Vertical Forms
Control
Vertical Forms Control (VFC) allows the user to skip to a predefined
line on a piige of print with only one command instead of using a
number of line feeds. This capability can greatly increase the speed of a
print job.
Your printer is equipped with a standard and a programmable VFC.
When the printer is powered-up or reset, it defaults to the standard
VFC.
The standard VFC contained in the HP2566C/HP2567C printer is a
computed VFC, meaning that the VFC automatically adjusts its skip
lengths when the form length is changed. The standard VFC channel
definitions are listed in the following table. The terms “Top of Form”
and “Bottom of Form” refer to the top and bottom of text on the page.
More information about the programmable VFC is found in the HP256X
Printer Family Technical Reference Manual, 02564-90905.
