DECSHTS

(continued)

Error Handling

If the printer receives more than 16 tab stops, it sets the first 16 and
ignores the rest. If the same tab stop is sent more than once, the
printer sets the tab stop once. The printer ignores a sequence sent
without tab stop parameters.

When the number of new tab settings exceeds the maximum, the
printer discards the tab stops with the highest values.

DECSLPP

Set Lines per Physical Page: Defines the logical form length. The
form length is the vertical size of the printed area on a page.
Source: Application

Destination: Levels 1, 2

Format

CSI Pn t
Description

This command sets the page length to the physical distance that
corresponds to Pn units (lines at the current vertical pitch,
decipoints, centipoints, or pixels). Once form length is set, changing
the size of the units does not change the form length

If Pn equals 0, the printer sets the form length to the logical paper

size. Pn is a number of units, depending on Positioning Unit Mode
(PUM) and Select Size Unit (SSU).

The following table lists the parameter values for a small selection of
page lengths as a function of vertical pitch. These values are used
only when PUM is reset.

Where N/A is indicated, the length is riot selectable while the
indicated vertical pitch is in effect. If it is selected using another
vertical pitch and a subsequent pitch change occurs, page lengths of

a non-integral number of lines may result. Page wrap occurs after the
last whole line.

The form length limits the range of possible settings for the Set Top
and Bottom Margins (DECSTBM) command.
Side Effects

The printer resets the top margin to I and the bottom margin to the

printable area when changing page length. DECSLPP also resets the
vertical format bounds to the margins.

DECSLPP affects justification. See Justify (JFY).
