I'm wondering what you mean by 'letters redistributing themselves'.
If you are referring to a programme such as Word or Office Writer (word processing programme, there are a couple of settings that may be relevant.
There is 'widows and orphans' control which prevents the splitting of paragraphs across more than one page. That means that you may not get a page break where you expect.
Similarly, justification settings (centered, left, right) may cause a line to appear differently to your expectation.
Otherwise, I don't know what you mean. The l
