The function set-printer-options
allows some printer options for the current job to be set programmatically. Note that the user can change the various printer options in the dialog displayed by print-dialog.
The printer argument should be a printer object returned by current-printer or print-dialog. This printer should then be passed to with-print-job to print using the options specified.
The keyword arguments control which options are set. If a keyword is not passed then the option remains unchanged.
