A label printer can be economical and practical for even a low volume seller. They are reliable, labels look professional, and keeps your regular printer free for other document printing. Plus they print all kinds of other labels as well.
For USPS only the small narrow width low cost printers like the Dymo 450, is all you need. For USPS, UPS, FedEx, you need a larger printer than does 4"x6" labels like the Dymo 4XL. Plus this size can be used for Packing Slips as well. They also make WiFi ones, but those can get expensive.
Besides the Dymo, there are options offered by Zebra, Rollo, Seiko, and others, but I prefer the Dymo for the cost and range of labels available. You can buy low cost labels right here on ebay, just look for an approved compatible from a USA seller. Cheap imports can be problematic.
One word of caution, do not buy the new Dymo 500 series, 550, or 5XL. They are not compatible with many label types.
