Alois Auer was appointed direct of the printing office of the
k. k. Hof- und Staatsdruckerei, the Austrian state printing facility in Vienna.

He also promoted the printing facility by issuing a series of books about the printing house itself.
One of Auer's most significant contributions was a "typometrical system," standardizing the sizes of the large number of foreign alphabets that he had ordered cast. This he described and illustrated in
