Specify the Printer Language to be used for printing.
Format
filetype=Printer Language name
Or
fil=Printer Language name
Value and behavior
Substitute the three-letter abbreviation of the printer language name for "Printer Language name". To switch to RTIFF, specify "RTF". The default values of the RPGL Menu are applied.
Explanation
The Printer Language selected using the control panel is used for printing, unless this printing option is specified. If RTIFF is not selected, output files may not be printed normally. If "Auto" is selected in "Printer Language" on the "System" tab under "Printer Features", the machine automatically switches its printer language to RTIFF when it receives a correct TIFF file.
