CHAPTER 5 CONTROL COMMANDS LIST GS a [Name] Enable/disable Automatic Status Back (ASB) [Format] ASCII GS a n Hex 1D 61 n Decimal 29 97 n [Range] [Default] 0 ≤ n ≤ 255 When DIP Switch or Memory Switch (BUSY condition) is Off: n = 0 When DIP Switch or Memory Switch (BUSY condition) is On: n = 2 [Description] Enables or disables basic ASB (Automatic Status Back) and specifies the status items to include, using n as follows: [Notes] 5-68 Bit Off/On Hex Decimal Status for ASB 0 Off On 00 01 0 Drawer kick-out connector pin 3 status disabled. 1 Drawer kick-out connector pin 3 status enabled. 1 Off On 00 02 2 Off On 00 04 0 On-line/off-line disabled. 2 On-line/off-line enabled 0 Error status disabled. 4 Error status enabled. 3 Off On 00 08 0 Paper sensor status disabled. 8 Paper sensor status enabled. 4 - - - Undefined. 5 - - - Undefined. 6 - - - Undefined. 7 - - - Undefined. ASB is the function that transmit the status of [cover open/close], [Online/ Offline] from the printer automatically. It is called [ASB function] and the status is [ASB status]. If you use ASB, application can acquire the printer change in a real-time and passively. Select any status enabled (except n = 0) and basic ASB starts. Then transmit the current basic ASB status. After that, while ASB is active the selected enabled basic ASB status is transmitted whenever the status changes. When n = 0, basic ASB is disabled. When ASB is disabled, basic ASB status is not transmitted. Multiple status items can be selected. When ASB is active, ASB status is transmitted whenever the status changes even if ESC = is not selected. This command setting is effective until ESC @ is executed, the printer is reset or power is turned off. During Block data [header - NUL] transmission, ASB is disabled temporarily. Therefore you cannot get the printer status change through ASB status when block data [header - NUL] is transmitted. Any basic ASB status represents the enabled status whenever the status changes. Therefore the disabled status items may change, because each status transmission represents the current status. The basic ASB statuses, corresponding to each bit for n are as follows: n ASB status Bit Function Bit Status Drawer kick-out 0 connector status. Bit 2 of the first byte Drawer kick-out connector pin 3 status Bit 3 of the first byte Online/ offline status. Bit 5 of the first byte Cover status. 1 Online/offline status.

Bit 2 and 3 of the third byte[Note] Paper end sensor status. Bit 2 of the second byte Mechanical error status. 2 Error status. Bit 3 of the second byte Auto cutter error status. Bit 5 of the second byte Unrecoverable error status. Bit 6 of the second byte Automatically recoverable error status. 3 Roll pap sensor Bits 0 and 1 of the third byte Paper near-end sensor status. status Bits 2 and 3 of the third byte Paper end sensor status. 6 Panel switch Bit 1 of the second byte status.
