Printer Status Commands
Read Status
Returns the status of the printer.
Printable data sent to the printer immediately after this command is not
included in the print process or data buffer status.
If the printer is not processing data, but data is buffered, then the printer is
holding a partially formed line and is waiting for the user to complete the line
before it is printed. The forms compensation assembly is not opened while the
printer holds a partial line of data.
The data buffer status reflects the state of the data buffers only, not the
communication buffers.
