WNetOpenEnum lets you enumerate over the connected network resources
you could try dwScope RESOURCE_CONNECTED and dwType RESOURCETYPE_PRINT
and see if the one you are looking for comes back as "connected"
no idea if this is the same as being "available" in the
sense of your thread crasher though.

Subject: [DUG]: Detecting printer availability
OK, Myles' comments make sense and Seagate is now "struggling" with the
issue. In the interum, is there a way for us to check that the printer /
network connection is available before we execute the report??
