Label printers

Thermal label printers are required to print bar-coded labels for bin locations and
products without UPC codes. We recommend the Direct Thermal Zebra ZD420D
with 203 DPI print resolution and with a 10/100 Ethernet port for network
installation.

Label Size
Our bin location, product, and staging labels are designed for 2.5” x 4”, making it our recommended option. Please do not order alternate sizes without checking with DDI Support first.
Printer Support
DDI System provides support for the model(s) listed above. Alternate printers with support
for the EPL print language may be compatible, though DDI cannot guarantee this nor
provide extensive troubleshooting.
Direct Thermal vs Thermal Transfer
The Direct Thermal is recommended for most users for its cost effectiveness. For more
durable labels or harsher environments (extreme temperatures or outdoor use) consider a
Thermal Transfer model instead.
Wireless access points

A strong wireless signal must cover the entire warehouse. Look for access points designed for warehouse environments. These typically include connectorized antennas, scalability, and Power over Ethernet (PoE).
Proper antenna configuration is critical to ensure network stability and prevent dropouts. It’s advisable to test signal strength and connection prior to implementation.
