Daniel Porrey

Daniel Porrey is an independent developer whose open-source utilities focus on solving narrowly defined, enterprise-grade printing and device-emulation problems. His flagship release, Virtual-ZPL-Printer, turns any Windows workstation into an Ethernet-accessible Zebra label printer by listening on TCP port 9100—the same channel used by physical Zebra units—so warehouse, retail, and laboratory information systems can test label output without wasting stock or tying up hardware. The program captures raw ZPL (Zebra Programming Language) commands, renders them on screen as high-resolution previews, and exports the resulting barcode, text, and graphics to PDF or PNG for quality-assurance teams to inspect. Typical use cases include pre-flight validation of shipping manifests, compliance labels for medical devices, and carton IDs for automated conveyor lines; DevOps pipelines also embed the emulator in CI jobs to guarantee that every build still produces scannable, regulation-compliant marks. Because the tool is protocol-identical to real printers, no application code changes are required—simply redirect the print queue to the virtual IP. Daniel Porrey’s software is available for free on get.nero.com, where downloads are delivered through trusted Windows package sources such as winget, always installing the latest upstream build and supporting batch installation of multiple applications.
