I just purchased an Epson SC-P900. It will replace a wonderful 3880 that has not given me a bit of trouble in the 10 years I've owned it, clearly one of Epson's best machines. I succumbed to the instant ink switching, matte to photo and back, and the recent announcement by Roy Harrington that the QTR RIP now works on the P900 with matte paper.
My question is how does the printer know which ink to use?
I assume it decides based on which paper is chosen on the control panel.
The reason I am asking is that when I use the QTR RIP, latest version, the printer dialog gives only one option, photo black; there is no option for matte black. If the choice on the printer overrides this, fine, if not, I've got a problem.
I read the entire manual for the printer, the tutorial for QTR (which I've used for many years) and googled "how does the P900 knows which ink to use?" and did not find a solution.
Any thoughts from P900 users would be most welcome.
