Chapter 3 — Extended Commands

Intermec Terminal Emulator (ITE) Programmer’s Reference Manual
VT/ANSI Data Stream
Due to possible system fragmentation of a data stream, the “#” in Line 1, Column 2,
should be the last character placed on the screen. This assures that all data is present
before the extended command is parsed (removed).
There are two ways to send the #F extended command. The conventional method
involves writing the command to the screen on line one, writing the data to be
printed on the second line, then writing a “#” character on the first line to activate
the print. The other method is to use the control characters APC (Application
Program Command) (0x9F) and ST (String Terminator) (0x9C) to encapsulate the
command. Using the control characters method is faster since they are not written
to the display.
The following table describes the line and columns where characters must appear,
and their meanings.
