Explanation
• Status is queued each time an event occurs.
• Status will change according to the events occurring asynchronously.
• A status size is fixed to 14 bytes.
• A status indicates the print job progress (the number of printed pages) as well as an error.
• The length of a response is variable, but it can be found by analyzing the part that follows the header.
• A response is queued.
• It is easy to judge whether a status or a response.
• A status is generated each time an error occurs or the printer completes printing a page.
• When no status or response remains in the send buffer, no data will be returned in response to the
status read.
In this case, ReadPort of the port monitor seems to return a successful reading, not an error.
