ABSTRACT:
A printer is selectively supplied with ink by moving a print head to an end position and bringing an ink supply element into contact with an ink absorbing material in the print head. At that time ink can be supplied to the ink absorbing material in the print head either by pressing a flexible bag containing an ink supply or by capillary action from another ink absorbing material that is impregnated with ink and that has a capillary force smaller than a capillary force of the ink absorbing material of the print head. The ink supply device is located at one end of a platen for the printer and can be rotated out of position until the print head moves to the end of the platen, at which time the ink supply device is rotated into contact with the print head. An arrangement of rotating a discoid cam can be used to apply a pressing force to the flexible bag, which includes a self-sealing valve, so that ink flows to the ink absorbing material in the print head.
