EPSON INKJET CARTRIDGES

In an era in the development of printers, as opposed to the laser, inkjet printers are enjoying popularity for many, if not most small businesses and personal users. The two types of printer available use different scientific methods to achieve an almost identical (certainly to the layman) result on the final printed material.
Within the category of inkjet printers there are also fundamental differences between Epson and the other three big worldwide manufacturers (Canon, Hewlett-Packard and Lexmark). These differences are rather interesting to the layman, and absolutely fascinating to the scientifically inclined amongst us, not least because of the space age technology used. If you didn t know already, you may look at your ink cartridge and printer head with some amazement once you realise what goes on inside it.
Of the basic two types of inkjet printer Canon, Lexmark and Hewlett-Packard s development and manufacture use the thermal inkjet method. This involves a cartridge with a series of tiny electrically heated chambers made by a method known as photolithography. To make an image an electric current is passed through the heating elements. These produce steam and the explosion of this forms a bubble which sends a tiny drop of ink onto the paper, whilst at the same time using the escaped steam to refill the chamber from the ink tank known as the reservoir. Pretty clever stuff eh? considering all this is happening in miniscule dimensions.
For this method inks are made from water-soluble pigments or are dye based. . Most commercial and industrial and all Epson inkjet printers use what is called a piezoelectric method, the material for which is contained in an ink filled chamber behind each nozzle rather than the other method of using a heating element. Electricity causes changes in the size or shape of the crystals (the piezoelectric material) which pushes the tiny drop of ink through the nozzle by the generated pressure pulse. The crystals are shaken around and either used in the nozzles or returned to their reservoir by positively or negatively charging each particle.
These two systems lead to an almost identical final product but the piezoelectric method does actually allow for a greater range of colours to be used, producing in general, particularly at the professional level, a better final result.
So you can see from all the above technical waffle that it s really very important to get an Epson inkjet cartridge if you have an Epson printer. The make up of the cartridge is entirely different from those used by the other manufacturers of printers and inks using the thermal inkjet method so they are not in any way compatible with each other.
Epson inkjet cartridges come in many shapes and sizes to suite your printer, whether you just have one at home or you are a professional printer or small business person there will be a cartridge to fit your needs from the seemingly enormous range.

Offshore Outsourcing First Preference is India

India take a top position for offshore software outsourcing across the globe but with the excellent governmental support, China is also on the top way of offshore outsourcing, according to the survey from Gartner.
For Offshoring destination only India has the excellent combination of good economical resources and forceful technology communication. Gartner expect it will carry on to pick up the lion s share of world offshore market spending on Information Technology services, which is expected to sum $50 billion by 2007.
Even though India s governance, Gartner is advising companies looking at offshore software outsourcing to consider various locations around the globe.
India will face competition from China, Mexico, Brazil, Russia and the eastern European countries like Poland, Czech Republic, Hungary but only China comes close in the prospective
to match India in terms of volume and the number of software professionals, said by Gartner.Ian Marriott, survey VP at Gartner, also caution that while the price of labour will
stay a serious issue in the selection of offshore outsourcing location, companies need to do a comprehensive price versus risk equation.
In the survey he said "companies must realize the different types of risks when they choosing world software teams or software outsourcing, and judge each through a more exacting due diligence of the short listed offshore companies."
Gartner is suggest some offshore software development companies, like, Estonia, Lithuania, Mauritius, Belarus, Latvia,
Ukraine, Slovakia and New Zealand but they do not have the enough resources and infrastructure to deliver offshore services on a profitable market.Analyst Forrester survey shows the UK software companies lead the European
outsourcing market on the behind of excellent activity through public sector and economical services and companies. BT Global headed the customer report for deal value after settle a 2.2bn deal with the Defense Ministry.
Reports figures also showed a refuse in the stage of infrastructure offshore outsourcing, past year network outsourcing and telecoms grew eighty percent and accounted for approximately third of all the business transaction.
According to a new survey a high software talents,/i> shortage and inferior physical infrastructure could threaten India s place as the top knowing offshore outsourcing place by 2010.
Labour market pressures could set down India facing a shortage of approximately 500,000 information technology staff reported by McKinsey and Indian information technology NASSCOM.
Jayant Sinha said: "The ability and feature of the workforce require to be enhanced, since only twenty five percent of technical college graduates and ten to fifty percent of general graduates are eligible for service in the offshore outsourcing and BPO market."

The Minimum You Need To Know About Java On Openvms

Roland Hughes manual, The Minimum You Need to Know About Java on OpenVMS, is the second book that builds on his first book, The Minimum You Need to Know to be an OpenVMS Application Developer. Java is an object-oriented programming language that borrows much syntax from C and C++ but has a simpler object model and fewer low-level facilities.
In this second book, Hughes creates and demonstrates the tools you need to make Java a usable language on OpenVMS. The author delivers an in-depth guide to overcoming the problems C/C++ programmers have with Java. He notes that the problems many have with Java are rooted in syntax and where the language came from. Because the creators of Java wanted it to be a pure OOP language, Hughes explains that in Java, most things are classes. Although appearing similar in C and C++, it is not. Java has a unique class called an Array and no defined constructor. This means values can be stored anywhere and in no specific order.
In a carefully crafted and illustrated order, Hughes presents a step-by-step manual to implementing Java for more application development on OpenVMS. He points out that successfully using Java on OpenVMS requires the development of a Free Class Library. Programmers learn how to create a Class Library developed in the OOP language. As well, Hughes shows how to write Java classes using the Java Native Interface (JNI).
As in the previous book, Hughes rewrites the same application (mega-zillionaire application) with each new tool. After developing the application with Java, FMS, and RMS indexed files, he redevelops the application in this book using Java with FMS and RDB. Giving systematic and easy to follow instructions, programmers learn how to build infrastructures while at the same time building the application. Readers are shown how to develop a generic class that will be usable by Indexed Files. Hughes demonstrates how to use JNI to access RMS, FMS, system services, and operating system provided libraries. As well, programmers learn to create an infrastructure MMS Procedure and how to use the supporting classes the procedure creates. Hughes shows how to access RDB by way of the JDBC driver highlighting the importance of SQL. The CD that comes with the book contains the Full Class source.
Well-illustrated examples with detailed analysis, descriptions, and definitions, allow readers to follow the book while working with the server, thereby learning how to implement and operate Java on OpenVMS. Each chapter details troubleshooting tips, error handling tips, as well as providing exercises to enhance understanding of the tools.
With plenty of expertise, the author presents Java with all its advantages and pitfalls while often comparing it to C++. Together with easy to follow instructions, detailed examples, and an informative chapter on the future of IT, I highly recommend the book as an asset to computer programmers and those entering the IT field.
