1. A printing system comprising: (a) a raster storing means including a page memory for storing at least one page of information to be printed, each page being comprised of a plurality of lines of information including a beginning line, a plurality of intermediate lines and an ending line, each line having one or more successively addressed words each having a plurality of pixels, with a beginning word having the lowest address, with each successive word having a higher address, and with the last word having the highest address; (b) means, coupled to the page memory, for causing the readout of words stored in the page memory in either a first direction or a second direction, the first direction being from the first line successively thru the intermediate lines thru the last line with each line being read out in a direction from the lowest addressed word to the highest addressed word, the second direction being from the last line successively thru the intermediate lines thru the first line with each line being read out in a direction from the highest addressed word to the lowest addressed word and the significance of pixel positions of pixels from words read in the second direction being reversed from the significance of pixel positions of pixels from words read in the first direction; and (c) printing means for printing on first and second sides of a printing medium, coupled to the means causing the readout of words, for printing pages of information stored in the page memory on a printing medium having a top and bottom, with the printing of the first side of the printing medium being performed by printing the page of information read out from the page memory in one of the first and second directions while moving the printing medium from the top to the bottom thru a printing station and the printing of second side of the printing medium being performed by printing the page of information readout from the page memory in the other of the first and second directions while moving the printing medium from the bottom to the top.
7. A printing system in accordance with claim 1, further comprising: (a) a page memory for storing a plurality of pages of information in a format of encoded characters to be printed and a font storage memory for storing one or more fonts of selectable characters each having a plurality of characters, and each character is stored as a matrix of pixels which are addressable as words with each word having a plurality of pixels; (b) a raster forms storage memory for storing at least one form which may be selected with each form being stored as a matrix of pixels which are addressable in words with each word being comprised of a plurality of pixels and wherein: (c) the page memory has a first page memory for storing a full page of pixels of information to be printed and a second page memory for storing a full page of pixels of information to be printed; (d) the first page memory and the second page memory are alternately loaded with a page of information while a page of information stored in the other of the first page memory and the second page memory is being read out by the means for causing the readout and printed by the printing means; and (e) the means for causing the readout of words is coupled to the first page memory, the second page memory and the raster forms storage memory so as to permit readout of the first page memory, the second page memory and the raster forms storage memory in either the first or second directions.
