user84155: I want to generate my own QR code with my main cryptocurrency addresses without using an online solution, is there maybe a command prompt way or particular piece of software I cam download for this, many thanks.
Also please move to correct section if this is in the wrong place

user26873: You could use offline JS libraries either with your browser or in your console.
Command Prompt
Requires NodeJS & NPM to be installed
npm install -g qrcode-terminal
qrcode-terminal '1SomeCryptoCurrencyAddressOrPK'
Offline in Browser
Or in your browser with an offline library
Save a copy of the raw qrcode.js file to your computer as a javascript file. https://raw.githubusercontent.com/davidshimjs/qrcodejs/master/qrcode.js
Then simply use it within an html file
<html>
<script src="qrcode.js"></src>
<div id="qrcode"></div>
<script type="text/javascript">
new QRCode(document.getElementById("qrcode"), "1SomeCryptoCurrencyAddress");
</script>
</html>
