Printers work in dots per inch, not pixels, so a file sized for the screen is rarely ready for paper. Preparing the image at 1748 x 2480 pixels means the printer has a real 300 DPI of detail across the full A5 sheet rather than upscaling a smaller file and producing soft edges.
At 300 DPI A5 is 1748 x 2480 pixels. At 150 DPI it is 874 x 1240, and at 72 DPI it is 420 x 595.
300 DPI is the standard for photo and document printing. 150 DPI is acceptable for large posters viewed from a distance, and 72 DPI is screen only.
