Extended Report Meaning
ESC [ 0 n ESC [ ? 20 No error
ESC [ 3 n ESC [ ? 24 ; 26 n Printer offline; cover open
Some errors, including all that require operator intervention, trigger
unsolicited error reports when they occur, if unsolicited error reports are
enabled. (In a shared environment, any action that would block a printer
queue requires notification of the host system.)
The LA600 maintains a minimum of 30 error conditions. When the error buffer
is full, a status message is stored in a status message buffer for transmission.
If another event occurs and the transmission of the previous message did not
start within a timeout of 600 milliseconds, the new message buffer is skipped.
As soon as the interface is enabled, a message stored in the status message
buffer is transferred. In any case, therefore, the power-on status message is
transmitted.
