Section 5. Interface Specifications

If a CAN (18 hexadecimal) is received by the printer, it will cancel the current print job and clear all data from the receive buffer.

Status Response

The Bi-Com protocol is an advanced version of bi-directional communications where the printer can also report the number of labels remaining to be printed for the current print job. Upon receipt of an ENQ command, the printer responds with nine bytes of status information bounded by an STX/ETX pair. The Bi-Com protocol works only in the Multi Job Buffer mode. The status information is defined as follows:

<STX>{ 2 Byte ID}{1 Status Byte}{6 Byte Label Remaining}<ETX>

ID - This is a two byte number identifying the current print job ID. The print job ID is defined using the <ESC>ID Job ID command transmitted with the print job (see Job ID Store in the command listing for more information on how to use this command). The range is from 00 to 99.

Status - A single byte defining the current status of the printer.(see the Status Byte Definition table on Page 5-8).

Label Remaining - Six bytes defining the number of labels remaining in the current print job. The range is from 000000 to 999999 labels.

If an ENQ is received after the print job specified in the ID bytes has been completed, or there is no data in the buffer, the printer will respond with two “space” characters (20 hexadecimal) for the ID number and six “zero” characters (30 hexadecimal) in the Remaining Labels bytes.

If a CAN (18 hexadecimal) command is received , it will stop the print job and clear all data from the receive and print buffers. A delay of five milliseconds or more is required before any new data can be downloaded. The CAN command is effective immediately upon receipt, even if the printer is off-line or in an error condition. The printer will return an ACK (06 hexadecimal) if there is no printer error condition and a NAK (15 hexadecimal) if an error condition exists.

Upon receipt of a valid print job (<ESC>A . . . <ESC>Z), and ACK (06 hexadecimal) will be returned by the printer if there are no errors and a NAK (16 hexadecimal) if a printer error exists.
