Output page justification

I have several web pages saved as PDF which generally turns them into very tall pages. All the applications I tried on Ubuntu (I know it is different for Windows & Mac) want to format printer output onto a single page, and no matter what I tried, I was never given a tiling option to split this tall page into several 'printer' sized pages.

PDFposter can split this long page into multiple pages suitable for printing, however, it always "bottom justifies".

I would like to make a suggestion to add a "-j" switch, where the user can select what justification they desire... for example T (top), M (middle), B (bottom), L (left), C (center), R (right). At present the output is "B".

I used "pdfposter -vvv -p1x999a4 financialcrime.pdf split.pdf" to create the following. For my use, I would prefer "-jT".

If the -s (scale) option is used so the output is not exactly a page width multiple, the ability to left/center/right justify that output would be something useful as well.
