Include Page Segment (Ips); Delete Page Segment (Dps); Delete Font (Df) - IBM 6400 Programmer's Reference Manual

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
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.
The DATA field is two bytes in length and can be any value between X

defined in the printer causes an exception to occur.

The Delete Page Segment command deletes (clears) either a single page
segment or all page segments from the printer memory.
