Most likely, you are using a bad font.
Our office uses ColorQube 9201. Printing a 108 page .pdf two-sided from Foxit. The output is fine through page 55. When it hits page 56, this message prints:
OFFENDING COMMAND: setcachedevice
and the print job stops.
Page 56 begins a table of 10 columns of numbers and it continues through page 72.
Any ideas why this happens?
