Virtual Receipt & Label Printer Emulator

Features

• Its own public TCP port for every printer, permanent and assigned from the 9100 block
• ESC/POS protocol receipts and EPL protocol labels, parsed command by command with a real-time preview
• Prints from anything that talks to a network printer: POS software, a Windows or CUPS queue, a printing library, or a socket you open yourself
• Or import a captured dump — drop a binary file or paste a hex dump or base64 and see what it draws, with no application and no code
• Fault injection — paper out, paper near end, cover open, offline, error — set from the web interface or from a test, and the status the printer reports follows the state you put it in
• A modelled receive buffer with a configurable capacity and drain rate: a job that outruns it is marked with a buffer overflow, and the printer reports itself busy until the buffer drains
• Driven from automated tests over a REST API: create a printer, print to it over TCP, then read the parsed receipt back as JSON or wait for it on a live stream
• Multiple printers and paper widths per workspace, shareable across devices
