Hi Michael, Thanks for contacting us. 1000×1400 is correct for 5×7″. The key will come down to your printer settings just before printing. Try opening up the Printer Settings dialog and ensuring that the correct paper size is selected. I’m not sure why it’s printing as 6×7 as the proportion of 1000:1400 is 5:7. Is it stretching the image when printing, or cropping it? Either way, it should be resolvable through the printer settings. Let us know if we can be of any further assistance!
