Global Graphics’ Harlequin Embedded SDK provides printer and multi-function peripheral (MFP) manufacturers with high-performance components for PDL interpretation and rendering on their choice of embedded controller.
The Harlequin Embedded SDK processes PostScript®, PDF, PCL and XPS natively on a wide range of controller architectures and operating systems. It’s scalable so that OEM partners can deploy native PDL solutions across all their products using a common architecture.
Configurable support for multiple PDL formats, a compact and efficient software kernel, and sophisticated graphics and color handling routines ensure the Harlequin Embedded SDK delivers the ideal software solution for embedded controllers. It is suited for a vast array of devices including both monochrome and color printers and Multi Function Printers (MFPs).
Implementation options range from OEMs utilizing comprehensive SDK documentation with support via Global Graphics’ Technical Services team, to a full integration service which gives access to our dedicated embedded development team who provide custom API deliverables that are specific to OEM requirements, as well as on site customer support.
Typical embedded system software architecture
- True native PostScript®, PDF, PCL and XPS interpretation without conversion first to another format. OEMs may choose to take all these PDLs, or any combination and build them into a single solutions. For specific PJL implementations OEMs should contact Global Graphics with their requirements
- Modular architecture enabling small footprint and low memory requirements
- Highly flexible APIs facilitating easy integration of OEM or 3rd party intellectual
- Color management
- Font handling
- Extensive programmatic configuration language for:
- PDF interpretation (PostScript, PDF, PCL, XPS)
- Transparency support
- Color management
- Screening: AM, FM, HDS (Harlequin Dispersed Screening), Custom
- Disk and diskless operation, with the ability to use a RAM-based file system if required
- Device resident font support
- Emulation of body text fonts in single-byte scripts, and facilities for font substitution
- Support for a wide range of print resolutions, bit depths, color models and interleaving and frame raster format styles.
- Cross-platform support.

- Code size ranges from 3.5MB for a single PDL (PostScript or PCL) to 8.5MB for all 6 PDLS - This excludes resources and is based on a Windows build. Embedded targets are generally larger, dependent on processor and compiler.
- Resources are typically 4MB for PostScript and up to 25MB (uncompressed) for all 6 PDLs. These are configurable depending on resources such as fonts, and are normally compressed and built into for Embedded platform builds.
- Working RAM is a minimum of 25MB for PostScript with a typical range of 45MB to 128MB for multiple PDLs.
