Printing line data on AFP printers

All AFP printers are page printers. Page printers differ from line printers in that a page printer receives an entire page of data before it prints any data, whereas a line printer receives one line of data at a time and prints each line as it is received.

PSF can process line data so that AFP page printers can print it; therefore, a job that is prepared for printing on a line printer can be printed on a page printer with little or no change to the application. You can enhance line data by using electronic forms (overlays), typographic fonts, and other advanced-printing functions. For more information about line data, see Line data. Also, see Printing on an AFP printer.
