are not provided, characters can be lost. There
are two ways to provide the required time delays:
1. By an actual time delay. This is preferred for
two reasons:
a. The time delay affords a period of time for
the Terminal to resynchronize.

quired time for a line feed or other operation.
In addition to the timing considerations of Table
3, certain operations of the TerlniNet 300 Printer
require a time delay to allo\v for completion of
execution. These time inte rvals are needed when
the Terminal is receiving data. If the tinle intervals
Table 4 and its examples indicate the required
time and/or fill characters that can be used to
provide the delays.
The paper tape reader on the
TermiNet 300 Printer automatically provides these
delays.

*Startup - The Tern1iNet 300 Printer will normally go from a non- printing or "Standby" state
to
a printing
or "On Line" state under code control. The two- code sequence for Motor On is ESC hor H. A time delay
of 420 ms should be allowec! before data transmission can begin,
A special version of the printer can be suppUec! where the printing motor will be commanded "On" when-
