What probably won't work is the offset in the output, i.e. cover letter 1 + questionnaire 1 "left", cover letter 2 + questionnaire 2 "right", cover letter 3 + questionnaire 3 "left", etc.?

There are no hard-and-fast rules for this, but if you are the only system sending jobs then it should print jobs in the order they are submitted.

Actually, no.  "finishings" is both a Job and Document Template attribute, so a Printer that supports multiple-document jobs (look for multiple-document-jobs-supported=true in the get-printer-attributes.test output) should support finishings in the Send-Document request (in the document-attributes-tag group).

The old "job-finishings" attribute (obsolete, from the old PWG 5100.7-2003 Job Extensions spec) was defined to explicitly apply to the whole job, regardless of the value of multiple-document-handling, but we made it obsolete because that just has too many interoperability issues and side-effects.

"finishings" as a Job Template attribute applies to a Set - so either all of the Documents together or each Document individually depending on "multiple-document-handling".

"finishings" as a Document Template attribute applies to just that Document. It is basically an override for the whole document (vs. specific Input Pages/Documents in the case of the "overrides" Job Template attribute) but relies on the Printer supporting multiple-document Jobs.

> Incidentally, during my experiments I noticed that "Validate-Job" cannot be used in combination with "Create-Job" and "Send-Document". I now always send a "Cancel-Job" after it so that the printer does not print a page. Unfortunately, the job counter then counts up :-)

Validate-Job should not be creating a Job or interacting with any pending Jobs.  It is there solely for validating a Job Ticket, not for actually doing any work.
