List of files drwxrwxr-x. 2 aia aia   23 Jun 14 12:06 pvz

Expanding on what Scrutinizer said... As already explained in this thread, this only works if IFS is set to the <newline> character.

With a default setting of IFS (IFS=$' \t\n'), that command would produce something more like:
Code:
List of files total
List of filesl 12
List of files -rw-rw-r--.
List of files 1
List of files aia
List of files aia
List of files 148
List of files Jun
List of files 7
List of files 19:49
List of files index.html
... ... ...

And, you get the same results with:
Code:
IFS=$'\n' printf "List of files %s\n" $(ls -ltr)

because that only sets IFS in the environment for the invocation of printf; not for the evaluation of the results of the command substitution done in the current shell execution environment when preparing arguments to be passed to printf.

paps

PAPS(1) 						      General Commands Manual							   PAPS(1)

NAME

       paps - UTF-8 to PostScript converter using Pango

SYNOPSIS

       paps [options] files...

DESCRIPTION

       paps reads a UTF-8 encoded file and generates a PostScript language rendering of the file. The rendering is done by creating outline curves
       through the pango ft2 backend.

OPTIONS

       These programs follow the usual GNU command line syntax, with long options starting with  two  dashes  (`-').   A  summary  of  options	is
       included below.

       --landscape
	      Landscape output. Default is portrait.

       --columns=cl
	      Number of columns output. Default is 1.

       --font=desc
	      Set the font description. Default is Monospace 12.

       --rtl  Do rtl layout.

       --paper ps
	      Choose paper size. Known paper sizes are legal, letter, a4. Default is A4.

       --bottom-margin=bm
	      Set bottom margin in postscript points (1/72 inch). Default is 36.

       --top-margin=tm
	      Set top margin. Default is 36.

       --left-margin=lm
	      Set left margin. Default is 36.

       --right-margin=rm
	      Set right margin. Default is 36.

       --help Show summary of options.

       --header
	      Draw page header for each page.

       --markup
	      Interpret the text as pango markup.

       --encoding=ENCODING
	      Assume the documentation encoding is ENCODING.

       --lpi  Set the lines per inch. This determines the line spacing.

       --cpi  Set the characters per inch. This is an alternative method of specifying the font size.

       --stretch-chars
	      Indicates  that  characters  should be stretched in the y-direction to fill up their vertical space. This is similar to the texttops
	      behaviour.
