    • A printing method and apparatus capable of continuously printing information on a plurality of labels (109) at a correct position without reducing throughput. Upon printing an image on labels (109) stuck on a roll-shaped continuous sheet (108) with a predetermined interval while reciprocally scanning a printhead (100), the printing apparatus receives a raster image command from a host and bitmaps raster data to a data buffer having a capacity capable of storing data for a single scan-printing by the printhead (100), discriminates whether or not raster data to be printed on a plurality of continuous labels can be bitmapped to the data buffer, bitmaps null data for rasters corresponding to a predetermined interval between the labels to the data buffer in accordance with the discrimination result, further discriminates whether or not data for a single scan-printing by the printhead (100) is bitmapped to the data buffer, and prints by scanning the printhead (100) in accordance with the discrimination result.

    • The appts includes a second outlet guide member (92) is turned around a pivot (92a) in the direction of an arrow G, i.e., moved from a position of solid lines to a position of two-dot chain lines. A rear end portion (92b) of the second outlet guide member (92) presses down a front end portion (80c) of a guide member (80) to cause the guide member (80) to be turned around a central shaft (80d) in the direction of an arrow H. A path extending in the direction of an arrow C is closed, while a path extending in the direction of an arrow F is opened. The roll paper (72) is transferred in the paper feed direction. When the roll paper unit (200) is drawn out, the second outlet guide member (92) and the guide member (80) are turned in the directions opposite to those mentioned above. Consequently, the path extending in the direction of the arrow F is closed, while the path extending in the direction of the arrow C is opened. the roll paper (72) is transferred in the paper discharge direction.
