This doesn't seem to be lp- or parport-related. What else was the
machine doing at the time?

Running the oops thru ksymoops would be helpful also.
See linux/REPORTING-BUGS file.

This oops occurred at the moment of processing/handling a print job. The
print jobs are processed via a Samba printer share. The system is also
constantly running a MySQL database that is accessed via Apache+PHP.
So, the system is running MySQL, Samba, Apache, PHP, sendmail, lpd, and
various other things standard on an updated RedHat 7.0 system (I'm
upgrading kernels via tarball).
