• After the print changing line operation ends, paper sensor status
(n = 1, 49) is transmitted. Therefore if use GS r 1 according to the
printing instruction, host recognizes the print completion by
receiving paper sensor status.
• Normal status can be differentiated by the information of bits 4, and 7
from other transmission data. If the data transmitted from the printer
after outputting GS r to the printer is “0xx1xx10”(x = 0 or 1), process the
data as a normal status.
• When the paper roll cover is open, paper detection (detected by the
paper roll end sensor) may be incorrect.
• When n is out of the specified range, the command is ignored.
• When DTR/DSR RS232C communications handshaking control is selected,
the printer transmits the one-byte response only when the host signal
DSR indicates it is ready to receive data.
• When XON/XOFF RS232C communications handshaking control is
selected, the printer transmits the one-byte response regardless
of the host signal DSR.
