5-3-3 Automatic Status Auto status is a group of states that are automatically returned from the printer to the hos t when the printer's status has changed. Automatic status is composed of "Header 1," "Header 2" and "plurality of bytes of the printer status" and is continuously returned to the host. The host always uses an identifying method to identify the data for every byte received. (It is possible that Xon/Xo codes are exceptionally mixed in the auto status in the Xon/Xo mode (when using a serial I/F), so it is necessary to consider that on the receiving side.) The valid/invalid conditions of the auto status abide by the DIPSW or the memory switch settings for the initial values. It is possible to change the conditions using the ESC RS a n command after turning ON the power. Also, it is possible to get the auto status using the ESC ACK SOH command, regardless of the valid/invalid conditions. 1. Header 1 Header 1 is the 1 byte length information tr ansmitted at the head of the automatic status. The table below shows the composition of the Header 1. Header 1 represent s the entire status transmission byte count, including Header 1, using bit 1 to bit 3 and bit 5. The host gets the transmission byte information and always receives the status data for that amount transmission bytes. For reference, the table below shows the relationship of actual transmission bytes and the Header 1. Because the bit 0 that indicates that this is the Header 1 is normally 1 (the second byte and beyond is 0), to detect the Header 1, it is acceptable to verify that bit 0 is 1 and bit 4 = 0 for this data. Note that bit 6 is for future expans ion and is ignored in host-side processes.

Automatic Status
Auto status is a group of states
that are automatically returned from the printer to the hos t when the printer’s status has
changed. Automatic status is composed of
"Header 1," "Header 2" and "plurality of
bytes of the printer status" and is
continuously returned to the host. The host always uses
an identifying method to identify the data for every byte
received.
(It is possible that Xon/Xoff codes are exceptionally mixed in the auto status in the Xon/Xoff mode (when using a serial
I/F), so it is necessary to consider that on the receiving side.)
The valid/invalid conditions of the auto status abide by the DIPSW or the memory switch settings for the initial values.
It is possible to change the conditions using the ESC RS a n command after turning ON the power.
Also, it is possible to get the auto status using the ESC ACK SOH command, regardless of the valid/invalid conditions.
1. Header 1
Header 1 is the 1 byte length information tr
ansmitted at the head of the automatic status.
The table below shows the composition of the Header 1. Header 1 represent s the entire status transmission byte
count, including Header 1, using bit 1 to bit 3 and bit 5.
The host gets the transmission byte information and always
receives the status data for that amount transmission bytes.
For reference, the table below shows the relationship of
actual transmission bytes and the Header
1. Because the bit 0 that indicates that
this is the Header 1 is normally 1
(the second byte and beyond is 0), to detect the Header 1, it is acceptable to verify that bit 0 is 1 and bit 4 = 0 for this
data. Note that bit 6 is for future expans ion and is ignored in host-side processes.
