SRP-500 DLE ENQ n [Name] Real-time request to printer [Format] ASCII DLE ENQ n Hex 10 05 n Decimal 16 5 n [Range] n = 2 [Description] The printer responds to a request from the host specified by n. n = 2: Recovers from an error after clearing the receive and print buffers. [Notes] This command should not be used within the data sequence of another command that consists of two 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 DLE ENQ 2 interrupts before n is received, the code <10>H for DLE ENQ 2 is processed as the code for ESC 3 <10>H. This command n = 2 is valid only when a mechanical error or an auto-cutter error has occurred. DLE ENQ 2 enables the printer to recover from an error after clearing the data in the receive buffer and the print buffer. The printer retains the settings (by ESC !, ESC 3, etc.) in effect when the error occurred. The printer can be initialized completely by using this command and ESC @. This command is enabled only for errors that have the possibility of recovery ESC SP n [Name] Set right-side character spacing [Format] ASCII ESC SP n Hex 1B 20 n Decimal 27 32 n [Range] 0 ≤ n ≤ 255 [Description] Sets the character spacing for the right side of the character to [ n x 0.122 mm {1/208 inches}] . [Notes] The right-side character spacing for double-width mode is twice the normal value. [Default] n = 0 ESC ! n [Name] Select print mode(s) [Format] ASCII ESC ! n Hex 1B 21 n Decimal 27 33 n [Range] 0 ≤ n ≤ 255 [Description] Selects print mode(s) using n as follows:

When the Least Significant Bit (LSB) is 0, the user-defined character

SRP-500 set is canceled and the internal character set is enabled. When the LSB is 1, the user-defined character set is selected. [Notes] When the downloaded character set has been released, the internal character set is specified automatically. [Default] n = 0 [Reference] ESC &, ESC ? ESC & y c1 c2 [x1 d1...d(y x x1)]...[ xk d1... d(y x xk)] [Name] Define user-defined characters [Format] ASCII ESC & y c1 c2 [x1 d1...d(y x x1)]...[ xk d1... d(y x xk)] Hex 1B 26 y c1 c2 [x1 d1...d(y x x1)]...[ xk d1... d(y x xk)] Decimal 27 38 y c1 c2 [x1 d1...d(y x x1)]...[ xk d1... d(y x xk)] [Range] y = 2 32 ≤ c1 ≤ c2 ≤ 255 0 ≤ x ≤ 14 (Font A) 0 ≤ x ≤ 12 (Font B) 0 ≤ d1 ... d(y x x) ≤ 255 [Description] Defines user-defined characters. y specifies the number of bytes in the vertical direction. c1 specifies the beginning character code for the definition, and c2 specifies the final code. When only one character is desired, use c1 = c2. x specifies the number of dots in the horizontal direction. [Notes] Consecutive character codes for multiple characters can be defined in one definition. When specifying only one character, specify c1 = c2. "d" is definition data that indicates the pattern for " x" dots in the horizontal direction starting from the left edge. If " x" does not satisfy the number of dots in the character configuration pattern, the remaining dots on the right are spaces. The number of bytes required to download a character definition for one character is " y" x " x". In the definition data, a "1" represents a dot that is to be printed, and a "0" represents a dot that is not to be printed. Independent downloaded character definitions are possible for each font. The font is selected by the "ESC !" command. The defined downloaded characters are cleared in the following circumstances: 1) When "ESC @" is executed 2) When deleted by "ESC ?" 3) When the printer is reset or turned off [Default] The internal character set [Reference] ESC %, ESC ? ESC * m nL nH d1...dk [Name] Select bit-image mode [Format] ASCII ESC * m nL nH d1...dk Hex 1B 2A m nL nH d1...dk Decimal 27 42 m nL nH d1...dk [Range] m = 0, 1 0 ≤ nL ≤ 255

