foo2oak-wrapper

The foo2oak-wrapper command is a print filter wrapper designed for use with the foo2zjs printer driver.

It acts as an intermediary between the Common Unix Printing System (CUPS) and the actual foo2zjs ghostscript (gs) based printer driver, handling tasks such as pre-processing the input data stream, selecting appropriate color profiles, and passing necessary parameters to the driver.

Specifically, the wrapper enables printing on printers requiring the OAK (Optimized Architecture for Konica) protocol, facilitating communication between the print job and the printer's rendering engine. It essentially adapts standard print streams into a format the foo2zjs driver, and specifically the oak variant, can understand. It often handles color profiles and other necessary configurations to properly rasterize the incoming job.

This command ensures that printers supported by the foo2zjs driver, and specifically those implementing the OAK protocol, can be used within a standard Linux printing environment managed by CUPS. It is essential for proper printing with these printers.

This command is intended to be called by CUPS and usually not directly by a user.

CUPS configuration files typically specify the foo2oak-wrapper as the command to execute when a print job is sent to a printer using the foo2zjs OAK driver. The correct invocation of this wrapper from CUPS is crucial for correct printing.

The wrapper often handles applying the correct ICC color profiles to the job before passing to gs. These profiles can be critical for ensuring accurate color rendering by the printer.

The foo2oak-wrapper command was developed as part of the foo2zjs project to support printers using the OAK protocol. The foo2zjs project aimed to create open-source drivers for printers that lacked proper Linux support. The foo2oak-wrapper fills a specific need within that ecosystem, enabling standard CUPS print jobs to be rendered correctly on OAK protocol printers.
