Can you please do the following test:
First, remove your workaround using the command
lpadmin -p Hewlett-Packard-HP-LaserJet-4050-Series -R pdftops-renderer-default
The set CUPS debug logging as shown in "CUPS error_log" on https://wiki.ubuntu.com/DebuggingPrintingProblems, print one job and when you get the error page again, attach your error_log here.
After that, to be able to print, get back to your workaround via
lpadmin -p Hewlett-Packard-HP-LaserJet-4050-Series -o pdftops-renderer-default=pdftops
