2.8 Printing
1. Turn on the power to the printer and the computer.
2. Check that the ONLINE LED lights.
When the thermal paper is not set, the OFFLINE LED blinks. When
the thermal paper is loaded, the OFFLINE LED lights. Press the
ONLINE button so put the printer ONLINE.
3. Send a print command from the computer to the printer.
Example:
Printing ABC in parallel input using BASIC
1. Set SWDIP switch 1-1 to ON.
2. Input LPRINT "ABC" on the computer, then press the return key.
The printer should print ABC.
If the printer does not print, see Section 7, Troubleshooting.
HINT
• Some forms of BASIC use the PRINT# statement or the PR#
instead of the LPRINT statement.
2.9 Buffer Memory
The buffer memory, which has a capacity of about 28000 characters
(approx. 28KB), receives and stores data at high speed, greatly
reducing the time that the computer cannot be used while it outputs to
the printer. When the printer is ONLINE, data can be input during
printing until the buffer memory becomes full.
If the printer is turned OFFLINE when there is still data in the buffer
memory, the ONLINE LED will blink. Printing resumes when the printer
is turned ONLINE.
