Vertical Forms Control (VFC)
Vertical forms control (VFC) is a feature which allows increased throughput by
enabling the printer to skip to predetermined print locations. Key page
locations, such as top of form, half form, double space, and triple space, are
referred to as channels (0 through 16) and are stored in a VFC “table.”
enabling the printer to skip to predetermined print locations. Key page
locations, such as top of form, half form, double space, and triple space, are
referred to as channels (0 through 16) and are stored in a VFC “table.”
The printer has both a standard (computed) VFC and a programmable VFC.
*All escape sequences except ESC&l0V refer to the logical page rather than
the physical page. This escape sequence causes a skip to the top of the next
physical page (unless already at top of page).

physical page (unless already at top of page).
**These channels cause a move to the next double/triple space line, and
therefore may not actually perform a double/triple space.

Note
In most situations, the printer's standard (computed) VFC page length
setting, as determined from the front panel, meets the application
requirements. Refer to the
