extender for customer print applications at all. We use VPS/TCPIP. We completed our conversion in about 6 months. Most of our customers moved from old Telex SNA only printers, so that time included they time they needed to replace their printers too. If our customers had already had IP printers, The cut over mo ved faster . One of the things we found during our conversion was that many of the reports going to the SNA printers were written using SCS support on the old printers. We addressed that by adding PCL (or Postscript can be used) page presentation control in VPS. That happens on the fly, and is done using VPS. That allowed the SCS reports to print properly on the IP printers. Applications was happy not to have to re-work the out put for the printer change. We did find some things we needed to watch for. I'll be happy to share those if you would like.

Hi all, I have a situation where we'd like to replace SNA connections to remote printers with "pure" TCP/IP. The print devices are ordinary LAN printers like HP LaserJet, etc. Currently these are connected by DLSw-attached Microsoft HIS servers. Replacing DLSw with Enterprise Extender is not an option, for complicated business reasons :( One possibility is to use TN3270 printing, using the IBM TN3270 server on the host. However: - the only TN3270 Print emulators I can find are "workstation" style products, like Attachmate Extra or IBM PCOMM. - some print jobs may require formatting via PDT files. So my questions are: - are there any TN print servers/emulators which are scalable to "server" workloads, ie, printing thousands of pages a day and many concurrent print jobs from the host? Not just puny workstaion style printing. - are any TN3270 print emulators able to format complex jobs using PDT files, or similar? This site uses VPS printing from LRS. VPS/TCPIP is an option, but that is a large project which may take years to deploy (this is for a large bank). I need a tactical solution for the next 6-24 months, at least. Very grateful for any comments, suggestions, ideas or info!
