Sets whether you want to print a header in each page. The
header consists of three pieces of text and an optional line
separator, configurable with
gtk_source_print_compositor_set_header_format().
Note that by default the header format is unspecified, and if it's
empty it will not be printed, regardless of this setting.
This function cannot be called anymore after the first call to the
gtk_source_print_compositor_paginate() function.
Since 2.2
