I have a 3 page dot

I want to have the first page from Tray2 ltrhead

Page2 on the back of the first pg

Page3 from Tray2 ltrhead.

After merging to a new doc, I can get the first record to print right, but
each doc after prints the 2nd page on fresh letterhead rather than the back
of the first pg and the 3rd pg on the back of the 2nd pg.

Before I'm fix it, what is the best practice, insert sections, page breaks
or ? and then how to do pg setup.

FYI, I've solved one problem w/my HP printers, regardless of model, I use
the same driver so that I don't loose my page setup when I switch printers,
where I keep specific pre-printed letterhead always in Tray2.

TIA
