The plot thickens.
Over an hour with epson support, here are the key settings that made it work:
Orientation: Portrait
2-sided Printing: On
Binding edge: 2-sided short edge
Two-Sided Printing: Short-Edge binding
Duplex Tumble: None
*notes:
1. borderless printing is not available when printing...
On the phone with epson I got it to print on two sides, however binding on the long edge.
Trying to change that to the short edge resulted in its printing two pages separately again.
Now I'm on hold as the indian lady speaks to higher level tech support.
I've managed to make amazing pictures with the ET-8550. I've tried making my own ICC profiles, I've got the paper selected that I want, it's all perfect...
Now I'm trying to print a PDF manual I downloaded online on two pages on plain U.S. letter paper (using the mac).
My brother printer makes...
But why don't the manufacturers build this in to the printers?
It seems only logical. Calibrate the scanner from the factory, iirc those don't have the tendency to "walk" in calibration, and then make it a trivial matter to simply load a new paper and create an ICC profile. Save it into the...
Like actually....
I understand scanners need calibrating.... but not nearly as much as printers....
Wouldn't it make sense to simply load whatever ink/paper, print out a specific color test sheet the firmware can recognize, scan it, then iterate on that process to calibrate the printer...
At ~11:45 of this mini documentary on Faber Castell they discuss and demonstrate how they test their pigments for longevity, but it's an American documentary, so not very in depth or detailed.
Epson has an ICC profile manager utility that iirc lets you change the default ICC profile inside the printer.
I couldn't find a download to even test if it would work on the ET-8550. Epson says it won't work, but they say the same thing about their Print Layout software, and that works...
