Upload one photo, choose how many rows, then print straight to your Epson L3350 over WiFi.
• 1 row = 5 photos (fits your original ask). A4 fits up to 6 rows = 30 photos on one sheet, if you want to fill the page and save paper.
• In the print dialog: set Margins → None, Scale → 100% / Actual size (not "Fit to page"), and paper size A4. Turn off "Headers and footers".
• Photo is cropped (not stretched) to fill each 35×45mm cell, same as a passport photo booth.
