1. A printer for use in peeling a label from a backing, the label when on the backing forming a media, said printer comprising:
- a housing;
a printhead associated with said housing;
a platen roller associated with said housing;
peel means proximate to said platen roller for bending the backing therearound; and
separator means proximate to said peel means for separating the backing from the labels, wherein the media passes over said peel means, the backing passes between said peel means and said separator means and the labels pass over said separator means, and the media is pushed through the printer solely by said platen roller such that zero tension is applied to the backing.

Abstract
A novel passive peel system for a printer is provided for peeling labels off of a backing. Labels secured to a backing is defined as media. The printer has a printhead for printing indicia on the labels and a platen roller. A first embodiment of the passive peel system includes a peel tear bar proximate to the platen roller for bending the backing therearound and a separator bar proximate to the peel tear bar for separating the backing from the labels after the labels have been printed on by the printhead. The media passes over the peel tear bar, the backing passes between the peel tear bar and the separator bar, and the labels pass over the separator bar. The labels can be peeled with low tension or with zero tension on the backing. A second embodiment of the passive peel system includes a peel tear bar and an anti-buckle bar mounted proximate to the peel tear bar for preventing buckling of the media as the media passes over the peel tear bar. The media passes between the peel tear bar and said anti-buckle bar. The labels can be peeled with low tension on the backing. The third embodiment of the passive peel system is the same as the first embodiment with the addition of the anti-buckle bar of the second embodiment. The labels can be peeled with low tension or with zero tension on the backing.

7. A printer for use in peeling a label from a backing, the label when on the backing forming a media, said printer comprising:
- a housing;
a printhead associated with said housing;
a platen roller associated with said housing;
peel means proximate to said platen roller for bending the backing therearound;
separator means proximate to said peel means for separating the backing from the labels;
tension applying means for applying tension to the backing and wherein the media is pushed through the printer by said platen roller and the backing is pulled by said tension applying means such that tension is applied to the backing, wherein the media passes over said peel means, the backing passes between said peel means and said separator means and the labels pass over said separator means, and said peel means includes a corner around which the backing is bent to separate the label from the backing. - View Dependent Claims (8, 9, 10, 11)

12. A method of dispensing a label from a printer comprising the steps of:
-
providing a media, said media comprising a backing having at least one label releasably secured thereto;
providing a printer comprising a housing, a printhead associated with said housing, a platen roller associated with said housing, peel means proximate to said platen roller for bending the backing therearound, said peel means including a corner around which the backing is bent to separate the label from the backing, and separator means proximate to said peel means for separating the backing from the labels;
passing said media over said peel means;
passing said backing between said peel means and said separator means;
passing said label over said separator means; and
applying tension to the backing and wherein the media is pushed through the printer by said platen roller and said backing is pulled under tension. - View Dependent Claims (13)

14. A method of dispensing a label from a printer comprising the steps of:
-
providing a media, said media comprising a backing having at least one label releasably secured thereto;
providing a printer comprising a housing, a printhead associated with said housing, a platen roller associated with said housing, peel means proximate to said platen roller for bending the backing therearound, and separator means proximate to said peel means for separating the backing from the labels after;
passing said media over said peel means;
passing said backing between said peel means and said separator means; and
passing said label over said separator means, wherein the media is pushed through the printer solely by said platen roller such that zero tension is applied to the backing and such that said separator means causes said label to separate from said backing. - View Dependent Claims (15)

16. A printer for use in peeling a label from a backing, the label when on the backing forming a media, said printer comprising:
- a housing;
a printhead associated with said housing;
a platen roller associated with said housing;
peel means proximate to said platen roller for bending the backing therearound after the media to separate the label from the backing, said peel means including a corner which separates the label from the backing;
anti-buckle means proximate to said peel means for preventing buckling of the media as the media passes over said peel means, wherein the media passes between said peel means and said anti-buckle means; and
tension applying means for applying tension to the backing and wherein the media is pushed through the printer by said platen roller and the backing is pulled by said tension applying means such that tension is applied to the backing. - View Dependent Claims (17, 18)

19. A method of dispensing a label from a printer comprising the steps of:
-
providing a media, said media comprising a backing having at least one label thereon;
providing a printer comprising a housing, a printhead associated with said housing, a platen roller associated with said housing, peel means proximate to said platen roller for bending the backing therearound, said peel means including a corner around which the backing is bent to separate the label from the backing, and anti-buckle means proximate to said peel means for preventing said media from buckling as said media passes between said peel means and said anti-buckle means;
passing said media between said peel means and said anti-buckle means; and
applying tension to said backing to cause said backing to bend around said peel means and to separate said label from said backing.
