Theory of Operation
The Arabic printer is equipped with a built-in front end analyzer that preprocesses all incoming data from
a host before it is sent to the LinePrinter Plus emulation. This front-end analyzer has two functions:
1. Cross-emulation: Translates all incoming commands from the host to the LinePrinter Plus
emulation.
2. Arabization: Processes all incoming printable characters from the host and Arabizes them
line by line.
This figure shows the printer shows where the Front End Analyzer resides in the data stream. Data is pre-
processed by the Analyzer before it is handed over to the LinePrinter Plus printer emulation.
