OK, we're getting somewhere! I figured out that the Ubuntu repo just doesn't work properly with tiffs, and recompiled and installed tesseract and leptonica.
So now when I run tesseract -v, I get: ↪ tesseract -v tesseract 3.02.02 leptonica-1.69 libjpeg 8b : libpng 1.2.46 : libtiff 3.9.5 : zlib 1.2.3.4 Whereas previously, I didn't get anything mentioning libtiff. >From there, I ran the convert command on the stackoverflow post: convert -depth 4 -density 300 -background white -flatten +matte united_states_v._ups_customhouse_brokerage_inc..pdf united_states_v._ups_customhouse_brokerage_inc2.tiff The resulting file worked well with tesseract, but it only had the last page of the PDF...so it's close -- very close -- but not quite there yet.
