whole pages, and output is
printed on half the page.

This is a known bug in Ghostscript (until GNU Ghostscript version 7.xx) when the base color space of the document is indexed RGB
color space and it is converted through CIE color space. Because Postscript uses CIE color space for Color Matching System, you
should upgrade Ghostscript on your system to at least GNU Ghostscript version 8.xx or later. You can find recent Ghostscript versions
at www.ghostscript.com.
It is a known problem that occurs when a color machine is used on version 8.51 or earlier of Ghostscript, 64-bit Linux OS, and has been
reported to bugs.ghostscript.com as Ghostscript Bug 688252.The problem is solved in AFPL Ghostscript v. 8.52 or above. Download
the latest version of AFPL Ghostscript from http://sourceforge.net/projects/ghostscript/ and install it to solve this problem.
Avoid changing print job parameters (via LPR GUI, for example) while a print job is in progress. Known versions of CUPS server break
the print job whenever print options are changed and then try to restart the job from the beginning. Since Unified Linux Driver locks
the mfp port while printing, the abrupt termination of the driver keeps the port locked and unavailable for subsequent print jobs. If
this situation occurs, try to release the mfp port by selecting Release port in Port configuration window.
