Epson ET-7750 print register issues from rear feeder

[The Hat]

I've printed via the following; Epson paper layout, Preview, Air print,

Uninstall the Air print driver and use the Epson print drivers instead..
That might help...

This has been resolved!. I reset the printer to its default settings, uninstalled all the Epson drivers, then installed only the Epson driver. All is now good. Similar to The Hat's suggestion.

I can now print out with confidence colour test targets for profiling.
