Self Test Printing
If the ON-LINE switch is pressed at power-on and held until the initialization opera-
tion ends, a given pattern is printed repeatedly. During printing, the printer is in the
OFF-LINE state. To terminate printing, press the ON-LINE switch until the printing
stops. When the switch is released, the printer performs the initialization operation,
enters the ON-LINE state, and the ON-LINE lamp goes on.
If paper-empty or cover-open is detected, printing is terminated while the printer is
still in the OFF-LINE state. When printing is terminated due to a paper-empty condi-
tion, the P.EMP lamp is lit, the buzzer sounds for 3 seconds, and the P.EMP signal
is output. This state can be reset by loading paper and pressing the RESET or ON-
LINE switch once. The printer then starts the initialization operation and enters the
ON-LINE state. If the RESET or ON-LINE switch is pushed though no paper has been
inserted, the printer enters the OFF-LINE state, the P.EMP lamp lights, and the buzzer
rings for 3 seconds after executing the initialization operation.
When printing is halted because of a cover-open condition, the printer performs ini-
tialization and enters the ON-LINE state only after the printer cover is closed and the
RESET or ON-LINE switch is pressed.
The self test print examples in the two modes (Epson Printer and IBM Graphics Printer)
are shown on pages 15 and 16.
Automatic Printing
When data input exceeds one line of data, printing is automatically carried out without
a print command unless the data are graphics data; there is no automatic print signal
with graphics data. After automatic printing,
the printer is in the same condition as
it was prior to printing except when the
function is cleared.
Bold Printing
In order to create bold print, a 1/120 inch dot is printed to the right of the initial dot.
