Busy line and fault conditions

Chapter 5: Programming commands 91

To guard against this situation, the application must determine the cause of a busy condition and take appropriate action or pace the real time commands to avoid filling the buffer. There is a minimum of 256 bytes available in the printer’s buffer when it goes busy.

If the printer is in error condition (cover is open, paper is exhausted…), the printer will still accept data, respond to the batch mode status commands (1B 76 and 1B 75 0), handle the cash drawer commands, and not go busy until it actually tries to execute a print command. Then it will stay busy and stop processing data out of the receive buffer until the condition clears. It will respond to the real time commands as described below.

Real-time status transmission

	GS sequence		DLE sequence
ASCII	GS EOT n		DLE EOT n
Hexadecimal	1D 04 n		10 04 n
Decimal	29 4 n		16 4 n
Value of n:	GS/DLE sequence
	1	= Transmit printer status
	2	= Transmit RS-232C busy status
	3	= Transmit error status
	4	= Transmit receipt paper status
	5	= Slip paper status
	6	= Validation paper status

Transmits the selected one byte printer status specified by n command within a few msec according to the following parameters. This command includes two sequences: GS (1D) and DLE (0×10).

Exceptions

The command is ignored if n is out of range.

An application using DLE (0×10) sequence must send EOT within 100 milliseconds of DLE or the printer will misinterpret the DLE and execute a clear printer command. Avoid this possibility by using the ID 04 n sequence, which is handled exactly the same as 10 04 n.

Unlike the A756, that had a dedicated connector and resultant dedicated status reporting for each cash drawer, the A776 has a single connector that shares data reporting from either cash drawer. When either cash drawer is open, an open status is reported by the printer.
