This instruction returns the x- and y-coordinates of two diagonally opposite corners of
the current plottable area. Four ASCII-coded integers indicating the lower left and upper
right corner coordinates are returned by using the following format:
X , Y , X , Y
LL LL UR
LL: lower left
UR: upper right
KC-GL uses device-control instructions to return buffer status information and other sta-
tus information from the printing system via the RS-232C interface. Status information
cannot be output on the parallel interface. If device-control instructions are received via
the parallel interface, they are ignored.
The device-control instructions for status output appear below.
This instruction returns 0 if the receive buffer is full, and 1024 if the receive buffer is
empty.
This instruction normally returns 0, if an error has not occurred, and returns 15 if a fram-
ing error, parity error, or overrun error has occurred.
This instruction always returns the value 1024.
This instruction returns printing system status information regarding:
• On-line status
• Cover open
• Paper empty
• Paper jam
• Buffer full
The following table describes this status information.The paper feed source is the inter-
nal cassette at all time. A complete list of device-control instructions appear in Device-
Control Instructions on page 113.
