6.8 Precautions
6.8.1 Notes on Product speed matching Feature Use
(1) If the product speed matching signal cannot be entered during printing, the printing
state continues to prevail so that communication may not be established (no
response can be made).
If such a situation is encountered, perform procedure or below.
Enter the standby state and then initiate the communication.
Issue the print abort code "DC3". After the IJ printer returns an "ACK"
response, perform the normal procedure to initiate the communication.
(2) Number of pulses necessary for a rotary encoder from print signal detection until
the start of printing.
Number of pulses necessary = Number of printing preparation pulses
( ) + Print start delay.
Number of printing preparation pulses = A / 1 scan time
Use an integer by rounding up the fractional portion.

6.8.2 Notes on Print Condition Transmission
(1) The number of digits for character height data is 2 by default. However, the
preceding IJ printer models GX and HX use 3 digits by default for print condition
transmission (optional function). If the new model of the IJ printer is used as a
replacement for such a predecessor, open the following screen from the
communication environment setup screen and change the number of digits for
character height data to 3.

● Character height (when the 3-digit data format is chosen)
Note: If the value is within the range from 100 to 999, an error occurs.
