QTR-Quadtone RIP

This is probably a question for Roy?

I’m printing with QTR 2.7.5 on an iMac running 10.10.4 and printing with Print Tool on an Epson 3880.
I also print with QTR with an Epson 9800 and it is working fine.

I been printing with this combination for quite a while with no problems.

When I tried to print through Print Tool today, under Printer, I selected Quad3880.
Under Paper, when I select Quad 3880, under the selection it does not say QuadToneRIP 2.7.5 Epson 3880, it is blank?
When I press Print, then Layout, QuadToneRIP is not a choice to select?

So I went to System Preferences, Printers & Scanners, and noticed that the Quad3880 Location: showed Direct USB Printer and Kind: is left blank? Unlike the Quad 9800 which shows Location: USB Printer and Kind: QuadToneRIP 2.7.5 Epson 9800.

I have deleted the Quad3880 printer and reinstalled through the Install3880.command and it installs as a Direct USB Printer?
I tried downloading QTR 2.7.5 and reinstalling the software and this had no affect on the problem.

I am stumped at this point?
I have never seen the Location as Direct USB Printer before today?
Nothing has changed hardware or software wise prior to this issue.

Appreciate any help, thanks, Doug
