I need to make a document 2m wide to ensure no pixelation, at 55cm I get a line feed and carriage return, I cannot switch that off?
By observation, it looks like 1.19 m is the widest page before strange things happen to text wrapping.
The most extreme appears to happen at 1.20 m where the wrap occurs at around 4 mm.
