Just create the tabs as a 9*11 job in Word and send it to print on the tabs loaded as 9*11 cardstock and be done with it.
I am not familiar with that printer, however, I searched the Knowledge-base and found some solutions that may help answer your questions:
Can I print non collated tabs on igen? Not inserting into job. Just printing 20 copies of #1 on 20 sheets of same position tab stock. Sequence in stock setting won't let me put in a 1 as value.
