Hello, @MTOrthodox. Thanks for taking the time to add your question here on the PayPal Community Forum.
The PayPal Zettle card reader requires a mobile device and an internet connection or cellular data connection. It is not designed to be used with a computer. However, there are accessories that you may purchase in addition to a card reader, such as a cash register, printer, etc.
Please check out https://www.paypal.com/us/smarthelp/article/compatible-smartphones-and-tablets-for-paypal-zettle-faq... for compatibility information and please check out https://www.paypal.com/us/business/pos for information on all Zettle, including the additional hardware/accessories you may purchase.
I hope this is helpful. Thanks for your interest in PayPal Zettle!
Sincerely,
Michael
