@sander.loones Hi Sander, thanks for pointing out the error in the documentation! Indeed, “job-start-sheet” is the right value for the “org.savapage-job-sheets” IPP keyword (Manual is adapted).
The Job Ticket Operator (not the Job Ticket Creator) selects the input tray for the job sheet at the redirect printer. See Job Ticket Print. An extra option (marked with a “label” icon) appears in case a job-sheet is selected (I still have to complete the manual to reflect this case.).
Yes, you can name a tray anything you want, as long as you assign it a paper size. See the Media Sources section in the User Manual. Also note that at the bottom of the section it reads:
" When the printer is member of at least one Job Ticket Printer Group, and can therefore act as redirect printer, a media-source select menu for Job Sheets is shown. Multiple media-sources with assigned media-size can be selected. When this printer is selected as redirect printer, the first Jobs Sheets media-source that matches the requested job-sheet media size will be selected as default."
