Similar error messages appeared in /var/log/messages today. I've included all 
of the ptal-related messages generated during the session.

These startup messages would have been logged at boot. I start ptal-printd 
and ptal-mlcd from /etc/rc.d/rc.local .

dev=<par:0>, pid=786, errno=111         ptal-mlcd successfully initialized.
Jun 16 09:22:12 tumbleweed ptal-printd: ptal-printd(mlc:par:0) successfully 
initialized.


These error messages appear to have been logged shortly after boot. I don't 
think the printer was in active use at the time.
