Why are the page sizes obtained from reading a document different from those obtained from creating a new document?

I don't understand what you are doing or even what you mean. You little function as such seems to do what you want - see following post.
But first I will transfer this to "Discussions" because it definitely is not bug.

This works fine:

import pymupdf


def draw_test_pattern(page, label):
    shape = page.new_shape()

    # 画边框
    shape.draw_rect(page.rect)
    shape.finish(width=2, color=(0, 0, 0))

    # 画四个角的圆圈
    for x, y, color in [
        (0, 0, (1, 0, 0)),  # 左下 - 红
        (0, page.rect.height, (0, 1, 0)),  # 左上 - 绿
        (page.rect.width, 0, (0, 0, 1)),  # 右下 - 蓝
        (page.rect.width, page.rect.height, (1, 1, 0)),  # 右上 - 黄
    ]:
        shape.draw_circle((x, y), 20)
        shape.finish(fill=color)
        shape.insert_text(
            (x + 25, y + 25), f"{label} ({x:.0f}, {y:.0f})", fontsize=12, color=color
        )

    shape.commit()


doc1 = pymupdf.open("normal.pdf")
draw_test_pattern(doc1[0], "Pattern")
doc1.save(doc1.name.replace(".pdf", "-new.pdf"))

doc2 = pymupdf.open("PrintPic.pdf")
draw_test_pattern(doc2[0], "Pattern")
doc2.save(doc2.name.replace(".pdf", "-new.pdf"))

BTW please stop using the deprecated import name "fitz".
If you have old applications where conversion would mean a large effort use import pymupdf as fitz.

My output is perfect:
Printpic.pdf:
