I've got another site that has Kyocera printers they expect to be able to use with adagio. It works with everything else, and it worked with adagio in the past.

Hard to avoid explaining that it's a unresolved bug, which is too bad as Softrak is generally good at responding to bug reports and the client is left with the wrong impression.

If you get the invalid printer message, change the default printer for reports to a non Sharp/Kyocera driver and then print from within the report preview to any desired driver. Or try to convince them that paperless reporting is better (hold-outs here are usually die-hards at this point).
