ASB (Automatic Status Back) Function Specifications Manual General Use Status This manual prescribes the general use status returned to the host. The general use status is composed of “header 1 + header 2 printer statuses” and is continuously returned. However, in the Xon/Xoff mode, because it is possible to mix both Xon and Xoff codes partway through the general use status, the host abides by an identification method, described later, to always identify data for each reception of 1 byte. The following provides a detailed description of the general use status. Enabling and disabling conditions of the automatic status abide by the setting of the memory switch and the DIPSW (refer to each printer manual for details). It can be changed using the “a” n command after turning ON the power. Header 1 Header 1 carries information regarding the length of one byte to be transmitted to the header of the general use status. The configuration of Header 1 is shown in Table 1 – 1. Header 1 represents the entire transmission byte count of the status using bits 1 to 3 and bit 5, including header 1. This value is added so that the host can correctly receive all data when changing the printer status byte count that accompanies an upgrade of the general use status. The host must correctly receive that many bytes. (The relationship between an actual transmitted byte count and Header 1 is shown in Table 1 – 2.) To indicate that this is header 1 of the header data, bit 0 is always 1 (subsequent bytes are always 0). Therefore, when detecting header 1, verify that bit 0 is 1. Also, because bit 6 is reserved for future expansion, the host ignores it. Table 1-1 Header 1 (First Byte) Bit Content 0 Always 1 Status 0 Status 1 – 1 2 Printer Status Byte Count 3 4 Always 0 – 5 Printer Status Byte Count 6 Reserved (Fixed to 0) – 7 Not Used (Fixed to 0) – Table 1-2 Corresponding of Actual Transmission Byte Counts and Header 1 Transmission Byte Count n Header 1 (7≤n≤15) 7 00001111B (0F Hex) 8 00100001B (21 Hex) 9 00100011B (23 Hex) 10 00100101B (25 Hex) 11 00100111B (27 Hex) 12 00101001B (29 Hex) 13 00101011B (2B Hex) 14 00101101B (2D Hex) 15 00101111B (2F Hex) Header 2 Header 2 carries the information of the length of one byte transmitted to second byte of the general use status. The configuration of Header 2 is shown in Table 1 – 3. Header 2 represents the version of the general use status (called general use status version below) using bits 1 to 3 and bit 5. (The relationship between the actual version and Header 2 is shown in Table 1 – 3.)

The configuration of the status is shown in Tables 1 (-5, -6, -7, -8 and -9) Printer status is returned by (transmission byte count – 2 by Header 1). Printer status is always updated to the latest information (no record exists). Also, refer to each printer specification manual for details on which are the contents of operation of each bit information (ex: recoverable errors). There are cases in which the content of the printer status is added when upgrading the version. Invalid is always handled as “0.” Table 1 – 5 Printer Status 1 (3rd Bit) BIT Contents Status 0 Status 1 SP298 SP2000 TSP400Z TUP492 TSP552II TSP800 TSP2000 TUP492Z 0 Always 0 1 Command Not Executed Executed Valid Valid Valid Valid Valid Valid Valid 2 Conversion Switch Status Open Closed Valid Valid Valid Invalid Valid Valid Valid 3 Online/Offline Status Online Offline Valid Valid Valid Valid Valid Valid Valid 4 Always 0 5 Cover Status Closed Open Invalid Invalid Invalid Invalid Valid Valid Valid 6 Offline by Pressing the Online Not Occurred Occurred Switch Invalid Valid Valid Invalid Invalid Invalid Invalid 7 Not Used (Fixed at 0) (*) Bit 1 is cleared to 0 when returned to the host.

(Enters “data exists” status when printer has bi-directional parallel interface.) How to Identify the Status The host can identify the status returned from the printer because the numerical values of specific bits are fixed, as shown in the table below. (However, it cannot distinguish the ENQ status between the general use status.)
