The printing system is intended to put ink or toner on paper. If it does not do that it has failed. Can we agree on that? Does it matter for the primary purpose of printing whether a PDF produced during the process is searchable or not?
Note that the cups-pdf driver is an exception here. It is meant to be used out of applications without "Save as PDF", "Export to PDF", or similar functionality. So "printing" a file to a cups-pdf "printer" is not necessarily done with the intention of getting the file onto paper. And for a PDF file it makes sense to have it searchable.
Problem is most probably in cups-pdf upstream, but it can be that the application is the culprit sending non-searchable PDF to CUPS (then CUPS/cups-filters cannot turn the PDF back searchable).
You need to check the PDF which is sent to CUPS, following Capturing print job data on https://wiki.ubuntu.com/DebuggingPrintingProblems and tell us from which application you have printed to cups-pdf. Till
