You might consider setting up a custom paper profile on the printer itself. This is easy to do and would allow you to select it quickly from the printer menu. To paraphrase the manual:
PAPER SETTINGS: When you select STANDARD, the printer determines the paper thickness automatically. You can also select No. X (X can be any number between 1 to 10) to register or recall the following settings you have made (from a custom paper profile):
- Platen gap
- Thickness pattern
- Thickness number
- Cut method
- Paper feed adjustment
- Drying time
- Paper suction
- MicroWeave adjustment
Look at the PAPER SETTINGS instructions in the Epson 7800-9800 Manual. The printer will allow you to calibrate your media for optimal printing.
