Binds a variable to either
t
or
nil
, and executes a body of code to print a page only if the variable is
t
.
The
with-page
macro binds
printp
to
t
if a page is to be printed, or
nil
if it is to be skipped. The
body
is executed once, and is expected to draw the document only if
printp
is
t
.
Each call to
with-page
contributes a new page to the document.
