" <p>If you enable this option, you can print posters of different sizes "
" The printout will happen in the form <em>'tiles'</em> printed on smaller "
" paper sizes, which you can stitch together later. <em>If you enable this "
" option here, the <em>'Poster Printing' filter</em> will be auto-loaded in "
" the 'Filters' tab of this dialog. </p>"
" <p>This tab is only visible if the external <em>'poster'</em> utility is "
" discovered by KDEPrint on your system. [<em>'poster'</em> is a commandline "
" utility that enables you to convert PostScript files into tiled printouts "
" which allow for oversized appearance of the stitched-together tiles.] </p>"
" <p><b>Note:</b> The standard version of 'poster' will not work. Your system "
" must use a patched version of 'poster'. Ask your operating system vendor to "
" provide a patched version of 'poster' if he does not already. </p>"

" <li>Either use the interactive thumbnail preview above and '[SHIFT]-click' on the tiles. </li> "
