An arrangement for emulating printer responses to combinations of applications, control commands and printers stores bit maps of characters which may be produced by a variety of printers connected to the system. Bit maps corresponding to characters within a text string, indicated by a cursor position within a text file are retrieved in accordance with a printer selection, a character code and a table address. The table address is retrieved from memory in response to a selected application profile and one or more selected commands. The printer response is produced in a window of the display as a sequential series of sub-windows corresponding to characters of the text string; each sub-window having a width corresponding to the width of each character image. The display also includes a plurality of menus for facilitating operator selection of a combination of application profiles, commands and printers to be emulated.
