Hi! This usually points to a printer/driver or print scaling setting on that specific PC, not to the PowerPoint file itself, because you already confirmed the same presentation prints without side margins on another computer. The most common causes are the printer being set to a different paper size than the slide/output size, a driver option like Fit to printable area / border handling/scale to paper, or the printer using a non-borderless printable region on that machine.
In PowerPoint > File > Print, recheck that the selected printer is the same one and that paper size in Printer Properties matches A4 exactly; then open Printer Properties/Preferences and look for options such as Borderless printing, Fit to page, Shrink oversized pages, Scale, Printable area, or driver-specific margin correction, and disable any extra scaling. Also test Microsoft Print to PDF or Save as PDF first; if the PDF has no side margins, the issue is almost certainly the physical printer driver on that PC. If needed, remove and reinstall/update that printer driver, because PowerPoint itself is less likely to be the cause when another computer prints the same file correctly.
