Limited success Jim.
I do NOT have the TMG PDF printer installed (deleted from control panel devices and nothing showing in device drivers).
I am running TMG as an administrator.
Under printer set-up, I have selected my regular printer. If I try to send a Family Group report directly to the printer, I get the OLE error/class registration message. After ignoring it, I'm returned to TMG. Nothing printed.
If I try to send the Family Group report to a screen preview, I get the OLE error (which I ignore) followed by a "Unknown Member PDF" error (which I ignore 3 times in succession). The preview then shows on my screen as expected. Once I press the printer button in the upper left corner, I get the "Unknown Member PDF" error again...after which I get the normal Windows print dialog and all proceeds as expected.
