line data is received within 14 ms, the print speed of the printer drops and
does not achieve the rated print speed.
If the control code
or
the Paper Instruction signal is received without print
data,
the printer does not print and only feeds forms. If the received print
data is more than 132 or 136 bytes (one of them is selectable), data of the
133rd,
137th or higher byte is ignored. If the received print data is less
than 132 (or
136)
bytes, the remaining data is printed as spaces.
The print operation above is shown in Figure 4.2.

4.2 Interface Signals
This section explains the interface signal functions and physical
specifications.
4.2.1 Interface signal lines
Table 4.1 explains the OPC-compatible interface signal lines. Figures 4.3 a
4.4 show the timing chart of this interface and the timing specifications in
data transfer respectively.
This printer has a print data buffer
(PDB)
for 136 characters. While a WMR
signal and Online signal are being generated, print data is received according
to the Figure 4.3. Printing starts after the following control code or Paper
Instruction signal is received.
