tranhung148 commented 5 years ago

i was try pass param encoding "UTF-8" but didn't receive my expect

januslo commented 5 years ago

May i know what codeset your printer supports. I encode the bytes by GBK currently. My devices would cause issue while using UTF-8.

januslo commented 5 years ago

I found something shows UTF-8 would not resolve vietnamese problem neither.

It need some codding test for vietnamese but I cannot spare my time to it now.

Hey, is there a encoding where I can use the dolar sign? I'm from brazil, utf-8 really isn't working as expected.

Any thoughts on how can I proceed? I need to print phrases like "Preço R$ 5,00" and it prints "Pre?o R¥ 5,00" on encodings I've tried.

thankssss

gdierksmeier commented 5 years ago

You can play with SelfText and see if your printer accept the Portuguese....(codepage) BluetoothEscposPrinter.printText( "Preço", { encoding: 'Cp037', codepage: 3, widthtimes: 0, heigthtimes: 0, fonttype: 1 } ); You can find encoding here: https://docs.oracle.com/javase/8/docs/technotes/guides/intl/encoding.doc.html

Boa sorte.

Try this

BluetoothEscposPrinter.printText( "İŞÖÇİşiçöğü awd awdawdaad --**? \r\n", {
  encoding: 'Cp1254',
  codepage: 22,
  widthtimes: 0,
  heigthtimes: 0,
  fonttype: 1
} );

Other options: Cp857, Cp1256, Cp1026

Hello, didn't want to make new issue ticket so I'll just ask here. Which encoding should I use for Croatian lagnuage? We are using latinic letters with addition of ć,č,š,ž and đ.

As others mentioned UTF8 or UTF-8 for encoding doesn't seem to work.

Or if you could point me to all the encodings supported so I can test them till I find suitable one.

Best regards, Bepo.

hello , which encoding should i use for printing Arabic text ?

anyone ? please.

gdierksmeier commented 5 years ago

We are using: ENCODING: ISO8859_6 CODEPAGE: 22

All depend of your printer...try also the combinations: "encoding": "Cp1256" or "encoding":" Cp864" with CODEPAGE: 22 or 32

mg4u commented 5 years ago

@Iamstanlee did you get the Arabic encoding?

mg4u commented 5 years ago

The best solution I find out is, Build your receipt in View component and style it as you like, do not forget to make the background of the view "white", and use "react-native-view-shot" to convert the view to an image then printPic by Bluetooth printer. Hope this helps.

alimasarra commented 5 years ago

hi, its printing arabic, but its printing it in the inverse way, like: علي مسرة its printing it ةرسم يلع any solution for that? and i am using these ENCODING: ISO8859_6 CODEPAGE: 22

alimasarra commented 5 years ago

fixed it by adding this.reverseString before the text

mg4u commented 5 years ago

@alimasarra could you add snippet code?

BluetoothEscposPrinter.printText("Tiếng việt nè đm chúng m\n\n", {encoding: 'Cp1258',codepage:30});

@gdierksmeier I found Cp1258 and codepage 30 nearly display Vietnamese characters, are there any option? my device is Mini thermal printer 5802DD
