Most application programs let you specify the type of printer you use
so that the program can take full advantage of the printer’s features.
Many of these programs provide an installation or setup section that
presents a list of printers.
Choosing from a menu
Because Epson printers share a great many commands, you can use
an application program even if it does not list your printer on its
printer selection menu. If your printer is not listed, choose from the
following list (the printers are listed in tire order of preference):
LQ-850/1050
LQ-510/550/1010
LQ-200
LQ-500
LQ-86O+/lOfio+
LQ-2550
LQ-2500
