Sample implementations of an IPP Client, Proxy, Server, and other tools.
The ippsample project provides sample, non-production-ready implementations of IPP Clients, Printers, and Proxies. It makes use of the CUPS Library v3 and PDFio library projects to provide low-level HTTP, IPP, and PDF support. The ippserver and ipp3dprinter code was also inspired by the original CUPS ippeveprinter source code. The project also includes two transform programs, ipptransform for 2D printing and ipptransform3d for 3D printing, as well as a "lint" program (ippdoclint) for validating document data in automated test environments.
The server implements most IPP standards including IPP Everywhere™ and includes transform support for 2D and 3D printing. A beta snap is available for Linux systems.
The IPP Sample Code is developed and distributed as open source software under the Apache License, Version 2.0. Contributions should be submitted as pull requests on the Github site. Developer guidelines can be found in the file DEVELOPING.md.
The ippdoclint program validates document data in a variety of formats, allowing for automated testing of IPP clients.
The ippproxy program implements a generic IPP Proxy interface that allows you to connect a local IPP, PCL, or G-code printer to an IPP Infrastructure Printer such as the ippserver program.
The ippserver program implements most IPP standards and is commonly used for prototyping and automated testing. It provides a generic IPP Printer interface that allows you to share printers locally or using the IPP Shared Infrastructure Extensions. Printers can be configured to use authentication and/or to provide transforms using the included or third-party programs. A scriptable web interface allows for a variety of automated testing opportunities.
The ipptransform program is a generic file conversion utility that is used primarily with ippserver to support rasterization of JPEG and PDF documents for IPP Everywhere and HP PCL printers.
The ipptransform3d program is a generic file conversion utility that is used primarily with ippserver to support slicing of STL and 3MF documents for 3D printers connected via USB.
