Page Segment Function Set Commands
The page segment function set contains the commands the printer uses to store, delete, and present
information in the page segment memory of the printer. These commands are independent of any specific
data types defining the page segment. The following commands are the page segment function set:
Command Code Description
BPS D65F Begin Page Segment
DPS D66F Deactivate Page Segment
IPS D67F Include Page Segment
The following pages describe the page segment function set commands.
Begin Page Segment (BPS)
Length D65F Flag Correlation ID (Optional) DATA
The Begin Page Segment command causes the printer to enter the page segment state. This command is
only valid in the home state. Receipt of an End Page command while in the page segment state causes
the printer to return to the home state.
The Page Segment command defines a segment of page data to save within the printer for later printing.
This printer later includes this segment when it receives the Include Page Segment command.
The DATA field is two bytes in length and can be any value between X'01' and X'7F'. This value is the
page segment identifier. If this value specifies a page segment identifier already loaded in the printer, an
exception occurs.
Note: Because page segments use more than the normal amount of printer storage, use page segments
only when data needs to be kept.
Include Page Segment (IPS)
Length D67F Flag Correlation ID (Optional) DATA
The Include Page Segment command causes a previously stored set of commands to process in the input
data stream as though they were just received from the host. The printer places the segment at the
current presentation position and updates the presentation position as a result of this command.
