Sorry about missing the 100% - It still seems that there is something else at work and needs to be adjusted. It took many tries to get all of my info on the sheet and be inside the max allowable print area. If you are using a typical plotter as HP or similar and the available size including the space for the printer's margins is visible on the layout book sheet and there isn't anything hanging - there is no apparent solution. If however, all of the variables have not been tested, then other options need to be tried.
