double sided printing mystery: over the weekend everything in X3 began printing double sided... any ideas?

SOLVED

Hi All,

On Monday we noticed that all of our multi page print jobs began printing double sided. (This was not happening the previous week).

This is system wide and not isolated to one printer, it is great for Picking Tickets but not great for printing checks :-)

During the troubleshooting process we have verified all print settings on printers.

Rebooted the "Windows 2012 R2 Print Server" (all print jobs other than X3 are behaving as expected)

This seems to have all of our support channels stumped, so I am reaching out to see if anyone in the community has had a similar issue.

Thanks in Advance - Shane
