I am trying to printout some ASCII Text (using LPR,
script see below) to a IBM Proprinter compatible
dot-matrix printer, on a server running Linux.
Printing works fine, however 2 problems:
1. linefeed ("\n") doesn't work
2. escape sequences to print BOLD, ITALIC, UNDERLINE,
NARROW don't work
Any help is appreciated!!
Thanks!
