Arabic Context Analyzer
The Arabic firmware offers outstanding performance in terms of Arabization features
and is intended for applications requiring Arabic and Latin high print quality under
different Arabization platforms. It supports many Arabization mechanisms and many
Arabic and Latin code sets.
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.
