Claims
- 1. Apparatus for printing on webs of record members, the printing apparatus comprising: a print head, a platen cooperable with the print head, a pair of hubs receivable in rolls of record members of different widths, the hubs being on opposite sides of a centerline of the apparatus, a movable rack for each hub, a rotatable gear disposed generally along the centerline and meshing with both racks, and wherein the hubs are movable in unison with respect to the centerline as the racks move and the gear rotates to accommodate record member rolls of different widths.
- 2. Apparatus as defined in claim 1, wherein the hubs are rotatably mounted.
- 3. Apparatus as defined in claim 1, including a pair of uprights, each upright being connected to one of the racks, wherein one of the hubs is mounted to each upright, and wherein the hubs are rotatably mounted with respect to the uprights.
- 4. Apparatus for printing on webs of record members, the printing apparatus comprising: a print head, a platen cooperable with the print head, a pair of hubs receivable in rolls of record members of different widths, the hubs being on opposite sides of a centerline of the apparatus, a pair of uprights for mounting the hubs, a movable rack for each hub, one of the racks being connected to one of the uprights and the other of the racks being connected to the other of the uprights, a rotatable gear disposed generally along the centerline and meshing with both racks, and wherein the hubs are movable in unison with respect to the centerline as the racks move and the gear rotates to accommodate record member rolls of different widths.
- 5. Apparatus for printing on webs of record members, the printing apparatus comprising: a print head, a platen cooperable with the print head, a pair of hubs receivable in rolls of record members of different widths, the hubs being on opposite sides of a centerline of the apparatus, a movable rack for each hub, a rotatable gear disposed generally along the centerline and meshing with both racks, wherein the hubs are movable equal distances to selected positions with respect to the centerline as the racks move and the gear rotates to accommodate record member rolls of different widths, and wherein the hubs are releasably held in their selected positions.
- 6. Apparatus as defined in claim 5, wherein the hubs are rotatably mounted.
- 7. Apparatus as defined in claim 4, wherein the hubs are rotatably mounted.
- 8. Apparatus for printing on webs of record members, the printing apparatus comprising: a housing having a cover movable between open and closed positions, a print head, a platen cooperable with the print head, wherein the platen includes a platen roll, an electric motor for driving the platen roll, wherein a roll of record members is loadable onto the hubs when the cover is open, a pair of hubs receivable in rolls of record members of different widths, the hubs being on opposite sides of a centerline of the apparatus, a movable rack for each hub, a rotatable gear disposed generally along the centerline and meshing with both racks, and wherein the hubs are movable in unison with respect to the centerline as the racks move and the gear rotates to accommodate record member rolls of different widths.
- 9. Apparatus for printing on webs of record members, the printing apparatus comprising: a housing, the housing having a cover movable between open and closed positions, a scanner mounted to the cover, a print head, a motor-driven platen roll cooperable with the print heads, a pair of hubs receivable in rolls of record members of different widths, the hubs being on opposite sides of a centerline of the apparatus, the cover being operable to enable record member rolls to be mounted on the hubs, wherein the record members can comprise labels on a carrier web, a discharge chute for the carrier web, a movable rack for each hub, a rotatable gear disposed generally along the centerline and meshing with both racks, and wherein the hubs are movable in unison with respect to the centerline as the racks move and the gear rotates to accommodate record member rolls of different widths.
