It seems that the current EPSON normal ESC/POS printer/device driver/EPSON's library does not have a right-to-left printing function.

There seems to be an example of taking special measures for a specific version of a specific environment, but it is not something that can be applied to other environments.
Arabic Font Printing via OPOS Printer (EPSON TM-T88V)

Probably, as a countermeasure with the smallest amount of data, create only the Arabic character part as bit image data to be printed with the ESC * command, create the ASCII character part as text, and send them in combination. Will do.

However, TM-P60II does not seem to support the ESC * command.
In that case, you will only be able to use one of the following methods.

GS ( L / GS 8 L
GS D

Programmatically, it would be easy to create all the contents including ASCII and Arabic characters as one bit image data, send it, and print it.
However, the printing speed seems to be slow.

Alternatively, it is possible to determine the presence or absence of Arabic characters on a line-by-line basis, print text data if only ASCII characters are included, and create and print as bit image data if Arabic characters are included.
It's not recommended as the ASCII fonts will be disjointed, but it will be a bit faster than printing everything as a bit image.

For example, is the escpos-php library prototyped with such an issue?
However, it seems that it has not been officially implemented.

Alternatively, you could try printing with character encoding by implementing your own inversion of sentences containing Arabic characters, as the Python library module does in this article.
