Recognizing Data from the Printer
An application sending various Real Time and non-Real Time commands to which the printer responds can determine which command a response belongs to by the following table. Responses to ESC u and ESC v are non-Real Time responses and will arrive in the order in which they were solicited.
Note also that although the original intent of the response to ESC v was to provide error information in its one-byte response, the response up to now has always been Hex 00 when transmitted. This is because ESC v was not processed until the error condition was cleared. With the improvement to the busy line handling described earlier in this section, ESC v will be processed as long as there is not an error condition caused by trying to print with no paper or with the cover open.
