Before downgrading, could you follow the instructions of the section "error_log" on https://wiki.ubuntu.com/DebuggingPrintingProblems and provide us the error_log of the time between boot and the first job, when CUPS is hogging the CPU? Thanks.

Finally, I checked resource usage with <top> and the culprit seems to be cupsd. Here is an output line from a few minutes after boot: 30900 root 20 0 305452 287396 5768 S 5,3 9,3 0:41.34 cupsd Then after an hour and a half (with nothing printed): 30900 root 20 0 2565692 2,125g 2240 R 79,0 71,9 93:01.45 cupsd So %CPU grows 5,3 -> 79,0 and %MEM, 9,3 -> 71,9. Not good. A user on a local forum asked whether printing anything helped, and, certainly, it did. After I did (print something), cupsd was happy with less than 1% of CPU and MEM. So if I print something after every boot, the problem does go away. But that is not really a solution, is it? Running Lubuntu 16.04.6 LTS (32-bit). cups version is 2.1.3-4ubuntu0.9.
