[. . . ] Note that 0AH is defined as a command (LF). As a result, the data string that is actually processed is: 30H, 31H, 32H, 0AH, 33H 4. 3. 2 Undefined commands If the data following ESC (1BH) or GS (1DH) is not defined as a command, then the two bytes (ESC/GS and the code that follows) are read in and discarded. Example: 30H, 1BH, 22H, 31H, 32H If the above data string is input, the printer discards the data 1BH and 22H as undefined commands. As a result, the data string that is actually processed is: 30H, 31H, 32H 4. 3. 3 Settings outside the defined range If a value outside of the defined range is input for a command that takes parameters, that command is ignored and the previous value for that setting remains unchanged. In the case of a command that takes multiple parameters, command processing is halted the moment that a value outside of the defined range is input and subsequent values are processed as normal data. Example:1BH, 52H, 15H If the above data string is input, 1BH and 52H are defined as a command (ESC R), but the parameter 15H is outside of the defined range. As a result, the printer reads in and discards the data string 1BH, 52H, 15H. Accordingly, the previously set international character set is not changed. 2002. 8. Programmer's Guide 17 COMMANDS 4. 4 Command descriptions HT [Name] [Format] Horizontal tab ASCII Hex Decimal HT 09 10 [Description] [Notes] Moves the print position to the next horizontal tab position. This command is ignored unless the next horizontal tab position has been set. Horizontal tab positions are set with ESC D. The default tab positions are at intervals of 8 characters (columns 9, 17, 25. . ) for the font B (12×12). [Reference] ESC D LF [Name] [Format] Print and line feed ASCII Hex Decimal LF 0A 10 [Description] [Note] [Reference] Prints the data in the print buffer and feeds one line based on the current line spacing. This command sets the print position to the beginning of the line. 8. Programmer's Guide 18 COMMANDS CR [Name] [Format] Print and carriage return ASCII Hex Decimal CR 0D 13 [Description] [Note] [Reference] This command prints the data in the print buffer and does not feed the paper. Sets the print starting position to the beginning of the line LF DLE EOT n [Name] [Format] Real-time status transmission ASCII Hex Decimal 1 n 4 Transmits the selected printer status specified by n in real time, according to the following parameters: n = 1: Transmit printer status n = 2: Transmit off-line status n = 3: Transmit error status n = 4: Transmit paper roll sensor status [Notes] This command should not be used within the data sequence of another command that consists of 2 or more bytes. For example, If you attempt to transmit ESC 3 n to the printer, but DTR (DSR for the host computer) goes to MARK before n is transmitted and then DLE EOT 3 interrupts before n is received, the code <10>H for DLE EOT 3 is processed as the code for ESC 3 <10>H.

[. . . ] Drawer kick-out connector pin 3 status enabled. On-line/off-line enabled Error status disabled. Undefined. Even if only one of the statuses is enabled, the status is sent when this command is executed. Subsequently, whenever the state of a valid status changes, that status is sent. [. . . ]
