It is not generally possible in current releases of CUPS, as there
is no corresponding IPP operation for it.

That said, CUPS 1.4 includes a new CUPS-Get-Document operation that
could be used to implement a "copy job" function - you'd basically
need to create a new job using the options from the original, and
then copy the documents from the original job to the new one.
