In Print Settings, under printer properties, make dang sure you're using 8.5 x 11 and not A4 or something like that. Also, make sure any scaling/zoom options are at 100% or less. Try less if you have to.
If I were going to ""hack"" at this, I'd insert a very skinny column at the left (new column A) and see if that helps. Try setting your left margin to a slightly wider value. Set it to print in landscape mode and see what happens.
Just guessing at this point.
