Issue with different escpos version

I have installed this package via yarn add escpos, of which the latest released version in Github is 2.4.4. However, the version which got installed is 2.5.2, as is in this repository's master package.json.

Also, the odd thing is that even though the Github master version and my installed version of escpos's package.json is same (i.e., 2.5.2), but I have found some missing code in printer.js. Meaning some of the code which is present in this repository's printer.js is not present in the printer.js installed in my pc.

Eg.
This is in the [repository's printer.js](this.width = options && options.width || 48;), which is not in my installed version of printer.js.
this.width = options && options.width || 48;

How can I correct this?

Vergleiche das veröffentlichte v2.4.4-Paket, die package.json und printer.js des Repositorys im master-Zweig sowie die im Bericht beschriebenen installierten escpos-Dateien. Ermittle, welches veröffentlichte Artefakt oder welche Versionsmetadaten abweichen, dokumentiere die Diskrepanz und verifiziere, dass das installierte Paket dem Inhalt der vorgesehenen Veröffentlichung entspricht.
