    Because the "fields" (blank spaces) are the same location every

    script.

    I used to do something similar for filling out my GST return, only using a Python script and the Cairo graphics library -- import each page of the
    PDF file, draw the filled-in entries on top of it, and print the result
    out.

    I did routines for things like splitting out the digits of a number so
    each would fit, nicely centred, in its own box -- does LaTEX make this
    sort of thing easy?

    I wrote a couple of macros to do this. Not hard, but fiddly, and most
    forms are internally inconsistent in that the digit boxes are not always
    the same size or shape. OCR forms are better. Fortunately becoming less
    and less common these days.

    This wasnrCOt hard in Python. Even if the digit boxes werenrCOt regularly arranged (they were), it would just have meant manually specifying the coordinates of each box.
