最早的印刷技术是用硬金属来制作符号的复制品。这种坚硬的金属被用来制造主型冲床，这是在公元前3000年古苏美尔发展起来的。这些打孔机可以被认为是字母打孔机的鼻祖，字母打孔机后来起源于活字印刷。在美索不达米亚，湿粘土被用来印刷字母，在湿粘土的表面上滚上圆筒印章。钢瓶密封件的主要用途是标记所有权对象或签署文件。公元前650年，古希腊人开始使用直径较大的冲头。这些冲孔机被用来在那个文明的标志和硬币上打印图像。第一个设计的硬币穿孔机被巧妙地程式化，这样它就可以用同样的设计复制更多的硬币。第一个字体,它被用来印刷的书通过纸张和油墨在13世纪被起诉,但是硬币类型是不同的,因为他们是用来做永久纪念的金属(金属是更耐用纸张),因此这样的硬币可能生存时间的应变。

印刷的硬币被认为是文明和贸易之间的媒介。印章也可视为活字的起草人。一些考古学家认为，在美索不达米亚文明的乌鲁克和拉尔萨市发现的砖制邮票是用活字印刷的。一位学者还指出，公元前1800年至1600年神秘的米诺斯菲斯托斯盘是最早的文本之一，它是用可移动的字符或可重复使用的字符印刷的。人们还认为，这可能是通过将预先成形的象形文字印章压入湿粘土而印刷出来的。这种光盘被认为符合通过可移动印刷开发的所有标准。以前所有的写作工作都是手工完成的。书卷是用手写的，如果需要抄写，作者就必须用手再写一遍。这种复制品非常昂贵，只有富人才能买得起。纸也是中国在公元2世纪汉代发明的。木版印刷最早出现在中国，大约在公元650年的唐朝。

The very first technique of printing use to form copies of symbols was made with the use of hard metal. This hard metal was used to make the master type punch, and this was developed in ancient Sumer in 3000 BC. These punch type can be considered as the originators of the letter punches, which later originated to print with movable type. In Mesopotamia, the wet clay was used on which letter were printed with cylinder seals that were rolled over the surface of the wet clay. The main use of the cylinder seals was to mark the object for ownership or to sign the documents. By 650 BC, the people from ancient Greek had started using punches with large diameters. These punches were used to print images on tokens and coins of that civilization. The very first coin punch, which was designed, was skillfully stylized so that it can be used to reproduce more coins with the same designs. The first typefaces, which were used to print the books in thirteenth century were sued through paper and ink, but the coin types were different as they were used to make permanent mark on the metal (metal was more durable then paper) and thus such coins could survive the strain of time.

The printed coins were considered to be the medium between the civilization and trade. Seals and stamps can also be considered as the originators of the movable type. The brick stamps found in the cities of Uruk and Larsa from the Mesopotamian civilization are believed to be made through movable type according to some archeologists. One of the scholars has also stated that the mysterious Minoan Phaistos Disc of 1800–1600 BC is one of the early examples of the text, which have been printed with movable characters or the reusable characters. It is also believed that this may have been printed by pressing the pre formed pictograph seals into the wet clay. This disc is considered fulfilling all the criteria of being developed through movable printing. Earlier all the writing work was done by hands. The scrolls of writings were prepared with hands, and in case if the copy of the scroll was required, then writer had to write it again with hands. Such copies were very costly and could only be afforded by rich people. The paper was also invented in China during second century AD at the time of Han Dynasty. Wood block printing was first developed in China during the period of Tang Dynasty close to 650 AD.
