Portable printer and method
There is disclosed a portable printer operable in either a strip mode or a peel mode. In the peel mode, a pressure roll cooperates with a carrier web and the platen roll to strip labels from the web. A battery-powered electric motor advances a printable web through the printer. In order to reduce drag on the motor in the strip mode, the pressure roll is held in out of pressure contact with the platen roll.
1. A printer operable in either a strip mode wherein a printable strip is dispensed or in a peel mode wherein labels on a carrier web are peeled and dispensed from a carrier web, the printer comprising:
a print head,
a driven platen roll cooperable with the print head,
a delaminator disposed downstream of the print head,
a pressure roll disposed downstream of the delaminator,
a holder, wherein the holder mounts the pressure roll in a strip mode position out of pressure cooperation with the carrier web and the platen roll in the strip mode and a peel mode position in pressure cooperation with the carrier web and the platen roll in the peel mode, and
an actuator selectively positionable out of actuating relationship with the holder in the strip mode and in actuating relationship with the holder in the peel mode, and the actuator being operative to locate the pressure roll in the peel mode position.
2. A printer as defined in claim 1 , including at least one spring to urge the holder to the strip mode position.
3. A printer as defined in claim 1 , including
at least one spring acting on the holder to urge the pressure roll to the strip mode position, wherein the actuator includes at least one stop settable in either a first position or in a second position, the stop(s) being effective in the first position to act on the holder to overcome the force(s) of the spring(s) and to urge the pressure roll into the peel mode position and the stop(s) being ineffective in the second position to act on the holder either to overcome the force(s) of the spring(s) or to urge the pressure roll into the peel mode position.
4. A printer as defined in claim 1 , including a tear bar on the holder.
5. A printer as defined in claim 1 , including at least one spring that helps resiliently urge the pressure roll in pressure relationship with the platen roll in the peel mode.
6. A printer as defined in claim 1 , including a housing having a first housing section and a second housing section relatively movable between open and closed positions, wherein the platen roll, the delaminator, the pressure roll, and the holder are on the first housing section and the actuator is on the second housing section.
