The Hoe Machine turns out 7000 impressions printed on both sides in the hour, whereas the Walter Machine turns out 12,000 impressions completed in the same time.
The new Walter Press does not in the least resemble any existing printing machine, unless it be the calendering machine which furnished its type.

At the printing end it looks like a collection of small cylinders or rollers.

The first thing to be observed is the continuous roll of paper four miles long, tightly mounted on a reel, which, when the machine is going, flies round with immense rapidity.

The web of paper taken up by the first roller is led into a series of small hollow cylinders filled with water and steam, perforated with thousands of minute holes.

By this means the paper is properly damped before the process of printing is begun.
