Transmit Status Identification N - Epson TM-U375 User Manual

1. When printing on a single cut sheet that is narrower than the
carriage
cut sheet mode and the sheet of paper has been inserted, the
following operations should be avoided: turning the power
supply switch on or off, opening the cover, issuing the return
home command (ESC), or sending a reset command through the
interface.
When the carriage moves away from the home position, it may
come in contact with the left end of the paper, causing a paper
jam.
2. The cut sheet waiting state can be canceled by the DLE ENQ 3
command.
3. Use the ASB function to correctly determine the paper state. See
Example Print Control for Cut Sheet later in this section.
Transmit Status Identification
The values of specific bits are fixed in the status information transmitted
by the printer, so that the status bytes of commands can be identified. The
user can therefore confirm the command to which the status belongs, as
shown in the following table.
When using Auto Status Back (ASB), however, process the consecutive
three-byte code (except for XOFF) as ASB data after confirming the first
byte of the ASB. Otherwise, the status transmitted by using the command
and the status of the second and following bytes of the ASB cannot be
differentiated.
