Printing eBay invoice/labels on printer via MacBook

[Varsani]

Hi, 

I run an eBay business, I bought the printer to be able to print address labels on a label template a4 sheet from my MacBook. 
The A4 sheet already has the label sticker in position: the nightmare has been trying to adjust printer margins on the Mac to enable the pdf page from eBay with the address on it to fall exactly on the label. 
I’ve been struggling for a while. I’m reading about custom pages but it’s an A4 size sheet I’m printing on. Adjusting the ‘top’ of unprintable area doesn’t make any difference or it makes the scale adjust smaller which I don’t want, as can barely read the address. 
Please help me!
