Description
Technical field
The utility model relates to printer accessory, is specifically related to a kind of intranet and extranet physical isolation print system.
Background technology
Current all trades and professions are all in a large amount of use computer technologies.Industrial and mining enterprises, public institution's daily management mostly depend on computer technology.Along with the development of Internet technology.Computer Applied Technology based on the Internet has had significant progress.Simultaneous computer virus and network hacker are also spreading unchecked by network technology, constrain the development of computer networking technology.If a computer be operated on a local area network (LAN) (Intranet) is subject to the attack of virus and paralyses, extremely serious consequence can be caused.The special industrial production enterprise as some continuous operations, some important public institutions (such as a subbranch of bank), its consequence cannot be imagined especially, the attack that database server can be caused to be subject to virus and hacker makes critical data lose or leaks, and brings very large loss.Therefore, the isolation technology therefore between the data of internal network and external network (or the Internet) just seems particular importance.
To industrial and mining enterprises, public institution, often have a part computer to be Intranet computer, a part of computer is outer net computer.Want to realize Intranet computerized print, need at a part of printing equipment of interior online configuration.Want to realize outer net to print, need a part of printing equipment of online configuration outside.These printing equipments comprise pin: formula printer, ink-jet printer, laser printer, scanner etc., these printing equipments are connected with Intra-Network switch by printing server, realize the network printing of inner net computer, or be connected with outer network switch by printing server, realize the network printing of outer net computer.Impact printer is by piece pin of 24 in printhead impact carbon paper, thus forms font, and in use, user can select multi-joint paper according to demand, and general conventional multi-joint paper has 2,3,4 paper, wherein also has the printer paper of use 6.The disposable printing of multi-joint paper completes only has impact printer to complete fast, and ink-jet printer, laser printer cannot realize multi-joint paper and print.Ink-jet printer grows up after impact printer, adopts the working method of non-strike.Relatively outstanding advantage have volume little, simple to operation, print noise low, use during special paper and can get picture compared favourably with photo etc.The shortcoming of ink-jet printer be consumptive material costly, without multilayer manifolding ability, and nozzle easily blocks.Laser printing technology appears at six the seventies the earliest.Initial laser printer adopts the electronic laser pipe being filled with helium-neon body as generating laser, and volume is larger.Along with laser printing technology is ripe rapidly, numerous technical staff, in the technical foundation of Xerox, in conjunction with laser technology and computer technology, designs semiconductor laser printer in succession.Laser printer is relative to impact printer, and not only print quality is good, output speed fast, noise is extremely low, and print load amount is high, therefore obtains very soon and applies.But the initial stage input cost of laser printer is large, consumptive material price also higher, can not multilayer manifolding, and also higher to the requirement of print media.Therefore, to industrial and mining enterprises, public institution, the printing of its document, photo printing, document output, industry mapping, typographical printing etc. need dissimilar in a large number, the printing equipment of different paper size, if Intranet, outer net all arrange some printing equipments separately, cost is very high.Particularly when the existing some Intranet computers of an office or several office, when having some outer net computers again, need to configure some printers in each office, adapt to the difference printing demand of Intranet, external user, cost is very high, and printer service efficiency is also low.And limited space in office, cabling is very complicated, also brings much inconvenience.If Intranet, outer net are connected, be connected with these printers simultaneously, there will be again data and use dangerous, easily suffer the problem of virus and assault.
