Transmit Printer ID

Transmits the printer ID specified by n. This command is a batch mode command; that is, the response is transmitted after all prior data in the receive buffer has been processed. There may be a time lag between the printer receiving this command and transmitting the response, depending on the receive buffer status.

When Auto Status Back (ASB) is enabled using the Enable/Disable Automatic Status Back command (1D 61), the status transmitted by this command (Transmit Printer ID) and the ASB status must be differentiated according to the information found in Recognizing Data from the Printer, (in the Real Time Commands section in this document).
