this is an addition to the reply you already got back from Randy about HTTP
The Create-Job operation, if successful, always returns a job URI. You
will use that URI to post any further documents (Send-Document) or
print-by-reference URIs (Send-URI) that belong to that job, even if you do
it in a new HTTP connection. In effect you will probably have to make it in
a new connection as the job URI is different from the Printer URI, that you
use for the Create-Job.
