Hi there, usersharkasifresh.

Any printer can work as long as it connects to the device you're using to access QuickBooks Online. Then, all we have to do is find and open the sales receipt or any transaction you created. Once done, select the Print or Preview button and click Print.

You'll want to check this article for more details about setting up, adjust, or check the printing alignment: Print sales forms.

Keep on posting here if you need more help. We'll respond as soon as we can.
