Adding Paper Trays
The PDF printer is built without any paper trays or paper bins.
However, sometimes the printing program require that you select a
specific tray of paper before you can print.
I will show you how you can modify the printer definition file to make
the printer think it has a collection of virtual trays.
Modify the PPD file
The printer's definition is stored in something called a PPD file
installed with the driver. Here is how you modify it:
Find the PPD file that matches your printer in this folder:
At the end, you can add this line and save it:
*InputSlot Tray1/Tray 1: ""
Try printing again and see if you have a "Tray 1"?
