I get into trouble if I choose A4 borderless instead of A4 in the Photoshop Print settings.
There, Tray 2 is dimmed out
To be honest, I don't see borderless in your settings, but my doing that on my printer causes a default to the larger Tray 1.
That's all I have tonight. If I think of anything else, I'll post it. Here's thread on this issue as well.
Wrong paper size sent to the printer
