[Function] Transmission of printer status
[Code] < 1D>H<76>H
[Outline] [The specification which is common to the model]
Transmits current printer status.
[Caution] • Status is transmitted in 1byte with the content shown in the following table.
• In case of DTR/DSR control, only 1byte is transmitted after making sure the host is ready for
reception (DSR signal is in the Space state). In case of XON/XOFF control, only 1byte is
transmitted without checking the status of DSR signal.
• In case of DTR/DSR, if the host is not ready for reception (DSR signal in Mark state, wait till
reception is available.
• Paper-end status causes BUSY status, thus this command may be in the receive-not-ready status.
• This command is valid only when MSW3-7 is set to ON.
