Abstract: In one embodiment, a printer includes a device configured to form a semisolid toner film on a print substrate and a fixer configured to, without contacting the toner film, soften the toner film on the print substrate until polymers in the toner are mobile enough to allow polymer functional groups to bond with the print substrate.
