IPEX started in 1912 when Hajj Omar Mneimneh established the National Press, which was in Marce-lias Street, Downtown, Beirut. He started the process of printing for major local newspapers which are still existing till today, such as "Al Nahar”, "Al Hayat”, and "Al Hadaf”, "Al Huda”, "Al Yawm”, and "Al Sahafa Fi Al Taeh”.

In 1934, Hajj Omar signed a contract with the great journalist Mr. Jobran Toueni as was stated in "Al Nahar” newspaper to start printing ''Al Nahar'' newspaper. After that in 1936, the press moved to "Ayyas” market to print the first edition of "Al Hayat” newspaper. Since then, IPEX has been holding the biggest double sided printing machines designed for such uses.

In 1951, the new generation printing emerged when Issam Omar Mneimneh joined his father in the journey to develop the press in a new base located in Bashoura street - Beirut. The press was equipped with the first printing automated machines, known as Heidelberg. In 1965, Issam started a new stage in sorting and printing books using the Intertype and the Monotype, in addition to the colored commercial prints.

After this long journey, it was the grandchildren's turn to continue what their grandparent had started. They started working with their father on the offset machines. By 1998, IPEX had thrived further equipped with latest advanced machines and computers for designing, sorting, and binding books & magazines, including various kinds of commercial, 8 & 4 color printing machines. 

IPEX continues to develop to keep up with the technological advancement. It is now considered one of the top printing press groups in Lebanon, offering services across various fields:  Prepress Graphic Design, Printing Press, Post press, finishing, Digital Printing, and Copy & Print Centers.
