My PDF products allow a 1/4” margin around all edges. This is usually adequate for most home printers. Check the settings in the Adobe Acrobat Reader print dialog box. Make sure you’ve selected “Actual Size” as the size option.
You may also need to adjust the Page Setup. In the print dialog box, click the Page Setup button. Look at the drop-down list of options under Paper Size. If your printer has the option, select edge-to-edge printing.
If your printer does not have that option, look at the drop-down list of printers under Format For. You may be able to select another print driver that will offer edge-to-edge printing in Paper Size. Changing the printer here will not change which printer is used when you click Print.
