Re: Choose paper size and layout with command line options?

[M Sun]

Thanks Knute. The problem is not only the paper size, but also this part:

  #(set-global-staff-size 18)
  \paper {
    top-margin = 0
    bottom-margin = 0
    left-margin = 5
    right-margin = 0
  }

I need to enable these with the "kobo" size, but not in us-letter.
