Frequently Asked Questions
Does this configuration include Ethernet?
Yes. ZD4A042-30PE00EZ includes a 10/100 Ethernet interface as well as USB and USB Host.
Can I print through Bluetooth Low Energy?
BLE 5 is for printer setup through Zebra's mobile app. Do not treat it as Bluetooth Classic printing. This configuration is not the factory WiFi version.
What does 74 m or 300 m mean?
These are supported ribbon lengths in metres, not label widths. Choose a compatible ribbon width and core for the labels you use.
Do I need ink or toner?
No. Thermal transfer printing uses ribbon. Direct thermal mode uses suitable heat sensitive labels without ribbon.
Can it print a 100 mm wide label design?
Its maximum printable width is 104 mm. The full label and liner must also fit the media width and roll specifications, and your software template must match.
Is this the 300 dpi version?
