Reliance Status

This command provides a wealth of information about the printers current status. The command will always receive a response unless the printer is offline (powered down, disconnected, etc.) or paper is actively being fed through the printer. A numeric argument is provided which controls the meaning of each bit in the returned byte(s). There is some duplication between fields for legacy support reasons but you effectively have access to all error and status conditions.
