Hi All. I write small script: #!/bin/bash echo -e "...PJL commands..." | cat > /dev/lp0 cat /dev/lp0 When I try it run I get nothing. When I run this script two time (one after the other) I get informations. I need write to & read from /dev/lp0 in one & the same script. How do this do? Any help appreciated. Thanks.
