ABSTRACT:
A line printer which processes print data transmitted from a host computer and prints a document on a paper, comprising a character data processing portion that converts print data that are input into character codes, a buffer for storing character codes that are processed, a memory for storing fonts for the character codes, a bit map memory for storing character pattern data to be printed, a character pattern expansion portion that forms character patterns by calling, from the memory, fonts for said character codes and expands and stores the formed character patterns in the bit map memory, and a printing mechanism for printing the content of the bit map memory, wherein when a plurality of documents having a width narrower than one-half the width of the bit map memory are to be printed at one time on the printing paper according to a first aspect, the print data are transmitted having inserted therein the expansion position data that instruct the division of the bit map memory into a plurality of regions for the documents and, according to a second aspect, the print data are transmitted having inserted therein an address which instructs the division of buffer into a plurality of regions for the documents. Accordingly, the invention makes it possible to print a plurality of documents on one page without changing the data of the documents.
