Critical Rendering Defect in AirPrint: Systematic failure of text quality on Canon MF660C Series

I am writing to formally complain about a critical rendering defect in macOS AirPrint that systematically degrades the professional output quality.

Despite using a high-end Canon MF660CDW Driver printer, the AirPrint driver fails to render text vectors correctly, resulting in jagged pixels and non-uniform line weights. This issue is not present when using manufacturer-specific drivers, proving that the flaw lies entirely within Apple’s AirPrint rendering engine.

As a professional user, I find it unacceptable that Apple promotes "driverless printing" while delivering sub-standard, pixelated results that look like low-quality 72dpi images. This is not a "generic trade-off"; it is a failure to meet the basic standards of modern desktop publishing.

I demand a technical investigation into how AirPrint processes text on macOS and a software update to ensure vector-based text integrity for professional-grade hardware like the Canon MF660C series. Stop sacrificing quality for the sake of convenience.

iMac 24″, macOS 26.4

Hi!

AirPrint is a universal, driverless printing system built on Apple's CUPS framework. It converts do***ents into generic raster images before sending them to the printer, which destroys vector text precision. Printer-specific features like high-resolution text rendering, color profiles, and fine toner control are all unavailable through AirPrint

Solutions

Install the Canon official driver
Go to System Settings → Printers & Scanners → Add Printer, and manually choose the installed Canon driver instead of the auto-selected AirPrint option.
Remove the existing AirPrint-registered printer, then re-add it after installing the Canon driver.
Apply the latest firmware for the Canon MF660C to improve macOS compatibility.
Enter the printer's IP address manually and connect via IPP to fully utilize the dedicated driver without AirPrint.

AirPrint is a convenience protocol, not a professional-grade print solution. Switching to Canon's dedicated driver is the most reliable fix for text quality issues.
