Nancy, a professional architect was in need of a printer to take a print out of drawings of the buildings designed by her. She was aware of the tremendous improvements that have taken place in printing technology. There was a time when printing was restricted to A3 size paper. Now, large format printer is capable of printing in size running to more than five to six feet. At this stage the technicians of HP DesignJet plotter repairs introduced her to vector printers also called as plotters. They explained to her the relevance of the plotter to her work. This helped Nancy to make the best choice of printer.
Types of plotters:
Plotters are generally classified into two namely electrostatic plotter and cutting plotter. The electrostatic plotter uses ink jet printing technology, and such plotters are called as jet plotters. On the other hand, the cutting plotters use computer software program and a specially designed pen. However, modern cutting plotters use varieties of die cutting tools, and these plotters are extensively used in paper craft and such other works. The technicians which offer the services of HP DesignJet plotter repairs must have thorough knowledge of all such exclusive varieties of plotters.
As already said, the technology adopted in a plotter is quite different from the technology used in other printers and Xerox machines. Although there are areas of similarities, there are also areas, which require in-depth understanding of the working of the jet plotter and cutting plotter. It is for this reason the manufacturers insist that the technicians should undergo extensive training in HP DesignJet plotter repairs services. In fact, the manufacturers even conduct periodical refresher courses, which help the technicians to update their knowledge about the changes in the technology introduced in the plotters.
The working of plotter:
The plotters are extensively used for printing images, graphics, labels, maps and such other data. As far as the working of a plotter is concerned, the inkjet plotter sprays ink onto the paper similar to inkjet printer. On the other hand, pen plotter marks the graph with the help of specially designed pen or pencil. On the other hand, electrostatic plotter gently cuts or embosses the paper to form the desired image. Like any other printer, even the plotters need proper maintenance, which helps in proper functioning of the plotters. It is for this reason you must entrust the task of maintenance of plotter to specialized professionals who excel in HP DesignJet plotter repairs.
The need for maintenance:
The earlier version of plotters was integrated with a computer-aided design system. However, modern plotters have undergone tremendous transformations. Now, manufacturers have introduced wide body inkjet and pen plotters. Any flaw in the plotter may either slow down the working of the plotter, or it may even affect the quality of prints. This problem can be effectively addressed by availing the services of technicians who offer HP DesignJet repair services.
The type of printer plotter to be used for taking printouts of any given matter depends on the type of graphic. For example, vector graphics use line or varieties of shapes or curves. For such graphics, pen or electrostatic plotter is an ideal tool. In other cases, bitmap jet plotter can be an ideal choice. The technician who offers HP DesignJet service will be able to suggest the type of plotter that is ideal for your organization. Visit Printer repairs
There has been an increase on cyber-attacks on vital infrastructures and this has become a pandemic for organizations and governments all around the world. Metropolitan traffic control systems, power generations facilities, factories and even water treatment systems have become some of the key targets of cyber attackers. Furthermore, there have been reports of a wide array of data thefts, network breaches and even denial of service operations. The level of vulnerability in these organizations vary from standard issues such as systems with default only password to software bugs and configurations problems. As soon as the attacker runs a program that is able to access the controller, then there is a high chance of a cyber-attack. All these are potential threats to the SCADA networks.
Understanding SCADA and the SCADA systems
Vital infrastructure facilities such as oil, electricity, waste and gas depend on electrical, hydraulic, mechanical and other kinds of equipment. This equipment is managed by computer systems that are called controllers and sensors. The SCADA systems are also linked with the management systems to form a network that leverage ICS and SCADA solutions. Both SCADA and ICS allow for efficient data collection and analysis and help in system automation of equipment such as valves, pumps and relays. These systems have many benefits and have led to their wide adoption. Their stability and reliability helps vital infrastructure facilities to use both SCADA and ICS solutions for a very long time.
These networks were made to offer a reliable system management. In most cases, they don’t include mechanisms so as to cope up with the current security threats from both internal and external networks in the IT industry.
Many people believe that the SCADA system and ICS are separated from IT networks. Well, this is very true, but only as far as physical separation is concerned. Many SCADA systems are vulnerable to attacks because of the following reasons
Lack of monitoring
Lack of active network monitoring has played a major role in encouraging cyber-attacks. Without monitoring, it is not easy to identify suspicious activities, detect potential threats and react to the attacks promptly.
The SCADA systems are continually advancing. However, the problem is that with increased advancement, the vulnerability of the systems also increases and this attracts new attacks. Without the right systems in place managing software and firmware updates may not be convenient. However, the updates are still critical for optimum protection.
Lack of knowledge about devices
Devices that are connected to a SCADA system are easy to monitor and control as well as to update. However, not all devices have reporting equalities, meaning that there is little knowledge regarding network connected devices.
Not understanding traffic
Employees need to know the kind of traffic that is running through their networks. Only then they can decide the best approach to take to respond to network threats. With the technological advancements in data analysis, one can get a vivid picture of the information collected from traffic monitoring and use such Intel for actionable intelligence.
