Network printer: remote jobs hang, print if requeued locally

Summary
-------
Two computers ('office', 'manticore') and an Ethernet-attached
printer (Brother MFC420CN) are connected to the same LAN.
CUPS 1.2.7 is running under openSuSE 10.2 on 'manticore'.
Printing from 'manticore' apps (e.g. gedit, inkscape) works as
expected (print stream is written to spool file, job is queued, job
prints, spool file is deleted).
Remote printing from 'office' apps fails. The print stream is
written to a spool file, the job is queued, the job starts printing,
the printer LCD panel acknowledges that data is being received...
and then nothing further happens.
If the spool file is manually requeued by issuing (e.g.)
lp -d mfc420cn /var/spool/cups/d00082-001
the job prints without getting hung.
Can anyone help me figure out whether this is a Bug, a Configuration
Error, or (an old IBM favorite) a Probable User Error?
Any clues, hints, or suggestions will be appreciated.
