Epson Surecolor P9000 and single cut

Seems whenever we print (using Photoshop primarily) even though we are set to "single cut" borderless printing mode, and are printing several jobs right after one another, the printer always defaults to double-cut (wasting a strip of paper between each print). Tried it on Mac and PC, connected USB and network, and with "Print directly to printer" on and with "Spool print jobs" on (on Windows--Mac doesn't have those options).

If I print multiple copies (via the copies field in the driver's print settings) it DOES perform single cuts, with no waste strip. But simply clicking print successively, always gets the wasted strip as it goes into 2-cut mode.

So--I'd like to ask any P9000 (or P6000, P7000 or P8000) owners out there--have any of you had success printing with no waste between prints via single-cut mode on these printers?
