Although both V.17 and V.34 tend to add a few hundred dollars to a machine's cost, they often pay for themselves if your company faxes more than 30 pages a day. You can only use the high speeds through V.17 and V.34 when transmitting to other fax machines that have the same protocols. However, V.17 and V.34 machines are equipped with a fallback mechanism that lets them send and receive at 9,600 bps to ensure that they stay compatible with older machines. Data compression protocols Simply put, data compression protocols reduce the time it takes to send a page by describing it with a minimum amount of data. You can reduce transmission costs by buying a machine with advanced data compression protocols.
Some machines use their own sending or compression protocols to increase the speed of transmission.
However, you should know that these protocols only work when sending to or from same-brand models. Unless you frequently fax between two offices with the same type of machine, you won't noticeably reduce your overall sending costs with such brand-specific compression systems. Printing You can choose from a few types of fax printing technologies. Thermal Most older and cheaper fax machines use thermal printing. This means that a small heating element within the machine is used to mark heat-sensitive paper.
