See discussion #issues/71 you probably need to cancel the default printer characters, send the pos commands for this

I read about searching in the manual for hex characters, i did find them but now what? I'm sorry but I'm totally new in working with printers

I think you did not read the whole discussion, there are the snippets of code that were tested with base64, which would be the one here

but my case is different because I'm not seeing Chinese and my printer is not the same as his mine is EXTECH S3750THS

CesarBalzer commented 5 years ago

Your case is different but the printer and POS, so you should see in the manual of your printer which are the characters to set the encoding and the type of characters, then mount a javascript with the commands of your printer as I showed in the pastebin link and do the tests.

If you get this code there is the link and run what happens?

sorry, today I'm running at work, I edited the last link in the paste, please test it again, the correct function was missing and you did not even notice it.

i noticed and changed it and the above image is the output of the correct code and idk if this means anything but even the simple english text isnt printing correctly, it is printing arabic letters

CesarBalzer commented 5 years ago

so you should change the character encoding, I did this directly in java, now you have to go changing and testing as I did, here in Brazil we use iso 8859 1, if you notice java is setting this, maybe if you change it help, I even uploaded a commit in the morning altering it, I commented the lines that the encoding was setting. Sorry if I could not help you anymore
