you don't need any printer description (I use these solutions in my applications with any dot matrix printer compatible IBM and EPSON):

if you print your reports from .frx reports :

repo form myrep to file myrep.txt ascii

on erro retr
copy file myrep.txt to lpt1

if you want to print your repots with code:

way 1:

use ??? command . it skip windows printer

way 2:

set prin to myrep.txt
?"kldkfld"
?"mvkcvcxk"
ejec

set prin to

on erro retr

copy file myrep.txt to lpt1
