Abstract: In an automatic editing device for an English letter, text data of the English letter is input by operating character keys and a space key, and an automatic edit key is then operated. The input text data is displayed at a left end portion of a display, and the layouts of four typical letter formats identified as numerals 1-4 are also displayed at a central portion of the display. In this condition, when one of numeral 1-4 keys is operated, a letter format flag corresponding to the numeral is set to select a desired one of the four letter formats. Then, the input text data is automatically edited to the selected letter format. The edited text data is stored into a work memory, and the layout of the stored text data is displayed at a right end portion of the display. Thus, when an operator merely inputs the text data of the English letter, the automatic editing device operates to automatically edit the input text data to a desired letter format.

Abstract: A printer having a printing unit for printing on a sheet and a sheet feeding control section for controlling continuous or cut sheet feeding is disclosed. The sheet feeding control section performs sheet feeding of a predetermined amount after the data corresponding to one page has been printed by the printing unit. The sheet detecting section detects whether or not the printing sheet exists in the vicinity of the printing unit. If no printing sheet is det4ected in the vicinity of the printing unit, the printing control section determines that no continuous-page sheet feeder has been mounted. On the other hand, if the printing sheet is detected, the printing control section determines that the continuous-page sheet feeder has been mounted. If it is found that no continuous-page sheet feeder is mounted, the printing operation is stopped temporarily. If it is found that the continuous-page sheet feeder has been mounted, the printing operation is continued.
