A mechanism for integrating print quality enhancement (PQE) and multi-bit halftone data is disclosed. A system of embodiments of the invention includes a print control unit communicably coupled to a printer, the print control unit operable to process received multi-bit input print data for printing by the printer. The system further comprises a PQE card communicably coupled with the printer, the PQE card configured to separate multi-bit text and line art input data from multi-bit halftone image input data in the multi-bit input print data, ignore any of the identified multi-bit halftone image input data for purposes of applying PQE technology to the identified multi-bit halftone image input data, and apply the PQE technology to the identified multi-bit text and line art input data. Lastly, the system includes a print head communicably coupled to the printer, the print head operable to print multi-bit output created by the PQE card.
