"There are no printers available to print 2x7" message when printing rolls in SendPro Online or PitneyShip
If there is no supported printer installed for roll printing, one will need to be installed. See Installing the Brother QL-800 printer.
If there is a compatible SendPro Online or PitneyShip roll printer installed, there may be an issue detecting your printer list. See No printer selection window when printing stamps.
