Research direction

Start with the printer.encode(...) calls and the iconv-lite SBCS encoding list shown in the reproduction. Determine which encoding path the target printer accepts, then verify output for the supplied Cyrillic and Azerbaijani strings; done means both character sets print without question marks.
