Abstract: A page (BASE PAGE) modification method in a printer subsystem of the partial page buffer composing type for generation of distinct copy groups (CG #1, CG #2, CG #3) or versions of a base page. A printer subsystem receives a packet containing a page of characters, coded overlays/elisions (OL #1, OL #2, S #1, S #2) and combining data from an external source. The packet is translated into a linked list of character placement representations for each of the doubly indexed coded characters within the page. Elisions (S #1, S #2) from the page are made by inhibiting the formation of a linked list segment for each character sequence within elision markers set out in the page. In contrast, coded character overlays are appended to the list as addenda. The list governs the placement of characters into a partial page buffer, whose contents are system accessible in row major order.

Abstract: RASTER PRINTER WITH SUFFICIENT PRINTING FLEXIBILITY A raster printer is provided with sufficient flexibility so that text data and image data of any size and orientation can be placed at any position on a page. Input data comprises a succession of coded character data long with control data which specifies information concerning font selection and the placement of the characters on the page. Control means is provided to process the input data, one character at a time, and generate for each of the characters, data relating to the position of the character on the page, the size of the character and the address in storage of the graphic pattern for the character. The data is utilized by pattern move control means to access the graphic pattern in the order the characters are to be printed and move the graphic data to a strip buffer means. Data is read out of the strip buffer to energize imaging apparatus to print a page corresponding to the graphic pattern of the input character data. Accumulator means are provided as a temporary storage for parts of the graphic pattern data and this data is logically ORed with later data so that a page of unlimited complexity can be printed.
