CHAPTER 5 CONTROL COMMANDS LIST ESC @ [Name] Command initialization [Format] ASCII ESC @ Hex 1B 40 Decimal 27 64 [Range] ------ [Default] ------ [Description] Initializes each command after printing data in the line buffer. DIP Switch is not reread. The following shows the specifications that are not initialized by this command. - DC1 and DC3 select/deselect status - ESC BEL external device drive conditions - Auto status valid/invalid conditions. ESC U n [Name] Select printing direction [Format] ASCII ESC U n Hex 1B 55 n [Range] [Description] Decimal 27 85 n 0 ≤n ≤1 48 ≤ n ≤ 49 ("0" ≤ n ≤ "1") Executes print direction specified by this command after printing data in the line buffer. N Print direction 0, 48 Specify bi-directional printing 1, 49 Specify uni-directional printing 5-120 ESC GS # m N n1 n2 n3 n4 LF NUL [Name] Set memory switch [Format] ASCII ESC GS # m N n1 n2 n3 n4 LF NUL Hex 1B 1D 23 m N n1 n2 n3 n4 0A 00 Decimal 27 29 35 m N n1 n2 n3 n4 0A 00 [Range] m = 87, 84, 44, 43, 45, 64 ( m = "W", "T 48 ≤N ≤ 57 ("0" ≤ N ≤ "9"), 65 ≤ N ≤ 70 ("A" ≤ N ≤ "F") 48 ≤ n1 ≤ 57 ("0" ≤ n1 ≤ "9"), 65 ≤ n1 ≤ 70 ("A" ≤ n1 ≤ "F") 48 ≤ n2 ≤ 57 ("0" ≤ n2 ≤ "9"), 65 ≤ n2 ≤ 70 ("A" ≤ n2 ≤ "F") 48 ≤ n3 ≤ 57 ("0" ≤ n3 ≤ "9"), 65 ≤ n3 ≤ 70 ("A" ≤ n3 ≤ "F") 48 ≤ n4 ≤ 57 ("0" ≤ n4 ≤ "9"), 65 ≤ n4 ≤ 70 ("A" ≤ n4 ≤ "F") [Default] ------ [Description] After defining the memory switches using the definition commands determined in the Class item of the table below, the memory switches are set by sending this write command. The printer executes a reset automatically after writing the setting values defined by the write command to the non-volatile memory. Do not turn the printer power off while writing to the non-volatile memory. If it is turned off, the memory switch settings will be corrupted and the settings may return to initial values where the offset value settings are a digit off from all the memory switch settings. Consider the life of the non-volatile memory and avoid over-use of this command.
