Describe the Phenomenon Below is one Canon printer's IPP capability. ipp_capability.txt

On Ubuntu22.04, use below command to create driverless ppd, the driverless PPD supports three filters: pdf/ufr/jpeg. driverless ipp://<ip-address> driverless_22.04.ppd.txt

*cupsFilter2: "application/vnd.cups-pdf application/pdf 200 -"
*cupsFilter2: "image/urf image/urf 0 -"
*cupsFilter2: "image/jpeg image/jpeg 0 -"

On Unbuntu23.10, use the same command to create driverless ppd, the driverless PPD only supports two filters: ufr/jpeg. driverless_23.10.ppd.txt

*cupsFilter2: "image/urf image/urf 0 -"
*cupsFilter2: "image/jpeg image/jpeg 0 -"

Driverless no longer supports pdf. Is this a degenerate bug or new specification?
