Hello JimP and macropod,
There is a problem!!
I got as far as printing 124 and 37 of a 160 page booklet, printing front-side first then I intended to print the other side by re-inserting the pages.
I had a paper jam and having cleared it, I have no idea how to continue from where it jammed.
There is nothing in the "waiting to print" and I can find no way to choose to print from the pages that have already been `printed.

Any idea how to continue? or is this wasted effort and paper?

Colin.
