You need the PCL key to Print PCL.These copiers use emulation and therefore are slower than true PCL and Postscript.It would be nice if Panasonic could use an external controller like an EFI product for true Postscript.
also set the dpi to 150 for black and white normally set at 600 i think! will spool and print even faster with the gdi driver which incorporates many types of uses
