Use the Variable Form Length command to define the size of printable area on the label,
clarify the label length, and eliminate character clipping.
This command enables variable form length and sets the job (page) size to the last selected
value (Letter, Executive, A4, Legal, COM-10, Monarch C5, or DL).
Variable Form Length consists of a command group used to define labels longer or shorter
than 11-inches. The command group includes

Setting Variable Form Length

Disabling Variable Form Length
In all cases, the top of the logical page corresponds to the top of the printable area.
If “Ignore Margins” is set using the control panel menu buttons, or if a host command is
received to set the top margin to zero (0), the vertical cursor position of 0 is printable as the
first printable scan line on the page. (Vertical cursor positioning in PCL is relative to the
top margin). The exact location of this scan line varies with the setting of the Print Position
command in the Adjustment Menu (+ 3 mm).
See “Left Margin,” “Right Margin,” and “Top Margin” in Section 3 for information on
margin settings for standard label sizes.
Use the following software command group to define the printable area of labels larger or
smaller than 11 in. The allowable range of values is 0.5 in. to 99 in.
Setting Variable Form Length
This command is used to define labels longer or shorter than 11-inches. The allowable