SRP-500 0 ≤ nH ≤ 3 0 ≤ d ≤ 255 [Description] Selects a bit-image mode using m for the number of dots specified by nL and nH Divide the number of dots to be printed by 256. The interger answer is nH and the remainder is nL. Therefore, the number of dots in the horizontal direction is calculated by nL + 256 x nH. If the bit-image data input exceeds the number of dots to be printed on a line, the excess data is ignored. d indicates the bit-image data. Set a corresponding bit to 1 to print a dot or to 0 to not print a dot. The bit-image modes selectable by m are as follows. m No. of Vertical Dots Dot Density Adjacent Dot Maximum number of dots 0 8 Single Density Permitted 252 1 8 Double Density Permitted 504 [Notes] If the values of m and nH are out of the specified range, the following data is processed as normal data. After printing a bit image, the printer returns to normal data processing mode. The relationship between the image data and the dots to be printed is as follows. ESC - n [Name] Turn underline mode on/off [Format] ASCII ESC – n Hex 1B 2D n Decimal 27 45 n [Range] n = 0, 1, 48, 49 [Description] Turns underline mode on or off, When n = 0 or 48, underline mode is turned off. When n = 1 or 49, underline mode is turned on. [Notes] Underlines can be printed for all characters, but not for the space set by HT. This command and ESC ! turn underline mode on or off in the same way. If n is out of the specified range, this command is ignored. [Default] n = 0 [Reference] ESC !, ESC 2 [Name] Select default line spacing

SRP-500 [Format] ASCII ESC 2 Hex 1B 32 Decimal 27 50 [Description] Selects default (1/6-inch) line spacing. [Reference] ESC 3 ESC 3 n [Name] Set line spacing [Format] ASCII ESC 3 n Hex 1B 33 n Decimal 27 51 n [Range] 0 ≤ d ≤ 255 [Description] Sets the line spacing to [ n x (1/192)] inches. [Default] n = 32 (1/6 inch) [Reference] ESC 2 ESC < [Name] Return home [Format] ASCII ESC < Hex 1B 3C Decimal 27 60 [Description] Moves the print head to the standby position. [Notes] The leftmost end is detected by the home position sensor. Since the home position is detected when this command is executed, the printing position may shift after this command is executed. ESC = n [Name] Select device [Format] ASCII ESC = n Hex 1B 3D n Decimal 27 61 n [Range] n = 1 [Description] Selects device to which host computer sends data. n = 1 ; enable n = 2 ; disable [Default] n = 1 ESC ? n [Name] Cancel user-defined characters [Format] ASCII ESC ? n Hex 1B 3F n Decimal 27 63 n [Range] 32 ≤ n ≤ 255 [Description] Cancels user-defined characters. [Notes] This command cancels the pattern defined for the character code specified by n. After the user-defined characters is cancelled, the corresponding pattern for the internal character is printed.

SRP-500 This command deletes the defined pattern for the specified code in the character font selected by the "ESC !" command. If a user-defined character has not been defined for the specified character code, the printer ignores this command. [Reference] ESC &, ESC % ESC @ [Name] Initialize printer [Format] ASCII ESC @ Hex 1B 40 Decimal 27 64 [Description] Clears the data in the print buffer and resets the printer mode to the mode that was in effect when the power was turned on. [Notes] The DIP switch settings are not checked again. The data in the receive buffer is not cleared. ESC D n1... nk NUL [Name] Set horizontal tab positions [Format] ASCII ESC D n1...nk NUL Hex 1B 44 n1...nk 00 Decimal 27 68 n1...nk 0 [Range] 1 ≤ d ≤ 255 0 ≤ k ≤ 32 [Description] Sets horizontal tab positions. n specifies the column number (counted from the beginning of the line) for setting a horizontal tab position. k indicates the total number of horizontal tab positions to be set. [Notes] The tab position is set at [character width x n] from the beginning of the line. The character width includes the right-side space of the character, and is twice the normal value when double-width is specified. This command deletes horizontal tab positions that have already been set. When "n = 8" has been set for the horizontal tab position, the printing position moves to the ninth digit when HT is executed. Up to 32 tab positions can be set. Data exceeding 32 tab positions is processed as normal data. Input k in ascending order and place a NUL code <00>H at the end when k is less than or equal to the preceding value k-1, tab setting is finished and the following data is processed as normal data. ESC D NUL cancels all horizontal tab positions. The previously specified horizontal tab positions do not change, even if the character width changes. [Default] The default tab positions are at intervals of 8 characters (columns 9, 17, 25, ...) for the font B (12 x 14). [Reference] HT

