Our ERPs SAP and Oracle print over a local print server. We want to use Universal print to leverage printing over the internet without any type of VPN for a remote site. We tested printing from SAP using SAP Print Service. It only works going through a Local Printer with "Microsoft OpenXPS Class Driver" first, which prints to the UP printer. Here the diagram. Working solution.
However, we also use Oracle ERP and the print job is sent by a linux server. I tested it, but I was not successful. Same as above but printing directly to CanonForSap printer. I believe this is a key requirement for us to fully leverage this super cool new feature. Please consider this. I also opened a case REG:120060224004056.
