I'm adapting a working linux program to cygwin. The process has been
relatively painless except for this issue which has delayed me way past
deadline.
I need to output text and printer codes (which may include \000) from a
perl program to a printer which may be on a parallel port or a USB port.
In the past I have done this on linux using something like the following.
system(qq/echo -en "$data_str" | lpr -oraw/);
...or whatever
That does not work in cygwin. It would work. But on cygwin echo behaves
differently in a perl system() command from the way it works from the
bash command line.
Why would want use echo for this? Just use a piped open directly to lpr:
open(FH, '| lpr -oraw');
print(FH, $data_str);
close(FH);
(Error handling left as an exercise to the reader...)
