Hi! I've been using the ljet4 driver with gnu ghostscript for four years now. When I upgraded my linux from FC3 to FC6 I found out that my Duplex jobs were coming out one sided.
I downloaded, locally compiled and installed on the same FC6 machine two versions of GNU Ghostscript, 7.07 and 8.55. The PCL produced by ljet4 on 7.07 prints on both sides of the paper but the one produced by ljet4 on 8.55 comes out single-sided. These are the commands used to generate & print a test file: /path/to/gs -dNOPAUSE -sDEVICE=ljet4 -sOutputFile=tmp.pcl -q -r600 -dBATCH newfile1.ps echo "@PJL SET DUPLEX=ON" > /tmp/prefix cat /tmp/prefix tmp.pcl > /dev/tcp/my.hplj2200nd.port/9100 Attached files: newfile1.ps Test postscript file newfile1-707.pcl Ghostscript 7.07 ljet4 output file newfile1-855.pcl Ghostscript 8.55 ljet4 output file newfile1.tex Latex source file Best regards, Pablo Funes -- Pablo Funes, PhD Research Director Icosystem Corporation 10 Fawcett St. Cambridge MA 02138 USA
