## Add page break in output
In older Tesseract (before September 2017) use the config variable as part of command `-c include_page_breaks=1 -c page_separator="[PAGE SEPARATOR]"`
Default page separator is the form feed control character.
`tesseract -c include_page_breaks=1 input.tiff output`
In newer Tesseract (after September 2017) the `include_page_breaks` config variable has been removed. The default is now to separate pages with the form feed control character. Use `-c page_separator="[PAGE SEPARATOR]"` to use a different separator, and `-c page_separator=''` to disable page breaks entirely.
## OCR multiple images with one run of tesseract
Prepare a text file that has the path to each image:
```
path/to/1.png
path/to/2.png
path/to/3.tiff
```
Save it, and then give its name as input file to Tesseract.

## OCR single page of a multi-page tiff
Use the config variable as part of command `-c tessedit_page_number=0 `
## Integrate original image file and detected text into PDF
Use the config variable `-c textonly_pdf=1` and Merge your image-only and text-only PDF.
