Label printers come with multiple connectivity choices—and choosing the right one for your workflow can save you integration headaches, improve uptime, and streamline printing. Below, we break down the most common options with real-world specs from Citizen models offered by Crane Distributors.
Standard Connectivity Options Explained
USB (Wired USB 2.0)
Most desktop models, like the Citizen CL‑E300, CL‑E303, and CL‑E321, include USB as a staple interface, ideal for direct connection to a PC or POS device. Reliable, secure, and straightforward.
Ethernet / LAN
Printers such as CL‑E300, CL‑E303, and CL‑E321 include built‑in 10/100 Ethernet ports. Perfect for workgroups or shared label stations on networks.
Wi‑Fi (Wireless LAN, 2.4 GHz/5 GHz)
Many Citizen printers, particularly the CL‑E303 can be optionally outfitted with Wi‑Fi via an interface module for 802.11 b/g/n support. Allows flexibility to install printers where wired access isn’t practical.
Bluetooth (Wireless Point-to-Point)
Some models, like the CL‑E303EX version, include Bluetooth support, useful for mobile POS or temporary setups where USB or network wiring is impossible.
