Barcodes and labeling 502 products

In readers, look at the reading type: linear (1D) readers read traditional barcodes, while image (2D) readers also read QR codes and those displayed on a mobile screen. Connectivity determines whether it is wired, with a wireless receiver or via Bluetooth, and for warehouse or outdoor use, the IP protection rating indicates how much dust and water it withstands.

In label printers, compare resolution and print speed: for small labels with fine text, higher resolution is better. For consumables and accessories, the "Compatible with" data in the product sheet indicates which devices they work with.
