Frequently Asked Questions
- Will these 4" x 6" mobile printer labels fit my printer?
- These are designed for mobile thermal printers that accept 0.75" core rolls — Zebra ZQ520, ZQ521, ZQ620, ZQ630, QLn220, QLn320, QLn420, ZQ110, Brother RJ-3050, RJ-3150, RJ-4030, RJ-4040, RJ-4230B, RJ-4250WB, Honeywell RP2, RP4, MP Compact 4, and similar handheld and belt-clip mobile printers. Verify your mobile printer supports 0.75" core rolls and the standard 4" wide mobile shipping label format. Most field-service, route-delivery, and warehouse mobile printers in the 4" wide class are compatible with 4" x 6" on 0.75" cores.
- What's the difference between mobile 4" x 6" and desktop 4" x 6" labels?
- Mobile 4" x 6" labels use a 0.75" inner core to fit handheld and belt-clip mobile printers, which have smaller media compartments than desktop printers. The label facestock, adhesive, and print quality are identical to the desktop version — only the core size and roll outer diameter differ. Don't load 1" core rolls into a mobile printer; the spindle won't fit.
- Are these compatible with USPS, FedEx, UPS, and Amazon shipping platforms?
- Yes. 4" x 6" is the standard shipping label format for all major US carriers and platforms — USPS, FedEx, UPS, Amazon, eBay, Etsy, Shopify, ShipStation, Pirate Ship, and others. The labels print barcodes, QR codes, and tracking data from any of these systems with proper printer configuration.
- Do I need a ribbon?
- No. These are direct thermal labels — the printer's thermal head creates the image directly on the heat-sensitive label. Ribbons are only needed for thermal transfer printers, which mobile printers typically don't support.
