Editing Fax (section)

===Printing process===
Fax machines from the 1970s to the 1990s often used direct [[thermal printer]]s with rolls of thermal paper as their printing technology, but since the mid-1990s there has been a transition towards plain-paper faxes: [[thermal transfer printer]]s, [[inkjet printer]]s and [[Laser printing|laser 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 <ref>{{cite web| author=tsbmail |url=http://www.itu.int/rec/T-REC-T.30-200509-I/en |title=T.30 : Procedures for document facsimile transmission in the general switched telephone network |publisher=Itu.int |access-date=2014-02-16}}</ref>) 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.<ref>{{Cite web |last=Kang |first=Henry R. |date=2000 |title=Color Conversion between sRGB and Internet FAX Standards - |url=https://library.imaging.org/admin/apis/public/api/ist/website/downloadArticle/print4fab/16/1/art00062_2 |publisher=IS&Ts NIP16: 2000 International Conference on Digital Printing Technologies |publication-place=Peerless Systems Corporation, El Segundo, California}}</ref>
