Fax printers. One of the advantages of inkjet printing is that inkjets can affordably print in color; therefore, many of the inkjet-based fax machines claim to have color fax capability. 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 usually another fax machine, which then transforms these pulses into images, and prints them on paper. The traditional method requires a phone line, and only one fax can be sent or received at a time. The phone connection must not be a packet-based system in which delays can occur—a VoIP connection will not work well without special precautions (T.38-compliant equipment at both ends). Internet fax achieves a dramatic reduction in communication costs especially when long faxes are frequently exchanged with overseas or distant offices. Since there is no telephone connection charge when sending a fax over the Internet, the cost
