ABSTRACT:
A sheet-feeding mechanism of a printer conveys a recording sheet nipped between a first sheet-feeding roller and a first pressing roller towards a thermal head. At the start of a printing operation, a second pressing roller is disposed distant from a second sheet-feeding roller. When a front end of the recording sheet being printed is conveyed to a space between the second sheet-feeding roller and the second pressing roller disposed distant from each other, the second pressing roller gradually comes into press-contact with the recording sheet such that the recording sheet being printed is conveyed downstream by at least a second sheet-feeding unit. The first pressing roller is gradually shifted away from the recording sheet before a rear end of the recording sheet being printed is released from the nip between the first sheet-feeding roller and the first pressing roller.
