FAQ

Frequently asked questions

Do I need a Zebra printer to use zplCloud?

No. You can design and preview labels as PNG, PDF and SVG in the browser without any hardware. Printing is available the moment you connect a printer - locally, via the Weblink relay or through a remote CLI agent.

How do remote printers work through a firewall?

A zplCloudCli agent runs on any machine in the printer's LAN (PC, Raspberry Pi, Synology, Docker) and opens a single outbound WebSocket connection to our backend - TeamViewer-style. No inbound ports, no port forwarding, no firewall changes on the customer side.

Which barcode symbologies are supported?

30+ verified symbologies including QRCode, DataMatrix, Pdf417, Aztec, MaxiCode, EAN/UPC, Code128/39/93, GS1-128, Postnet and Planet - all verified for correct ZPL output.

Does it support RFID / EPC labels?

Yes. The designer includes an RFID element for EPC Class 1 Gen 2 tags with the SGTIN-96 data structure - GTIN + serial are encoded to EPC hex with a full decode roundtrip, and output as ^RS / ^RB / ^RFW ZPL.

How does the Weblink relay keep connections alive?

The relay proactively probes every printer with ! U1 getvar "device.unique_id", tracks per-printer keepalive timestamps, cleans up duplicate connections and re-sends failed jobs from the queue.

In which languages is the platform available?

German, English and Portuguese. Light and dark themes follow your OS preference automatically and all UI strings live in a single translation dictionary.

The complete ZPL toolkit

Everything a label workflow needs, in one place

Visual designer, code roundtrip, printer tools, batch printing, webhooks, push notifications, certificate management and a hosted printing relay.

Visual design

Drag & drop label designer with mm ruler, grid, snapping and live preview. Text, barcodes, QR, RFID, images and shapes.

Instant preview

PNG, PDF and SVG rendered server-side from the exact ZPL the printer receives - nothing hidden, nothing guessed.

Direct printing

Send ZPL straight to Zebra printers via TCP 9100, the printer WebUI or the Weblink relay - queued or immediate.

Code roundtrip

Design → C# (ThermalLabel SDK) → Design, lossless and versioned. Generate, import and export real .NET console projects.

Batch processing

CSV / JSON data → thousands of labels, Chrome-style page-range selection, one-click print to any connected printer.

Integration

Webhooks with HMAC signing, ZPL-by-email and push to ntfy, Gotify, Signal, Telegram, WhatsApp and Web Push.

Remote fleet

On-premises printers reachable through the Weblink relay or outbound CLI proxy agents - no inbound ports, no firewall changes.

Trust & control

API keys, usage metering, per-host branding, team roles, Let's Encrypt TLS and ACME printer certificates.

CloudToBrowserPrint

Print directly from the browser and the cloud - on every platform

zplCloud2BrowserPrint is a local print service (127.0.0.1:9100) for Windows, macOS, Linux and Raspberry Pi: web pages find printers on the LAN and print ZPL, PDF, Office files, images and barcodes - directly from the cloud with the label designer, an alternative to CLI/Proxy and Cloud Connect: automated, in batch and without desktop software.

Device discovery - installed printers (Windows spooler), CUPS (Linux/macOS), network (TCP 9100) and Bluetooth - types individually filterable.
Printing - raw ZPL, URLs and files from the browser (multipart); multiple jobs in one request.
Conversion - PDF, Office (LibreOffice), images (TIF/JPG/PNG/…) and TXT → ZPL, optionally print directly.
Barcode decoding - images → recognized codes (ZBar; macOS: Apple Vision).
Bidi & IPP - TCP, serial, Bluetooth, parallel port and IPP, session-based like JSPM.
Print Server Mode - full functionality via SignalR WebSocket, live job trace, without a backend.

ZPL

Fully ZPL Freedom

We can do it all: fonts and graphics stored right on the printer, keeping payloads small. Everything is provisionable and manageable on your printers via our management tools - also per profile.

Anyone can send bulky PNG or PDF images with huge payloads to the printer. We can do that too - but we can also deliver performance when it comes to unique mass labels (e.g. RFID) that need to fly out of the printer.

SVG → TTF

Logos & icons as printer fonts

Mass bulk without the payload wall. Your logo and icons become one tiny TrueType font on the printer: upload the SVGs, we generate the TTF, push it once to exactly the printers you want - done. From then on every label carries a single glyph reference instead of kilobytes of graphics.

