Abstract: A personal computer (A) generates print data which is conveyed from its printer output port (16) along a printer cable (18) to an associated printer (B). A remote telecommunications unit (C) is connected with the printer cable to receive the print data at an input port (20), pass the data from a printer output port (22) to the printer, and pass print data from a telecommunications port (52) to a telephone communications line (54). The print data is intercepted and a copy is stored in a disk memory (40). A dial-up means (42) dials the phone number of a central processing computer modem (60) to establish a telecommunications link. Thereafter, a telecommunications controller (48) conveys the print data from the disk memory to the modem (60). A form identification means (62, 62') identifies to which of a plurality of preselected forms each page of print data corresponds. From the generated form identification, a corresponding map (66, 66') is selected.
