I am trying to print some currency with Citaq v8 (it has a termal printer), but it prints ?, because of the printer character set.

I have byte array (UTF-8) data to print. But the printer has default some character set. How can I change the default character set programatically(like using byte array)? I need to change printer charset settings.

Device: Citaq v8 (the device has a termal printer) PS: I could not find any developer docs.

Perhaps UTF-8 is not supported as a character set/code table.

Even EPSON is supported only on some models.

You need to set the printer code page using the following two ESC/POS commands, and the character string to be requested for printing must be encoded and converted according to the code page before sending.

ESC t

Select character code table

ASCII   ESC t   n
Hex     1B  74  n
Decimal 27  116 n

ESC R

Select an international character set

ASCII   ESC R   n
Hex     1B  52  n
Decimal 27  82  n

Alternatively, you can create all the page contents to be printed with a Bitmap image and print it with one of the ESC/POS commands related to image printing.
However, it will be slow.
