If you print USPS First Class mail via Stamps.com, there is now a change in layout.
Teapplix use to print this on 8x11 paper 2 per label. Now we follow whatever you configured for your default PDF label size. This include 8x11 2 per page, or 4x6 shipping labels.
USPS Priority Mail and Express Mail international will continue to be printed on 8x11 paper.
