We've installed two new Ineo 421 Printer / Scanner / fax machines on our Windows domain. We use access as a front end on an internal CRM-type system. We use snapshot viewer for reporting. When either of the new Indo421's are set as default printer, the snapshot viewer stuff won't run, no error messages, nothing. As soon as you change the default printer to any other printer (One is an Ineo 350; PDF printers etc all work fine) anything that uses snapshot viewer to make a report before printing doesn't run.
All updates etc are applied to access and the snapshot viewer installs are from the latest install files.
