2. I am using following GS command to convert PS to PCL
gs -sDEVICE=pcl3 -r600 -sColorModel=CMY -dNOPAUSE -dBATCH -dSAFER -dNOINTERPOLATE -sOutputFile=/home/lfs/psTopclfile /home/lfs/imgtopsfile -c quit
gs -sDEVICE=pxlcolor -dNOPAUSE -dBATCH -dSAFER -dNOINTERPOLATE -sOutputFile=/home/lfs/psTopclfile /home/lfs/imgtopsfile -c quit
gs -sDEVICE=pxlmono -dNOPAUSE -dBATCH -dSAFER -dNOINTERPOLATE -sOutputFile=/home/lfs/psTopclfile /home/lfs/imgtopsfile -c quit
3. when I tried to start it with -dDuplex option, gs came out with error code 255.
4. Issue is : in all above three cases output PCL file is simplex.
I do not know whether it is problem of input PS file, but
PostScript printer is printing Duplex.
Please give response.
