CUPS: hold and release jobs using IPP hold-new-job or cupsdisable --hold and cupsenable --release

Hello everyone ^^

I am working on a project where I am using CUPS as a printer server.
I want to hold all new printer jobs, check the cartridge levels of my printer and one by one release jobs for printing. I want to enable the hold-new-jobs attribute on a specific printer in CUPS.
After this, I have to find out how to get all jobs that are on-hold and release one (by job ID, or so using FIFO) For completeness: If cartridges are below a threshold, the jobs are held until cartridges are reset and a button is pressed. (The implementation can be done also through cupsdisable --hold and cupsenable --release )

There is no example of IPPRequests for pycups. Note that I am searching for a solution using pycups in Python or <cups cups.h=""> in C.

If you need any additional information just mention it.
Thank you in advance.
