Margin Parameters Not Affecting Output Consistently Across PDFs

[JuhiGupta-eaton]

I’m currently facing an issue with setting margin parameters in CUPS. Despite specifying the following values, there seems to be no effect on the output:

lp -o page-right=144 -o page-left=144 -o page-top=72 -o page-bottom=72 -o media=A4 -d test /public/testpdf.pdf
I have noticed that for the attached PDF1.pdf, these settings make some margin-related difference in the printed output. However, for PDF2.pdf, there is no change.

Could someone please guide me on the usage of these options? Does the effectiveness of these settings depend on the content of the file, or are they content-independent? Am I missing something in my understanding?

Additionally, I read that by default, scale-to-fit is used. I am not using any scaling-related option. Should I be using one?

Any help would be greatly appreciated!

Thanks in advance!
