Thanks a bunch for replying, Ben! But as tomeu had pointed out, what of the schools without servers? In that case printing would have a need to be done from the laptops themselves. And personally I would definitely prefer a client-server approach as it simplifies many things. But shouldn't the print-to-pdf be a good addition? In my opinion that would at least give the kids something through which they can display their presentations to the real world. one question, the school server will be running on a normal distro, or sugar? I believe pdf printing should be present on the laptops at least, so I will push it as an end derivable. <div class="gmail_quote"> On Thu, Mar 19, 2009 at 11:12 PM, Benjamin M.

USB printer connected directly to the Sugar machine. 2. Networked printer, no server. Sugar prints directly over the network. 3. All printing passes through a server. a. networked printer with restricted access b. USB printer connected directly the server and also 1. the server may print every submission immediately 2. apply automatic quotas, or 3. require manual approval </blockquote></div>