SRP-500 ESC E n [Name] Turn emphasized mode on/off [Format] ASCII ESC E n Hex 1B 45 n Decimal 27 69 n [Range] 32 ≤ n ≤ 255 [Description] Turns emphasized mode on or off. When the LSB of n is 0, emphasized mode is turned off. When the LSB of n is 1, emphasized mode is turned on. [Notes] * Printing is slower in emphasized mode. Only the lowest bit of n is enabled. The printer does not emphasize bit-images. This command and ESC ! turn on and off emphasized mode in the same way. The last proceeded command becomes effective. Printer output is the same in double-strike (ESC G) and in emphasized. [Default] n = 0 [Reference] ESC !, ESC G ESC G n [Name] Turn double-strike mode on/off [Format] ASCII ESC G n Hex 1B 47 n Decimal 27 71 n [Range] 0 ≤ n ≤ 255 [Description] Turns double-strike mode on or off. When the LSB of n is 0, double-strike mode is turned off. When the LSB of n is 1, double-strike mode is turned on. [Notes] * Printing is slower in double-strike mode. Only the lowest bit of n is enabled. The printer does not double-strike for bit-images. Printer output is the same in double-strike and in emphasized (ESC E). [Default] n = 0 [Reference] ESC E ESC J n [Name] Print and feed paper [Format] ASCII ESC J n Hex 1B 4A n Decimal 27 74 n [Description] Prints the data in the print buffer and feeds the paper [ n x 0.122mm {1/192 inches}] . [Notes] After printing is completed, this command sets the print starting position to the beginning of the line. This command has no effect on the line feed amount set by the "ESC 2" command or the "ESC 3" command.

SRP-500 [Notes] 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. In this case, because the current state is shown for each status, there is a possibility of a state change for a status for which ASB is not enabled. If all statuses are disabled, the Automatic Status Back (ASB) function is disabled. When transmitting a status, the printer transmits only four bytes. Four bytes of status data must be consecutive, except for XOFF code. This command is executed when the data in the receive buffer is developed. Therefore, there may be a time lag between receiving this command and transmitting the status, depending on the receive buffer status. When the printer is disabled by ESC = (Select peripheral device), this command is disabled but ASB is not disabled. The status to be transmitted are as follows: First byte (printer information) Bit Off/On Hex Decimal Status for ASB 0 Off 00 0 Not used. Fixed to Off. 1 Off 00 0 Not used. Fixed to Off.

SRP-500 [Notes] ASB(Automatic Status Back) transmits the status such as ink near-end, ink cartridge installed/not installed automatically to the printer in real-time. It is called [ASB function] and the status is [ASB status]. If you use ASB, application can acquire the printer change in real-time and passively. Enabling any status (except n =0) starts ASB. Then the current ASB status is transmitted. After that, when ASB is active, the selected enabled ASB status is transmitted each time the status changes. When n = 0, ASB is disabled. During ASB is disabled, ASB status is not transmitted. ASB status for ink is 4-byte, consisting of [header + status A + status B + NUL]. Header is [Hexadecimal = 35H/Decimal = 53] Status A : Bit Function Binary Hexadecimal Decimal Ink near-end not detected (1st color) 0 00 0 0 Ink near-end detected (1st color) 1 01 1 Ink end not detected (1st color) 0 00 0 1 Ink end detected (1st color) 1 02 2 Ink cartridge installed (1st color) 0 00 0 2 Ink cartridge not installed (1st color) 1 04 4 Ink cartridge installed (2nd color) 0 00 0 3 Ink cartridge not installed (2nd color) 1 08 8 4 Reserved - - - Cleaning is not being performed 0 00 0 5 Cleaning is being performed 1 20 32 6 Fixed 1 40 64 7 Fixed 0 00 0 Status B : Bit Function Binary Hexadecimal Decimal Ink near-end not detected (2nd color) 0 00 0 0 Ink near-end detected (2nd color) 1 01 1 Ink end not detected (2nd color) 0 00 0 1 Ink end detected (2nd color) 1 02 2 2~5 Reserved - - - 6 Fixed 1 40 64 7 Fixed 0 00 0 ASB is enabled if any status item is selected.
