6.2 Explanation of Terms
1) Real-time command
Real-time commands are identified with a DLE extension such as DLE EOT, DLE ENQ or DLE
DC4. The printer executes these commands as soon as they are received.

Obsolete commands are commands that will not be supported by future printer models. Therefore,
we recommend replacing them with more recent, upward-compatible commands that have the
same functions.

when the printer transmits data. The ESC/ POS handshaking protocol is required if the following
commands are executed:
GS ( C <some functions>
5) Print buffer

6) Receive buffer
The receive buffer is used to store data from the host PC. All received data is stored in this
buffer and processed in the order received.
7) The horizontal or vertical motion units
The horizontal or vertical motion units are used for calculating the setting values for various
commands and are [Horizontal direction: 0.159 mm {1/160"} / Vertical direction: 0.176 mm
