A lot of the plans I’ve found are already in the big sheets and not tiled out to print on a normal office printer and even when I try printing the tiled versions a lot of the time it doesn’t match up perfectly so does anyone know where I could maybe print out the full sized versions?
Every home printer I've used in the last 20 years has "print preferences" in that section there is settings for "poster" , I can make it smaller, bigger, with cut lines, or without, print preview to see how many pages, landscape or portrait.
I don't hear about many people doing it this way, not sure why, for me it's easy and straightforward.
