With the CMP-30, you can conveniently print receipts up to 3 inches wide while on the go. The CMP-30 offers the same advanced Bluetooth and Wi-Fi technology, as well as a robust construction, as the smaller CMP-20 mobile printer. This ensures fast and easy printing with a drop-in paper loading mechanism, paper end indicator, simple paper guidance to prevent jams, and a built-in tear bar to cut the paper to the desired length.
