I've designed a leaflet to be emailed to different companies who are willing to display it for me. It's an A4 book fold leaflet. My problem is that I have made it A4 size in photoshop but when trying to print it on my printer the margins spoil it and the margin settings are greyed out. What I'm actually after is the leaflet to cover the whole page and be sure when I email this leaflet to anyone they can print it out properly. What is the best format also to save this leaflet in for people to print out. Thanks in advance for your help.
