Sticky labels are also available in standard paper sizes for use in standard office printers. Standard office automation products such as word processors and databases can be set up to produce mailing labels using these label sheets. Overhead projectors Overhead projectors advanced considerably in the 1990s from the old-fashioned early transparency projectors. While transparency projectors are still available and useful, more advanced projectors can project images directly from a computer onto overhead wide screens. Electronic computer projectors, coupled with presentation software, can deliver very sophisticated presentations.
Overhead projectors can project words, data, drawings, photographs, animations and video.
Coupled with speakers, sound can be added to presentations. Overhead projectors are widely used by EMBs for training, presentations and seminars. Projectors can also be used at public election events such as declarations of candidates, ballot draws or results. Many kinds of wide screens are available to display television and video output in a large format suitable for large audiences. This facility can be useful for training large numbers of polling officials, for example.
