Application Areas
This module is designed for ONLY draft-quality 9-pin dot-matrix texts. For NLQ or LQ texts, the OMNIFONT_PLUS2W, OMNIFONT_PLUS3W, OMNIFONT_MTX, OMNIFONT_FRX or OMNIFONT_MOR modules are likely to give better results.
Range of Characters
This module supports 76 languages, of which 14 have dictionary support: Catalan, Danish, Dutch, English, Finnish, French, German, Greek, Hungarian, Italian, Norwegian, Portuguese, Spanish and Swedish. It can read multiple languages. It can read 18 of the 29 punctuation characters. (The Low Double Comma Quotation Mark is missing). It supports 24 of the 55 miscellaneous characters. (Some missing ones are: the Euro Sign, the Small Script F, the Copyright Sign, Registered Trade Mark Sign and the Degree Sign.)
The following table lists all accented letters this module can recognize. The range of uppercase ones supported by this module is limited, since in 9-pin dot-matrix text, there is difficulty in printing these letters. Those with lowercase support only are listed separately:
|

Accuracy Issues
This module does not interpret the recognition trade-off setting.
Character Attributes
Since this module recognizes draft dot-matrix texts, character attributes are not applicable. Expanded characters are not recognized, condensed printout can be, but the accuracy is liable to be low.
Conditions
This module is used if it is directly specified in a zone structure.
If DRAFTDOT9 filling method is set together with AUTO, OMNIFONT_MTX is used, provided that all characters (or languages or filters) validated for the zone are supported by it. If any are not supported, this module is used.
It can generate confidence data on recognized characters and can interpret all filter values.
