I want a very cheap and very compact solution to print return labels when I am returning goods bought online.
Is there anything like that?
Yes, Brother makes a few and Dymo makes a few.
They are all awesome and I recommend them highly for everyone. They are thermal printers so they use special labels (not very expensive) and don't use ink, which makes them very reliable and cheap and fast and small. They connect via usb to your pc and come with free app to help you type the labels.
Maybe pick up an older used model on ebay for cheap.
Just search for: dymo label printer
or: brother label printer
