Abstract
Abstract Here is disclosed a printer capable of printing character information in the same printing format irrespective of the direction in which sheets of paper (30) for printing are loaded. Such a printer comprises a cassette (20) which can receive the printing sheets (30) either in a longitudinal direction or in a traverse direction, a detecting portion (18) for detecting direction of the printing sheets (30) loaded in the cassette (20), a format setting key (6a) for setting a format including feeding manner of the printing sheets (30), alignment direction of characters and the like, and a control portion (10). The control portion (10) determines whether or not the actual direction of the printing sheets (30) detected by the detecting portion (18) corresponds to the direction having been set by the setting key (6a). If they do not correspond to each other, the control portion (10) controls the printer such that printing data read out of a document buffer (12) where character information is stored are rotated by 90°, written in a printing buffer (17) and then supplied from the printing buffer (17) to a laser printer (4).
