11 MODES OF OPERATION
The Ap1400 has two operating modes, when not actually printing:
"Idle Mode": ready to accept data, but no data are in the buffer awaiting printing, and the
printer motor is not running;
"Spool Mode": active, but storing data for later printing.
Modes are indicated by different colour combinations on the front-panel LED (see section 8).
11.1 IDLE MODE
In idle mode, the printer is ready to receive data, which will be printed as soon as complete lines or
graphics patterns are decoded. It responds to the paper feed button in the normal way, and can also
produce a demonstration print (see below).
11.2 SPOOL MODE
In spool mode, data is received and stored, but not printed. This is useful when printing needs to be
suppressed during data transfer (for example in mobile radio systems); or when the printer is unable
to print because the paper has run out or the lid is open.
The Ap1400 will automatically enter spool mode when the paper is out, when the head is up, or if
some other error condition occurs, or alternatively by command from the host. Spool mode may be
cleared by host command, automatically when the condition is cleared, or by "double-clicking" the
feed button.
