6.12 Printer Status Commands
These commands enable the printer to communicate with the host computer. They are stored in the printer's
data buffer as they are received, and are handled by the firmware in the order in which they were received.
When a fault occurs, the printer will go busy at the communication interface and not respond to either of
the Printer Status commands. If the fault causing the busy condition can be cleared, such as by loading
paper, or letting the thermal print head cool down, the printer will resume processing the data in its receive
buffer.
Real Time commands allow the printer to function when it is busy at the communication interface. See the
following section, Real Time Commands, for details about these commands.
