Epson FX dot matrix printer fonts

This directory contains fonts for the Epson FX printers. While these were not extracted from original hardware or firmware, they have been checked carefully against matrices given in original documentation. The variants here correspond to different editions of the manual, as referenced in the files.

Should you however find any discrepancies with the sources references, or have access to other versions or sources of these fonts, please do get in touch.

Character sets

The characters are stored in ROM in an ASCII-based order, with non-ASCII characters filling the positions of control characters. The lower 7-bit block contains the roman slant of the font, while the upper block has the italic slant.

The printer supported different national character sets, which have some glyphs reassigned to different code points.

The following code points, and their corrresponding positions in the upper block, differ:

23 24 40 5b 5c 5d 5e 60 7b 7c 7d 7e
US # $ @ [ \ ] ^ ` { | } ~
Japan # $ @ [ ¥ ] ^ ` { | } ~
France # $ à ° ç § ^ ` é ù è ¨
Germany # $ § Ä Ö Ü ^ ` ä ö ü ß
UK £ $ @ [ \ ] ^ ` { | } ~
Denmark # $ @ Æ Ø Å ^ ` æ ø å ~
Sweden # ¤ É Ä Ö Å Ü é à ö å ü
Italy # $ @ ° \ é ^ ù à ò è ì
Spain $ @ ¡ Ñ ¿ ^ ` ¨ ñ } ~

Notes:

  • The lower-7 bit mappings are similar but not identical to either the ISO-646 variants or the DEC National Replacement Character Sets
