Royal Earl House was the inventor of the first printing telegraph
Printing telegraph
The Printing Telegraph was invented by Royal Earl House in 1846.The device was made by linking two 28-key piano-style keyboards by wire. Each piano key represented a letter of the alphabet and when pressed caused the corresponding letter to print at the receiving end. A "shift" key gave each main...

 by wire. Each piano key represented a letter of the alphabet and when pressed caused the corresponding letter to print at the receiving end. A "shift" key gave each main key two optional values. A 56-character typewheel at the sending end was synchronised to coincide with a similar wheel at the receiving end. If the key corresponding to a particular character was pressed at the home station, it actuated the typewheel at the distant station just as the same character moved into the printing position, in a way similar to the daisy wheel printer
Daisy wheel printer
Daisy wheel printers use an impact printing technology invented in 1969 by David S. Lee at Diablo Data Systems. It uses interchangeable pre-formed type elements, each with typically 96 glyphs, to generate high-quality output comparable to premium typewriters such as the IBM Selectric, but two to...

. It was thus an example of a synchronous data transmission system. House's equipment could transmit around 40 instantly readable words per minute, but was difficult to manufacture in bulk. The printer could copy and print out up to 2,000 words per hour. This invention was first put in operation and exhibited at the Mechanics Institute in New York in 1844.

In 1886 and 1887, when the Royal E. House telegraph company was producing the printing telegraph, the Morse Telegraph company tried to enjoin (legally prevent) them from infringing on the Morse patents. Morse claimed the sole right of transmitting intelligence by electricity, utilizing the Morse code

. The courts decided the House Company did not infringe the Morse patent, as the messages using the House system were all printed on a slip of paper, without the use of Morse Code.

Later the House Co. and the Morse Co. joined and formed the Great Western Telegraph Company.
