Large format printers are a very convenient and often indispensable tool in producing hard copies of digitalized images such as technical drawings, paintings, maps, and office documents. It is an important part of electronic document management, in which the first step is scanning. So it is, in many cases, desirable to have printers with scanning capabilities. This need is all the more evident when it is required to produce enlarged images from drawings stored on microfilm. The conversion of actual drawing into microfilm requires a scanner with medium resolution. But when a microfilm is being scanned, it must be done at very high resolution so as to have good image quality in the print and to show the details in an enlarged copy. The printer is generally of inkjet type. UV curable inkjet printing is a relatively new technology in printing.
HP DesignJet 815 MFP is a printer-scanner with a resolution of 2400×1200 dpi. This makes it suitable for scanning microfilms as well as for any other scanning purpose, and it handles even thick, rigid media. It is designed to handle CAD output, GIS and graphics. It is capable of scanning and printing both color and black and white images. The printer is of thermal inkjet type. It can manage widths of up to 42 inches and media as long as 50 feet.
Epson Stylus DX4800 is another all-in-one color printer, scanner and copier. It can give a resolution of up to 5760×1440 optimized dpi on qualified media. It is a fast printer capable of producing as many as 20 pages per minute. The scanning area is 216mm x 297mm. The printing width is also not very high, but the quality is excellent. The scanner has a maximum resolution of 1200dpi and a scanning speed of 30msec per line at this resolution. At lower resolutions of 600dpi and 300dpi, it gives better speeds of 15msec per line and 10msec per line, respectively.

Being flexible in business is an essential factor these days. The wireless solution, a cost-effective and secure technology, allows for building mobility and versatility.
Wireless technology is the same as the technology used in a mobile phone. It uses radio waves to carry data from one point to another. However, one disadvantage with the wireless is that the user must be in the access range. Wireless LAN uses a radio communications device called an access point to connect to the network computers. Access points are small and lightweight, with an antenna attached to send data back and forth over the airwaves.
Wireless networks are usually inexpensive and easy to maintain. Wireless networks eliminate the cost of setting up a wired network, which typically means running Cat-5 cable through the ceiling and walls of the office to each workstation or computer. It is also cost effective and saves the time required for the cable installation. One major advantage is that shifting is easy with a wireless network.
Some of the major advantages of wireless networks are increased productivity, security, easy set up, faster access, efficient collaboration, and industry solutions provided by the companies.
Since wireless network provides convenient access to local network resources and Internet connections, the laptop or the notebook computer can be taken anywhere inside or outside the office, increasing productivity.
It is important to understand that the security level in wireless network technology is the same as the type of security existing on wired networks in conjunction with existing network security technology.
Wireless network provides quick access to the network server. Also, it is easier to share files or exchange e-mails with the team on-site or off-site. It makes it easier to connect to the company intranet.
For a wireless network connection, the user needs a wireless router, Wi-Fi ready computers and LAN capability or a wireless add-in card. Wireless laptops can be used from a broad range of locations like cafes hotels, and airports. These places would have a “hotspot” that can be detected by the wireless laptop. Hotspots are usually free or fee based.
While using wireless laptops in public places, it is suggested to turn off file sharing and avoid sending or receiving sensitive email or personal data. Users should activate a firewall if possible. Always use VPN to connect to work or school from public places.
