2. Overview
The 9400 Series Thermal Printer can receive print data online
from a host computer. During online communication, the host
computer treats the printer as an RS-232 type printer. For the
printer to communicate online, you will need an RS-232 cable.
For mainframe communication, you may need a protocol
converter.
To transmit data from the host computer requires
communication controls for the download operation. Refer to
the next section, "Communication Requirements."
Three types of data can be transmitted:
Format data
Batch data
Graphic data
NOTE: Format, batch, and graphic data are stored when you
turn the power off.
Format and graphic data may be sent at any time.
Since batch data is combined with a format for printing, the
format and graphic data for a batch must reside in the printer
before sending the batch.
The user-designed layout for online
formats. These formats are used by online
batches for printing.
NOTE: These online formats can also be
used offline. However, formats
