Epson to Fax Conversion Utility (epstog3)
November 2009 414
The epstog3 utility displays help information on converting graphics
files to fax image files, on the command line.
Note:
Fonts must be located in the current directory for all platforms
except those platforms that use MS-DOS executables
(Windows® NT, Windows® 2000). For these cases, the fonts
must be located either in the font subdirectory of the directory
named by the FMAIL environment variable, if it is set, or in the
boston\bfv.api\fonts directory.
For example:
epstog3 -icap001.epc
converts a graphics file named cap001.epc to a Group 3 fax image
file.
If the output filename is not specified, it is automatically created
using the input filename and given an extension of .3XX.
If the input file does not reside in the current or default directory,
the path name must also be specified.
If the path name of the output file is not specified, the output file is
placed in the same directory as the input file.
