STAR LIne Mode Command Specifications
5-2-4) Printer Status Transmission Specification when using Ethernet and Wireless LAN
Interfaces
The following explains the printer status transmission specification when using Ethernet and wireless LAN interfaces.
1)
Transmission format:
• When transmitting only STAR ASB:
STAR ASB (Second Byte Bit-7=1) + Length (Length = 0x0000)
• When transmitting printer status other than STAR ASB:
STAR ASB (Second Byte Bit-7=1) + Length + Status Data
Length + Status Data
Length + Status Data
• 2 byte value indicating status data byte count (0x0000 ≤ Length ≤ 0x0200)
• When the status data is 10 bytes: Length = 0x000a
• When transmitting only STAR ASB: Add Length = 0x0000
• When Star ASB Second byte Bit-7, and Length is added, Bit-7 = 1 is set.
For status analysis, the total byte count of ASB is detected using the first byte of Star ASB, and whether length is
added with the second byte Bit-7 of Star ASB is detected. By getting the byte count of subsequent status data using
the length, the status can be analyzed.
2)
Status Data Transmission Format:
Status Type + Delimiter 1 + Data Type + Status Length +
Printer Status + Delimiter 2
(1) Status Type (2byte or 4byte)
• First and second bytes
Indicate a factor of printer status occurring.
• “00”:
Reserved
• “01” to “09”:
Star real-time status request command
• “10” to “49”:
STAR Status Request Command
• “10” to “49”:
STAR Status Request Command
:
STAR Status Request Command
• “50” to “59”:
Reserved
• “60” to “99”:
Reserved
• “A0”:
MICR Function Command
• “A1” to “FF”: Reserved
• Third and fourth bytes
If the factor is the command, indicates the n parameter of the command.
If there is no n parameter, the third and fourth bytes can be omitted.
(2) Delimiter 1 (1 Byte)
Sends “:”.
(3) Data Type (1byte)
Indicates the data type of the printer status, and sends “B” (binary type).
(4) Status Length (2byte)
2 byte value indicating byte count of printer status
