![]() ![]() So to print the code pages 1, 2 and 3 to a binary file, the command would be: php escpos-character-tables.php 1 2 3 > code-page-1.bin This command-line tool then takes a list of code pages to inspect, and will output raw binary that generates a table like the one above when sent to the printer: php escpos-caracter-table.php NUMBER. You will generally find a list of code pages with a corresponding number for each one (0-255) in an ESC/POS printer’s documentation. That’s type of information you need when you’re asked about it on an issue tracker! Usage By printing it out, I can see that if I map single-byte half-width Katakana from Code, it will appear correctly in this code page. Today, I’ll share a small utility that can print out the contents of a code page, like this:Ī printer’s documentation vaguely labeled this encoding as “ Katakana”. ![]() The main open source drivers ( escpos-php and python-escpos) are both capable of auto-selecting an encoding, but they need a good database of known encodings to power this feature for each individual printer. Most commonly, non-ASCII characters are accessed by swapping the extended range to a different 128-character code page. I’ve been working on software that interacts with ESC/POS receipt printers for some time, and a constant source of trouble is the archaic character encoding scheme used on these printers. ![]()
