In QTRGui you set all the options (paper size, curves) the way you want and then you set QTRGui to “monitor” a folder, the one that Qimage deposits its processed files into. The workflow is you set Qimage to print to a file. Some people prefer its on-the-fly resizing and sharpening algorithms. It is possible to integrate Qimage and QTR, but the workflow is quite different. If you’re printing using Qimage and a Piezo supplied ICC, then I guess you’re attempting to simulate the Piezo look, except that Qimage won’t know anything about the Piezo Pro inks and will be trying to do that with OEM inks, and what you actually get will be a roll of the dice. Qimage only prints to installed (physical) printers.

It’s a separate program with a GUI front end, QTRGui, that interacts directly with the printer, bypassing the Epson printer driver.
QIMAGE ULTIMATE MANUAL INSTALL
On Windows QTR does not install as a printer.
QIMAGE ULTIMATE MANUAL FOR MAC
Print Tool is one such application, and I think that Qimage One for Mac now also does that. In practice, if you don’t want to print using ICCs, and many people don’t, then there are only a few programs that will enable you to do that and not have the OS do hidden color management. Given this, in theory you can print to QTR from any application. So you would see two 9890 printers - the physical one and a virtual QTR one. As a Windows QTR user and sometime Qimage user (and a very occasional Mac user) perhaps I can elaborate a little on Walker’s reply.
