Under these circumstances, it appeared to Koenig that only two alternatives remained for him to adopt. One was to commence an expensive, and it might be a protracted, suit in Chancery, in defence of his patent rights, with possibly his partner, Bensley, against him; and the other, to abandon his invention in England without further struggle, and settle abroad. He chose the latter alternative, and left England finally in August, 1817.

Mr. Richard Taylor, the other partner in the patent, was an honourable man; but he could not control the proceedings of Bensley. In a memoir published by him in the 'Philosophical Magazine,' "On the Invention and First Introduction of Mr. Koenig's Printing Machine," in which he honestly attributes to him the sole merit of the invention, he says, "Mr. Koenig left England, suddenly, in disgust at the treacherous conduct of Bensley, always shabby and overreaching, and whom he found to be laying a scheme for defrauding his partners in the patents of all the advantages to arise from them. Bensley, however, while he destroyed the prospects of his partners, outwitted himself, and grasping at all, lost all, becoming bankrupt in fortune as well as in character."[6]

Koenig was badly used throughout. His merits as an inventor were denied. On the 3rd of January, 1818, after he had left England, Bensley published a letter in the Literary Gazette, in which he speaks of the printing machine as his own, without mentioning a word of Koenig. The 'British Encyclopaedia,' in describing the inventors of the printing machine, omitted the name of Koenig altogether. The 'Mechanics Magazine,' for September, 1847, attributed the invention to the Proprietors of The Times, though Mr. Walter himself had said that his share in the event had been "only the application of the discovery;" and the late Mr. Bennet Woodcroft, usually a fair man, in his introductory chapter to 'Patents for Inventions in Printing,' attributes the merit to William Nicholson's patent (No. 1748), which, he said, "produced an entire revolution in the mechanism of the art." In other publications, the claims of Bacon and Donkin were put forward, while those of the real inventor were ignored. The memoir of Koenig by Mr. Richard Taylor, in the 'Philosophical Magazine,' was honest and satisfactory; and should have set the question at rest.

It may further be mentioned that William Nicholson,—who was a patent agent, and a great taker out of patents, both in his own name and in the names of others,—was the person employed by Koenig as his agent to take the requisite steps for registering his invention. When Koenig consulted him on the subject, Nicholson observed that "seventeen years before he had taken out a patent for machine printing, but he had abandoned it, thinking that it wouldn't do; and had never taken it up again." Indeed, the two machines were on different principles. Nor did Nicholson himself ever make any claim to priority of invention, when the success of Koenig's machine was publicly proclaimed by Mr. Walter of The Times some seven years later.

When Koenig, now settled abroad, heard of the attempts made in England to deny his merits as an inventor, he merely observed to his friend Bauer, "It is really too bad that these people, who have already robbed me of my invention, should now try to rob me of my reputation." Had he made any reply to the charges against him, it might have been comprised in a very few words: "When I arrived in England, no steam printing machine had ever before been seen; when I left it, the only printing machines in actual work were those which I had constructed." But Koenig never took the trouble to defend the originality of his invention in England, now that he had finally abandoned the field to others.

There can be no question as to the great improvements introduced in the printing machine by Mr. Applegath and Mr. Cowper; by Messrs. Hoe and Sons, of New York; and still later by the present Mr. Walter of The Times, which have brought the art of machine printing to an extraordinary degree of perfection and speed. But the original merits of an invention are not to be determined by a comparison of the first machine of the kind ever made with the last, after some sixty years' experience and skill have been applied in bringing it to perfection. Were the first condensing engine made at Soho—now to be seen at the Museum in South Kensington—in like manner to be compared with the last improved pumping-engine made yesterday, even the great James Watt might be made out to have been a very poor contriver. It would be much fairer to compare Koenig's steam-printing machine with the hand-press newspaper printing machine which it superseded. Though there were steam engines before Watt, and steamboats before Fulton, and steam locomotives before Stephenson, there were no steam printing presses before Koenig with which to compare them, Koenig's was undoubtedly the first, and stood unequalled and alone.

The rest of Koenig's life, after he retired to Germany, was spent in industry, if not in peace and quietness. He could not fail to be cast down by the utter failure of his English partnership, and the loss of the fruits of his ingenious labours. But instead of brooding over his troubles, he determined to break away from them, and begin the world anew. He was only forty-three when he left England, and he might yet be able to establish himself prosperously in life. He had his own head and hands to help him.

Though England was virtually closed against him, the whole continent of Europe was open to him, and presented a wide field for the sale of his printing machines.

While residing in England, Koenig had received many communications from influential printers in Germany. Johann Spencer and George Decker wrote to him in 1815, asking for particulars about his invention; but finding his machine too expensive,[7] the latter commissioned Koenig to send him a Stanhope printing press—the first ever introduced into Germany—the price of which was 95L. Koenig did this service for his friend, for although he stood by the superior merits of his own invention, he was sufficiently liberal to recognise the merits of the inventions of others. Now that he was about to settle in Germany, he was able to supply his friends and patrons on the spot.

The question arose, where was he to settle? He made enquiries about sites along the Rhine, the Neckar, and the Main. At last he was attracted by a specially interesting spot at Oberzell on the Main, near Wurzburg. It was an old disused convent of the Praemonstratensian monks. The place was conveniently situated for business, being nearly in the centre of Germany. The Bavarian Government, desirous of giving encouragement to so useful a genius, granted Koenig the use of the secularised monastery on easy terms; and there accordingly he began his operations in the course of the following year. Bauer soon joined him, with an order from Mr. Walter for an improved Times machine; and the two men entered into a partnership which lasted for life.
