摘要： 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.
