Q2. Can I change the printing conditions of a job after it has already started printing?

A2. Yes.

While the job is being printed, press Stop to pause the printing. [Temporary Stop] is displayed. 

Press [Temporary Stop], and then press [Paper Setting]. The changeable items are displayed. Change the printing conditions and resume the job.

However, if [UTILITY] screen - [User Setting] or [Administrator Setting] - [Common Setting] - [Job Stop] is selected in [Stop Button Function], pressing Stop will delete the job. The printing conditions cannot be changed and the job cannot be resumed.
