There is a standard called ITU-T30e (formally ITU-T Recommendation T.30 Annex E ) for faxing in color; however, it is not widely supported, so many of the color fax machines can only fax in color to machines from the same manufacturer. Stroke speed in facsimile systems is the rate at which a fixed line perpendicular to the direction of scanning is crossed in one direction by a scanning or recording spot.
Internet fax to send faxes directly. Instead of first printing a hard copy to be then sent via fax machine, a document could now be printed directly to the software fax, then sent via the computer's modem. Receiving faxes was accomplished similarly. A disadvantage of receiving faxes through the computer is that the computer has to be turned on and running the fax software to receive any faxes. It also means that the document is no longer readable by computer applications, unless optical character recognition methods are used to read the fax image. Note: This method is distinct from Internet faxing as
