severity 1002642 grave thanks This is a new installation on bookworm. Establish queue: lpadmin -p testq -v tea4cuos:// -E -m raw Add to /etc/cups/tea4cups.conf: prehook_test : touch /tmp/TEA4CUPS-TEST Print: lp -d teatq test.txt Outcome: TEA4CUPS-TEST does not appear in /tmp and an error_log snippet as for the bug submitter is recorded. Conclusion: The package is non-functional without python3-requests as a dependency. Regards, Brian.
