Basically that's it what I would suggest to keep oneself
out of getting trapped within inexplicable complications.

Of course that workaround is primarily meant for what are
"in practice single user" environments i.e. where a printer
is usually used only by a single user at a time (which includes
e.g. usual office use cases where users on client workstations
use a particular printer only every now and then so in practice
possibly conflicting printing tasks at the same time happen rarely).
