Printing telegraph

A Printing Telegraph Set built by Siemens & Halske in Saint Petersburg, Russia, ca.1900

The printing telegraph was invented by Royal Earl House in 1846. House's telegraph 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.[1][2]
