On Wednesday's call there was some discussion of a proposal to add a new
or a parameter to Validate-Job to handle print by reference. It is not clear
to me that we
need such an operation.
Currently, I believe the function of Validate-Job is to validate the job
Printer capabilities. This should be independent of whether or not the
document will be
passed or printed by reference.
If one wants to test whether or not print-by reference is supported, then he
a Get-Operations request.
If the objective of this new operation is to test whether or not the given URI
i.e. if the Printer can get it, then I am concerned that we are testing a
variable. I could try the URI at one instant and because of server or network
not be able to get to the document. Furthermore, I could find the document and
back okay only to have the document owner move or delete it before the Print-URI
request was sent and operated upon by the Printer.
