Printronix ProLine 5 Series Manual page 217

Overview
There are a few general parameters to determine before using the VIEW/EJECT
print options:
It must be determined if the printer has a quick access cover where
paper is ejected from the top, or a regular cover where paper is ejected
from the rear.
The tear position needs to be set. The default of 5.12 inches is
adequate for the quick access cover. For the standard cover, 9.92
inches should be selected. These measurements are general
guidelines and can be adjusted as necessary.
The proper form height must be set. This will allow the printer to know
where the end of a page is.
The top of form setting needs to be entered.
