Line Spacing
Vertical line spacing of 6 or 8 LPI (lines per inch) can be selected either from
the control panel or remotely using the ESC&l[6 or 8]D sequence. When the
printer is reset, the vertical line spacing is as set from the control panel. If a
parameter other than 6 or 8 is entered, the command is ignored and no line
spacing change is made.

printer is reset, the vertical line spacing is as set from the control panel. If a
parameter other than 6 or 8 is entered, the command is ignored and no line
spacing change is made.
NOTE: Changing the line spacing causes the standard VFC table to be
recalculated.
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.”

The printer has both a standard (computed) VFC and a programmable VFC.
The following paragraphs explain each in more detail.

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
requirements. Refer to the
User’s Manual for information on setting
the page length from the front panel.
Standard (Computed) VFC
The printer VFC uses the logical page and form length (text length) to
calculate the distance to be skipped for each VFC channel. This information is
then loaded into the printer's VFC “table.” The “table” is 16 channels wide and
n lines long, where n is the logical page length in number of lines. A VFC
channel contains a 1 in this table on every line it can access. If the VFC
channel cannot access the line, a 0 is placed on that line for that channel. For
example, to specify a skip to the next half form, a program would specify VFC
channel 6. Notice in the sample on

finished printing line 2 and channel 6 is selected, the paper will be advanced
to line 9.

To use the standard VFC, perform the ESC&l[0 through 16]V sequence using
the appropriate parameter number listed in
