Web users often want to print the content of a page. Neat printing of the content (e.g. without having the borders cut off) can be achieved by implementing a print function and also by including stylesheets which have been optimised for printing.

The tested website does not contain specific technical implementations available on all web pages to allow content of the website to be printed, which usually leads to mistakes and imperfect printing results.

"Description" is used to summarise the content of a HTML-page as short and incisive as possible. The content of this meta information is not shown to the user in the internet browser, but search engines do use them to a certain extent to evaluate the relevance of a site for the results page.
The description summarises the content in one sentence. The summaries are normally shown on the results page of search engines and contribute a great deal to the choice of web users.

HTML is only one of a series of markup languages, though it is the best known one. HTML is relatively old and has seen various, rather different variations. The Document Type Declaration indicates which markup language and which version of it has been used. A sorting software, e.g. a web browser, can understand this indication.
Source and further information: http://de.selfhtml.org/html/allgemein/grundgeruest.htm.
The Document Type was missing in at least one of the tested pages, but not on all of them.
A table based layout carries many disadvantages if compared to a purely CSS layout. A CSS layout improves both accessibility and performance.

RSS is a technique that allows users to subscribe to contents of a website such as news, reports, blogs, etc. Atom is a format competing with RSS.
Newly published content is regularly and automatically downloaded on the subscriber's computer or other devices thanks to RSS or Atom. This allows the subscriber to keep up to date.
Functions based on RSS are increasingly integrated in existing applications, like e-mail programmes or web browsers.

DNS assigns an IP address to the names of servers on the internet. It is advisable, to increase the availability of a website, to use several name servers. RFC2182, section 5, suggests to use a minimum of 3 and a maximum of 7 name servers.Source and further information:
http://rfc.net/rfc2182.html, and http://www.rfc-editor.org/.
Acronyms:
DNS: Domain Name System
IP: Internet Protocol
The tested website contains less than three name servers.
