Frequently Asked Questions

Everything you need to know about viewing Datamax DPL labels with LabelZoom.

What is DPL?
DPL here means Datamax Printer Language — the command language of Datamax (later Datamax-O'Neil, now Honeywell) thermal printers such as the E-Class, I-Class, and M-Class lines. It's not related to other things abbreviated DPL (like the Delphi language or various 'display list' formats): if your file came from a warehouse label printer, it's Datamax DPL.
How do I view a DPL label without a Datamax printer?
Paste the DPL commands into the viewer above and click Quick Preview. LabelZoom's engine interprets DPL natively and renders the label on screen — one of the only tools anywhere that can, since almost every online label tool is ZPL-only.
Why does my WMS produce DPL, and can I still preview it?
Warehouse systems generate the printer language of the hardware they were configured for — sites running Datamax/Honeywell fleets produce DPL print streams. Capture the stream (or export the template) and paste it here to preview labels without touching a production printer.
We're replacing Datamax printers with Zebra hardware. Now what?
That migration is exactly where LabelZoom's multi-format engine helps: it reads your existing DPL and writes modern formats, so templates don't have to be redrawn from scratch. The REST API automates this at fleet scale — talk to us about migration tooling.
