Abstract
In a printer for printing on a recording medium using a transfer medium, a transfer medium capable of being repeatedly used at the same portion thereof (e.g., a multi-pass thermal transfer ribbon) is conveyed in the normal direction in performing the printing process by a recording means such as a thermal head etc. and the conveying amount of the transfer medium which is used for printing is measured at that time. The transfer medium is conveyed in the reverse direction by a given amount based on the result of the measurement and the reverse direction conveying ratio of the transfer medium to the used length of the transfer medium which is arbitrarily set by a transfer medium reverse direction conveying ratio setting means irrespective of the used amount of the transfer medium every time a unit of printing is completed. Thereafter the transfer medium is conveyed in the normal direction for printing. Repeating these processes, it is possible to use up the transfer medium so far as it is can be practically used for printing.
