Frequently asked questions

Find answers to common questions about our ZPL and PDF conversion engine, pipelines, pricing, and integration.

How do I get started?

Sign up for a free account, get your API key, and make your first conversion in under 5 minutes. Check the documentation for quickstart guides.

What printers are supported?

zplflow converts between PDF and ZPL. ZPL output is compatible with all Zebra thermal printers and any printer that understands ZPL commands.

Where does my data go?

zplflow is stateless, no data is persisted. For async jobs, data is deleted after 8 hours (configurable to 0). All data is processed in the EU on a European cloud provider.

What happens if I exceed my plan?

With dynamic over-budget enabled, the service continues working. You can enable or disable this in your settings. Overage is billed per 1,000 labels at a slightly higher rate.

Can I use zplflow for GDPR-compliant label processing?

Yes. Stateless architecture means no data traverses borders. We're EU-hosted on a European cloud provider.

Can I use zplflow with my existing ERP or WMS?

Yes. zplflow works alongside your current software without any changes. Your ERP sends labels as it always has, and zplflow converts, transforms, and fixes formats in between. No migration, no consultants, no changes to your existing systems.
