Printing has a long heritage with the Chinese first using woodblock printing way back to 220 A D. Contemporary printing started with Johannes Gutenberg in the late 1400's and developed to the advanced printing presses of today, called moveable printing with offset printing, of which the lithographic process is regarded as the commonly used.
Printing also developed beyond the application of big printing presses, ordinarily employed to print big quantities of books, magazines, newspapers and the like, to incorporate many other methods and uses. Printing has developed to the stage where it has become everyday and taken for granted, while in reality it has a long history of different periods of development as a means of transferring words and images to paper and other components using ink as well as some transfer process.
There are various printing techniques for various applications: papers, publications, cardboard boxes, office communication, T shirts, take your pick and we can print it. Just looking at the office, small business and home printing applications unearths some interesting types of printing. Looking at an architect's or an engineer's office for example, where plans and complex drawings are designed, it is intriguing to watch those specific printers in operation. It is only ten when one appreciates the complex arrangement and the technology helpful to produce such drawings, particularly when there is colour printing required. Normal office printing, particularly in the small company environment includes printing of both words and images. Think about the technology and design logic associated with printing on a single sheet of paper, words, and images like a logo - in colour - and possibly a copy of a photo.
You in reality, can print anywhere today, wherever there is a printer, making the mobile business office a total reality. In the example of a travelling business person, technology allows us to be able to communicate to the outside world with our computer systems, using the web even from our cars. So, it is imaginable that an urgent letter to someone is transmitted to your laptop or iPad, while you are driving and having a mobile printer you can print that page and hand deliver it to your client.
