Looking for software to divide a A4 page into multiple parts ?

I want to print the circuit diagram of the pdf file, I have a canon 2900 printer that only prints A4 size paper, if I print A4 size I cannot see the word for the circuit diagram, do you know what software I can divide a A4 page into many parts, for example, if I want to print a A2 page, I have to divide the A4 page into 4 parts. I myself want to print in A3 size, the software automatically divides into 2 parts of A4 size. After printing, I merge it into A3, I use Acrobat Reader DC with no function of dividing A4 pages into multiple parts or vice versa, I couldn't find the software question, so I put it here.

First, open the PDF file that you want to break into different parts. Click on the Tools pane, Pages panel and select the Split Document command. The Split Document dialog allows you to control the split by the number of pages in a file, file size, or by top-level bookmarks

Hope this information is helpful to you
