Printing on both sides of the paper
I have a redhat 9.0 machine and I had configured Network Printer(LaserJet) using KDE. I wanted print documents on both sides of the paper. kprinter(0.0.1) doesnt provide an for 'Printing on both sides'. I have LPRng-3.8.19 and there is no "Duplex" option. Finally I tried with "a2ps". This is the command I tried.
$ a2ps -s2 --quiet --no-header -d foo.txt
This prints two pages on the single side. I want to print two pages on both the sides of the paper. The a2ps version is "GNU a2ps 4.13".
I was trying to use some GUI applications to print on both sides of the paper, but no application had that option. So atlast I wanted to try a command line tool. I wasted a few number of papers. So, please suggest some applications or give me some ideas which can allow me to print on both sides of the paper.