Your icon set, managed in zplCloud

1

Upload SVGs

Drop in your logo and icons - or build a new letter logo from a single letter.
2

We generate the font

Each icon becomes a glyph on a private Unicode code point (U+E000…). 3 glyphs ≈ 3 KB.
3

Update the printers - done

One click pushes the font to exactly the printers you select - per fleet or per profile. Every label that follows just works.

85× smaller - a 3 KB font uploaded once instead of ≈ 10.3 KB of graphics data in every single label
Built for mass bulk - 10,000 labels: ≈ 101 MB of GF data vs. ≈ 1.2 MB of text payload
Always current - icon changed? Update one font file, every label uses the new version immediately
Crisp & fast - vector outlines at any DPI (203 / 300 / 600), printed at text speed

Zebra printer tools

Direct printer control, down to the SGD level

Probe connectivity, read the full SGD configuration with German labels, browse the curated command database, upload files and fonts, and render previews through a real printer's WebUI.

Weblink relay

Printers connect outbound via WebSocket; ZPL is queued, kept alive and re-sent automatically on failure.

Remote agents

zplCloudCli proxy on any LAN machine - TCP 9100 or USB - opens one outbound connection. No inbound ports.

Certificate management

Root CA, server and per-printer certificates (NRD / PFX), 1-20 year validity, CRL revocation, one-click deploy.

Auto-reprint

Per-printer opt-in: failed jobs are reprinted automatically, straight from the queue.

How remote printing reaches the printer

Web app → REST POST /api/remote-printers/{id}/send

Backend invokes agent over open SignalR connection

Agent forwards ZPL → printer (TCP 9100 / USB)

Printer response → correlation slot → web UI

TeamViewer-style: the customer side only opens an outbound HTTPS/WSS connection - no firewall changes, no port forwarding, no inbound exposure.

RFID / EPC

Item-level RFID, ready for production

Encode and print RFID tags directly with zplCloud - EPC data structures, ASCII and HEX payloads on ZPL and Fingerprint printers, with the ecosystem of your choice.

Only available for ZPL & Fingerprint printers.

EPC data structures

SGTIN-96 and friends - GTIN + serial number become a 96-bit EPC hex, encoded and decoded right in the designer.

ASCII & HEX payloads

Write ASCII or raw HEX data to the tag - flexible for every workflow, from retail EAS to item-level logistics.

ZPL & Fingerprint printers

RFID items render natively on ZPL (select, write, read, erase) and Fingerprint printers - no extra hardware or middleware.

In-designer encoder

EPC / SGTIN-96 encode & decode with a full roundtrip - no external tools, no guessing.

Data bindings & batch

Bind tag data to CSV/JSON columns like any other field - thousands of RFID labels in one batch run.

Retail & logistics ecosystems

The printed tags work with the RFID infrastructure you already run - Nedap, Checkpoint, Sensormatic, Impinj and R-PAC are no problem.

ZPL write commands (EPC Class 1 Gen 2)

^RF - RFID write / read / erase

^XA
^RS8                    ; select EPC Class 1 Gen 2 tag
^RFW,H,1^FD3076215F0C5D974000000001^FS  ; write 96-bit EPC (SGTIN-96) as HEX
^RFR,H,1^FS             ; read back / verify
^XZ

Tags and EPCs generated by zplCloud integrate with the major EAS / RAIN RFID infrastructures.

FAQ

Frequently asked questions

Is zplCloud free?

Yes - the designer, all previews (PNG/PDF/SVG), the guides and the templates are free to use. Batch, webhooks and push only become paid with the Pro tier.

Can I preview ZPL like in Labelary?

Yes. The ZPL tab shows your code, the ZPL analyser explains every command, and the PNG/PDF/SVG preview renders the label exactly as the printer prints it.

Does zplCloud have an API like Labelary?

Yes - api.zplcloud.com with API keys, usage metering and OpenAPI docs at /api/scalar: /v1/fonts, /v1/zpl/* and /v1/printer-profiles.

How does zplCloud differ from Labelary?

Above all in the visual editor, the templates and guides, the language converters (EPL2/DPL/TSPL), direct printing to real printers as well as batch, webhooks and push - plus a modern, multilingual UI.
