Logical Page Descriptor - Ricoh MP 6002 User Manual

Logical Page Descriptor

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...)
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Page Descriptor is received unless superseded by explicit controls in other commands (See p.121
"Write Text"). 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 printer accepts the LPD
command using any of these valid lengths.
