1) What if I've hopped networks since then and the print job that was
que'd was on a printer that was only visible on the original network?
Answering my own questions: test the ipaddress and continue to wait if
its not available

2) What if I've hopped networks and the old network and the new
network have a printer at the same 192.168.x.x address but are
physically different printers?
I have no idea how to make sure you aren't printing to the wrong
printer that is scoped with a local network address. Do we have any
technical mechanism to prevent this from happening for que'd jobs that
automatically try to start on re-login for personal computing that are
anticipated to hop networks ?
