seamless, universal print sharing and collaboration technology, need combined with advanced intelligent management technology and embedded technology, combined with the rapid increase in print resources, users print process, intelligent and networked. Early put forward the "cloud print" concept and action are the "Google cloud print" and "HP cloud printing system, they were on cloud printing technology development and layout, but did not form a unified standard system of.2010 in April, Google Cloud Print almost In the same year, in November of November, HP released cloud printing technology (HP ePrint), through the terminal device to send the mail to the cloud printer's unique E-mail address, the cloud printing function . Can be realized by Chrome in the same year in November.
At present, with the number of college students increased year by year, the number of students for printing is also increasing. The limitations of traditional print allow students to bring a series of problems in printing. College students usually print documents for homework, review papers, and all kinds of planning, analysis from the different departments and all kinds of community activities, a the most prominent feature of the students when printing is highly concentrated, generally concentrated in the campus students during the period of community defense, at the end of the review period, during the graduation thesis. In a university in Heilongjiang as an example, the number of colleges and universities in the scale of about 16000 people, the number around the campus and the surrounding print shop is only more than 10, because the university a large number of students, teachers, students of print significantly, leading students in the queue waiting to take a print and spend a long time. But some students according to print Type compatibility and other issues facing the layout problem, site layout to enable students to spend longer time, which leads to the lower efficiency of printing; according to the print shop owner reflects, as the print peak students in the face of printing problems when employee is difficult to take into account all the needs of the students, resulting in processing print longer. But through the investigation. The four print shop, we found that the non-peak appeared idle, a large number of print resources idle phenomenon. Therefore campus cloud print is essential a printed form change.
