The price was attractive, and it seems to be a good printer. However, there is either the choice of a an open-source driver for a different printer model, one which doesn't support the 1200x600DPI mode, or a closed-source driver which comes on the included CDROM. <p>I'm going to try to reverse engineer the new format, which is called &quot;SPL II&quot; in the GUI and &quot;QPDL&quot; in the generated file (<tt>@PJL ENTER LANGUAGE = QPDL</tt>). My approach is to print a postscript file using the binary driver, saving the result to a local file. At no time do I plan to disassemble the binary software provided by Samsung.
