Note, that this will not be pure JPEG-file, but JPEG incapsulated in TIFF. Other compression methods, like PackBits, will give you better results for your 1-bit images.
If you want to produce pure JPEG-images you need other tools, for example, ImageMagick (http://www.imagemagick.org/):
I think you mean JFIF (.jpg) intsted of "pure JPEG".
JPEG is a compression method, not a file format.
JPEG compression is used in a wide variety of formats (TIFF, NITF, JFIF, BMP(*), etc.).
JFIF is a file format that only supports JPEG compression.
Other formats support other types of compression in addition to JPEG compression.
(*) ok, I have seen a spec for this, but have never seen an actual JPEG BMP in the wild.
