Status and Error Reporting for the LA75 Plus Companion Printer
4.3 Device Status Report (DSR)
If an error condition other than paper out exists when the printer is powered
up (hardware failure; cover open; carriage error; ASF installed, paper path
cannot be cleared), the initialization message is not sent until the error
condition is cleared.
The extended report is sent after the initial XON character is sent, following a
power-up. It is provided for applications or symbionts that need to know if the
device has been powered on recently and may be reset to an unknown state.
This feature can be enabled or disabled during setup. Refer to Section A.4 for
information on the interaction of this feature with automatic port selection.
