Specification
(STANDARD)
• This command should not be used within the data sequence of another
command that consists of 2 or more bytes.
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 then DLE EOT 3
interrupts before n is received, the code <10>H for DLE EOT 3 is processed
as the code for ESC 3 <10H>.
• When Auto Status Back (ASB) is enabled using the GS a command, the status
transmitted by the DLE EOT command and the ASB status must be
differentiated. Refer to Appendix C, Transmission Status Identification.
• This command is ignored when the printer is deselected by set peripheral device
command, ESC =.
• The printer transmits the current status. Each status is represented by one-byte
data.
