ABSTRACT A printer includes a print mechanism defining a print region and a removable ink ribbon cartridge. The cartridge includes a body and two arms which are pivotally attached to the body at one end and are spaced apart at the other end. An ink ribbon in the cartridge extends from the body, along one of the arms, across the gap between the ends of the arms and along the other arm back into the body. When the cartridge is in position in the printer the portion of the ribbon extending across the gap is located in the print region and a feed system feeds the ribbon out of the cartridge, through the print region and back into the cartridge. The printer includes an arm moving mechanism for moving the arms about their pivots on the body of the cartridge so that the portion of the ribbon in the print region can be moved laterally. One of the arms is formed with a first indicator which cooperates with a sensing system on the printer. The sensing system detects the position of the indicator and uses this information to indicate the lateral position of the ribbon in the print region. The sensing system can also determine whether the cartridge is installed correctly in the printer. A second indicator is located on the arm in a position which corresponds to the type of ribbon in the cartridge and the sensing system can detect the position of this second indicator and uses this information to indicate the type of ribbon in the cartridge. The invention also includes a removable ink ribbon cartridge which can he used in a printer as above.
