Unit 6: Bi-Directional Communications
PRINT START (SOH + DC1)
This command enables the printer to exit the pause mode by the request command to resume
printing. The host also sends an ENQ command to confirm execution. Execution should be
avoided while sending print or other data. Upon receipt of this command, an ACK is returned if an
error condition does not exist and a NAK if one does.
OBTAIN HISTORY DATA (SOH + LW)
This command enables the printer to send 500-items at a time of CR/LF history data to the host.
Avoid any transmission to the printer while history data is being sent to the host. Also avoid the
inclusion and use of this command in the print data.
When the Item Number command is not in the receive data, or the command is incorrect, the
item number is saved as "*****" and the status as "3" in the history. The Item Number Error may
occur at the beginning of print operation and cease operation.

RELEASE RETURN ERROR (SOH + SUB)
This command enables the printer to release from an error and resume printing of the item where
the error occurred. The host also sends an ENQ command to confirm execution. Avoid the
inclusion and use of this command in the print data.
PRINTER STATUS (SOH + MG)
Receipt of SOH followed by MG causes the printer to return information bounded by an STX-ETX
pair that reports the current operating status of the printer.
