DATA
This command establishes the print characteristics for the logical page. The
Logical Page Descriptor command is only valid in the home state. See “XOH Set
Media Size (SMS)” on page 51 for physical medium size information.
The format of the data field (DATA) for this command is:
Before the printer can present a page of data it must know the following:
•
The units in which distances have been measured
•
The boundaries of the logical page
•
Initialization values for control parameters (margins, line spacing, and so on)
The controls established in a Logical Page Descriptor command remain in effect
until the next Logical Page Descriptor is received unless superseded by explicit
controls in other commands (see “Write Text (WT)” on page 62). In any case,
the latest LPD control values are restored with each Begin Page or Begin
Overlay command.
The LPD command is valid with 24, 28, 34, 36, 38, 40, 41 or 43 bytes. The 64XX
accept the LPD command using any of these valid lengths.
