Wouldn't the test where lpd sent output to a file and the later the file was manually cat-ed to /dev/lp0 rule out these problems? The system does seem to have interrupt problems occasionally, although not related to printing. When burning a cd by reading the iso off /dev/cdroms/cdrom0 (ATPI) to /dev/cdroms/cdrom1 (scsiII, second controller) I seem to receive reduced data rates on the modem (inbound), external serial. IIRC at least. I just figured it was ide/atpi/ designed inability of cdrom to seek related problem.
