HP Deskjet 1512 Not Properly Printing A4 Format

[Gob-Sauce]

I'm trying to print out a leather pattern, though it keeps cutting out a part of the rest page. It supposed to be printed using A4 formatting, but it doesn't seem to print right. When I do mess with it, and get the whole page to print, it still prints undersized by about 1/5 of an inch.

Update: After messing around, it turns out its a strange software issue,

The problem in my case, boils down to the fact that some pages were landscape and others were portrait. For some reason, this causes the system to have a massive stroke, and print the pages that were meant to be in landscape in portrait. 

My solution was rather crude, as it involved me finding a PDF editor, and then separating the portrait and landscape pages, and printing the two types separately. In other words, I printed the Portrait pages separate from the Lanscape pages. I hope this issue gets fixed, as it's a royal pain to do this. 

Thank you to the (at the time of writing, 60 people) who saw this. Hope y'all are doing well, that you're 2022 is off to a great start, and hope one of you folks found an answer.
