Laser printers are common print output products in our daily office. From 1975 IBM 3800 became the world’s first laser printer. By March 28, 2018, HP announced the launch of the world’s smallest laser printer LaserJet Pro M15 black and white laser. Printers, 43 years later we found that laser printers are getting smaller and smaller.
As Mr. Lu Xun said: In fact, there is no road on the ground. There are many people who have gone and it has become a road. Starting from the development of printing products, it was originally designed to cope with the large amount of document output and to reduce the labor cost of typists. With the increasing number of companies with literary and cultural needs, compact and lightweight laser printing products have emerged and are rapidly accepted by business users.
Laser printers come this way?
Desktop laser printer is converted from a copier, the copier experienced a photochemical reaction, after the reform of photovoltaic systems technology imaging, but still only a 'copy' this function, because the computer is definitely less at that time, there was no will The need for computer data to print out.
Time to 1969, the great Xerox appeared, charging exposure step before copying its R & D staff just want to reach volume production of standard laser alternative, draw the image directly on a photosensitive drum, this way you can significantly reduce the volume of the products, So that more companies accept, purchase, use.
In 1972, the Xerox was still a big friend of Xerox. He added a control system and character generator to his colleagues on a Xerox multifunction machine. He eventually produced the world's first laser printer 9700.
However, due to problems with product recognition and future market judgments, the world’s first mass-produced laser printer was taken away by the IBM 3800, which resulted in the IBM printing department and the current Lexmark.
Desktop products still rely on Canon
Whether Xerox's 9700 or IBM's 3800, the advantages and disadvantages of these original laser printers are equally obvious. They are fast, bulky, and expensive, which makes it impossible for some companies with literary and cultural needs to purchase and install them.
According to the information we have collected, only the U.S. government and a handful of resource-monopoly companies purchased these 'giants' at that time, and even because of the high cost of use, there was even a strange phenomenon of recruitment of typewriters.
1980 became a key year for desktop printers. Canon made two major events for the printing industry this year. It is widely known that Canon released the first inkjet printer Y-80 with thermal foam print heads. But Canon CX OEM, a Canon laser print engine introduced in the same year, paved the way for a small desktop laser printer.
Although Canon's CX calibre sells for only 1,000 US dollars compared to the finished product, this caliber, which is not even available from the power supply, is still much higher than other movements of the same period. At this time, there is a desktop-level gamble. In front of many printing equipment manufacturers, who pays more attention, the future may achieve a dominance, but the loss of failure is not affordable for all companies.
The soon-to-be companies that saw the goods, and bet on Canon CX OEMs, they were Hewlett-Packard and Apple. In 1984, Apple introduced its LaserWriter series of laser printing products using Canon CX OEM movements, and through its own advantages, optimized its The gamma value of the print product is matched with the output of Apple's monitor.
In the same year as Apple LaserWriter series laser printing products were released, Hewlett-Packard introduced LaserJet series laser printer products based on Canon CX OEM, and successfully obtained a blood of a desktop laser printer.
Unlike Apple's modified Gamma value for output matching optimization, HP chose the general public to change the continuous paper of a conventional laser printer to a sheet of paper so that the printed document can be used without cutting.
Coupled with the introduction of free PCL printing language in the 1930s (Adobe's PostScript printing language was a charge), it was rapidly accepted and purchased by businesses with literary printing requirements, laying the foundation for today's Hewlett-Packard half of the desktop laser printer market. status.
How small is the smallest in the world?
Time to return to March 28, 2018, HP released the world's smallest black and white laser printer LaserJet Pro M15 in the end how small it?
According to currently published data, the HP LaserJet Pro M15 has a volume of 190.5mm x 345.4mm x 160mm and a net weight of 3.8kg. It is 29% smaller than Fuji Xerox's products in the market, and its floor space is 7% less.
In terms of product performance and functionality, HP LaserJet Pro M15 has a nominal output speed of 18 ppm, a maximum physical print resolution of 600 dpi x 600 dpi, a maximum monthly print load of up to 8,000 pages, and a 150-sheet paper feed unit. 8MB memory and 500MHz processor, no doubt meet the daily printing needs of office users.
From 1975 to 2018, we not only saw the development of miniaturization of laser printing products, but also saw the hard work of generation after generation of OA. It is precisely this group of people who can Let this industry go further and further towards the path of healthy development.
