There are many possible encodings.

• All printers has many encoding formats so one language can come with more than one format.
• Print test command to see what the default printer codepage, so select the equivalent required Lang codepage.
  • For example: default printer codepage start with ISO- then you should select your Lang codepage that start with ISO- .
  • Test command will print codepage table used by printer, so you can know it
  • In printer codepage table thier is a sequence for each codepage, this sequence should be sent to printer before sending any text to set its codepage, then encode the text with the equivalent codepage "not sequence".
• But their is a limitation for RTL Languages such as Arabic: Letters are separated & Left sequence ordered! So result will be terrible!
• The only solution "according my knowledge" is convert receipt to image then send image to printer.
• Easiest way is using webview to capture image then sending it to printer.

astreams1.Write(Array As Byte(0x1D, 0x28, 0x41))

astreams1.Write(Array As Byte(0x1B, 0x74, 40))
'set page code arabic
'note: 40 is the sequence number of arabic codepage - it may vary from printer to another
'note: we don't send codepage

astreams1.Write("مرحبا بكم".GetBytes("ISO-8859-6"))
'we set codepage here
