2. COMMAND DETAILS
2.1. Explanation of Terms
• Reception buffer
The buffer for storing data (reception data) received from the host, as it is called the reception buffer.
Reception data is temporarily stored in the reception buffer, then processed sequentially.
• Line buffer
The buffer for storing image data for printing is called the line buffer.
• Line buffer full
The state in which the buffer has no more space available is called line buffer full. When the buffer is full in standard mode,
data in the line buffer is printed and a line feed is performed when new print data is processed. This is the same as a Line
Feed. When the line buffer is full in the page mode, the printer move the print position to the head of the next line then starts
with the new print data.
• Top of line
The top of line is a state that satisfies the following conditions.
- There is currently no print data in the line buffer.
- The position is not specified with the horizontal direction position command.
• Printable region
This is the maximum printable area with the printer’s specifications.
• Print region
This is the printing area specified by a command. (Print region ≤printable region)
• ANK character base line
* For SM-S and T series, the base line is the upper end of each data.
• ASB Function
Sends the automatic status to the host each time the printer’s status changed.
• NSB Function
When the printer uses a parallel I/F or USB I/F, sends the automatic status each time the reverse transfer mode is entered.
When the printer uses Ethernet I/F or wireless I/F, sends the automatic status when the printer is connected to the print port
(TCP#9100). The ASB and NSB status formats are the same.

2.2. Exception Processing
1) Undefined codes
Codes from <00>H to <1F>H are targeted. When codes not defined as commands in this region are received, they are
discarded.
(Ex.) If processing the data string of <30>H<31>H<03>H<32>H<0A>H<33>H, the printer will discard <03>H as an
undefined code.
2) Undefined commands
When data continuing the codes of ESC, FS, GS, DLE are codes not defined as commands, ESC, FS,GS and subsequent
codes are discarded.
(Ex.) If processing the data string of <30>H<1B>H<22>H<31>H<32>H, the printer will read and discard <1B>H<22>H as
an undefined command.
3) Settings outside of the defined area
Processing values outside of the defined area in commands accompanying arguments, those commands are ignored and
the preset values are unchanged.
(Ex.) If processing the data string of <1B>H<52>H<15>H, the printer will discard the data string of <1B>H<52>H<15>H
because although <1B>H<52>H is defined as a commands (ESC R), the argument <15>H is outside of the
definition. Therefore, the international character set that is already set experiences no change.
