Hi @Mfk759853063

nice, you discovered the command sequence that works on your printer.

I find some issues about beep on escpos-php from mike42
mike42/escpos-php#142
mike42/escpos-php#173
mike42/escpos-php#174

based on these issues:
-not all printer models have this feature.
-the (beep) command depends on printers model / not a pattern
I don't know yet the best whay of how to implement the beep, if it is good to configure on some text file or class enheritance.

The lib have some others similar commands that needs design attention, like "open cach drawer", "line feed" and "character table configuration".

I'm thinking about it.
