Metafile Spooling - Kyocera KM-4230 Instruction Handbook Manual

2. Printer Driver for WindowsNT
I Metafile Spooling:
Specifies the format in which store printing information on your disk while a print job is waiting to be printed. Generally, EMF(metafile)
format frees up your program faster because it is smaller and doesn't depend on what kind of printing device you have. RAW format is
specific to the printing device, so extra time may be required to convert the printing information, and your program would not be available
for working on other tasks.
If you have problems printing using EMF, try RAW.
