Print Preview not retaining Crystal Report Page settings nor OS default Printer page setting keeps defaulting to "letter"

Wonder if anyone has picked up this issue or whether or not this is considered a "non" issue

Products in question Sage 300 ERP 2012 PU3, Win Server 2008 R2, Workstations OS's vary from Win 7 (64x) to Win XP, Custom written reports Crystal XI, custom page sizes defined.

We noticed at a client, when they where printing invoices (confirmed since that this occurs on any report type) that the print preview will default to the printer as specified within the report but the client has to manually select the paper type each time they want to print (defaults to letter even though custom page size specified in report "invoice") even though the printer and paper type are pre set within the report and the same settings are defaulted within the OS printer settings.

I initially thought this was only on one workstation but have since confirmed that all the workstations in the environment are affected. It doesn't sound like a major issue until you realise that they are printing large volumes of invoices. Has anyone else experienced this and any suggestions as how to get the page setting to save on the custom selection?
