POS printers use legacy code pages, but data is usually found in a modern encoding like UTF-8.
This database allows developers to handle this conversion gracefully, to get printers speaking your language.
This data was by the open source POS community, to help improve their own printing experience.
By contributing to this database, you can improve software compatibility for the printers that you use.
Some printers emulate a limited ESC/POS command set.
By using this database, you can develop software that sends the right commands to ESC/POS printers from any vendor.
