The printer status to be sent to the host computer are ;
Device status changes - printer cover open, paper jams, paper out, etc
Job status changes - completion of the printing of a job, receiving a JOB command
Page status changes - ejecting a printed page
All the unsolicited status information (USTATUS DEVICE, JOB, PAGE and TIMED) is turned off at once
by the USTATUSOFF command. Each status can be turned off individually by the corresponding
USTATUS command.
The USTATUS TIMED command specifies after which time period the printer sends the unsolicited status
information and is turned off by setting the time increment to zero with this command.
To get information about the current settings or possible settings for unsolicited status, use the INFO
