Hi, do you get this with every file you print? Try f.e. ```lp -d /etc/fstab``` I recall there is an expected slowness in ghostscript if transparent PDF is printed as...

Can you turn on debug logging, print again and attach the file with logs here?

Hi, thank you for reporting the issue! Would you mind turning on debug logging for CUPS, reproduce the issue and then attach file with logs here? Thank you in advance!

Hmm, both app and IPP backend sends the correct option and value - I've tested it with my home printer and Fedora 39 + CUPS 2.4.8, and DuplexNoTumble was applied...

@HROMANO If you run ```lpstat -l -e```, it lists available destinations, where the second word is the type of installation. The permanent queues are marked permanent, auto discovered/temporary ones are...

Ok - can you check whether cups-browsed is running and show printer options? ``` $ systemctl is-active cups-browsed $ lpoptions -p GARAGE_AIRPRINT -l $ lpoptions -p GARAGE_AIRPRINT ``` It would...

@HROMANO ahh, my bad - by screenshots I meant scans of printer outputs (printed papers) when you try to print DuplexNoTumble with 2.4.7 and 2.4.8 (original file would be great...

@HROMANO Ad provided data for now - good, I don't see any DuplexTumble (PPD option) or two-sided-short-edge (IPP attribute) in default settings which could override your options from application (they...

Thank you for bisecting the code and the logs! URF is a document format for AirPrint and ```cupsUrfSupported``` is PPD keyword for its IPP attribute equivalent - ```urf-supported``` - it...

Ok, we generate the cupsUrfSupported badly: From IPP response: ``` ATTR keyword urf-supported "CP1","MT1-2-8-9-10-11","PQ3-4-5","RS300-600","SRGB24","OB9","OFU0","W8-16","DEVW8-16","DEVRGB24-48","ADOBERGB24-48","DM3","IS1","V1.5","FN3" ``` and what we create: ``` *cupsUrfSupported: "CP1,MT1-2-8-9-10-11PQ3-4-5RS300-600SRGB24OB9OFU0W8-16DEVW8-16DEVRGB24-48ADOBERGB24-48DM3IS1V1.5FN3" ``` not enough commas :) ... I'm sorry...
