But now, not just paperwork and correspondence that a lot depends on the printer, but it almost covers all areas - including for the type of graphic work. And whose name this printer, very rapid development. The first can only print to a maximum size of A3 +, now there's a printer that can print width of 4 meters, even labih, with unlimited length.

But that we will discuss here, just standard office printers and personal, that inkjet printers, which use only range to print documents and graphics in a maximum size of A3 +.

Tips on Caring for Caring BenarTips Printer That Printer That BenarKarena this printer can be very important, if more is needed for sure, so we hope that this stuff is always in top condition. Because if we again need to use but the printer was down, both in quality and technical, then woe to us. Therefore, technology object is not possible we can fix itself if damaged, except that only the disruption in terms of quality - for example, striped prints, or color is not flat, it can be overcome by performing mechanical repairs, which can be done with the help of software.

To avoid having problems when the printer we need, and also so that more durable printers, and print quality remains excellent, regular maintenance is necessary and painstaking. Well, here are tips that you can use to keep your printer longevity, relatively safe from the problem, and the results are always excellent.

How to care for the right printer:

Tips on Caring for Caring Printer Printer That BenarTips BenarYang The main thing is keeping the printer. Close all the way in and out of paper so that no objects in there. Both dust and other potentially damaging objects such as a clip or other object. Remove dust with a brush or blown, are for the wheels rubber or plastic, wipe with a damp cloth or a cotton bud soaked in, so that dust is lifted.

Because inkjet ink could freeze and obstruct the smooth ink when printing, the printer should be used every day, at least one sheet of paper.

When printing in large quantities, rest your printer after printing 15 pages each, about 5 minutes, so that no mechanical overheating causing premature wear.

Tips on Caring for Caring BenarTips Printer That Printer That BenarAgar paper is not sticky, so it retracts when printing in large quantities, before being put into the entry point of paper, the paper should be thoroughly shaken, that is by bend-bend (but not until it broke).

Do not put too much paper in the amount of the entry point into the paper, so as not to interfere with the mechanism of action wheel puller paper.

Use paper with a thickness of standard sizes or as recommended. Because not all printers can accept a paper that is too thick or too thin.

Each time a new turn on the printer, you should not directly be used. Allow the printer to warm up sufficiently, or if a new reset improperly discharged dead due to power failure and so on.

After use, turn off the printer through the habit of power. But before turning off, make sure the printer is completely in a state of the cartridge stops working and has returned to its original position.

Do the cleaning process if needed. For when too often make the process of cleaning, head cartridge will quickly wear out, so it will reduce print quality.

Tips on Caring for Caring BenarTips Printer That Printer That BenarMenggunakan original ink is the most appropriate choice, as long as you can bear with the price is not cheap. So, if want to print black and white documents, we recommend using the option to print only in black and white, not full color, because it will spend another color ink.

If you use the ink refill, you should do the refilling ink refilling place that is good quality. However, cartridge refilling has limits. So, if you've refilled a few times, usually cartridge performance will decrease, which means also reduces print quality.

If you use the ink infusion, you should not let the ink less than half of the tube.

Tips on Caring for Caring BenarTips Printer That Printer That BenarJika printer has a problem, you should not knowledgeably to fix it yourself. Therefore, the result is not so good but even more damaged. Because the printer is not every day is damaged, you should take it to the service or to where you put ink infusion, if the printer is having problems.

If the print is a daily routine, you should not have only one printer. So that if the printer has a problem, you still have a backup to be able to continue working.

Be careful with the printer parts that seem sensitive to dirt or touch, such as chips, sensors, and others. Because if it objects to the disorder, resulting in poor performance of the printer so.

Place the printer in a shady and dry place. Do not expose to direct sunlight and do not get hit too wet. Because the printer has many components that are susceptible to heat and wet.

Well, so be it. May be useful.

Printer problem, which often occurs in canon printer

I think Canon is a favorite printer, can be said of the favorite because this printer has good print quality, and fast. But maybe there are a lot of issues going on but not as often as other brands "do not say the name brand":-d one of the problems I experienced this morning on the printer canon ip 1980 which is when they want ngeprint it says -> "vacuum ink full service contact center "or the ink absorber is full well the problems which service center should be in contact :). Finally I tried googling and found articles that can overcome these problems, the results of googling that ane can to address issues that often arise in canon printer:

1. Blinking, Proofing indicator is flashing when printer is turned on
Usually this disease struck Canon iP1200, IP1300, iP1600, iP1700, i255, Lightweight Solution, this solution means you should do every time you turn on the printer, because this is only temporary. When your printer is disconnected from the power outlet, then it will re-emerge blinking. But there is not no harm in doing this step, if you are not familiar with ways to reset the printer using the software.
Unplug the power cord from your printer.

• Press and hold the Power button, while you replace the power cord. The power indicator lights appear yellow. Release the power button when you have finished installing the power cable. Then press the power button again to turn on your printer.
  Ensure your printer is not blinking anymore. But when your printer is disconnected from the power outlet, then blinking will appear, and you just repeat the above steps.

Software Solutions, you can overcome this by using a blinking disease GeneralTool software specifically for iP 1300 and iP 1700. By using this software, blinking usually be resolved permanently, meaning you do not need to be repeated as the mild solution above.

2. Blinking, blinking when the ink runs out, or when the contents of the ink finishes

Usually this disease struck Canon iP 1880 printer, and occurs when the ink runs out or when you are done filling ink. Or even the ink is not depleted, but blinking is often struck iP 1880. One solution:

• Press and hold the RESUME button for about 1 to 2 minutes

Google+ is now accepting applicants to join the Youth

Google+ is now accepting enrollees aged 13 and older adolescents in most countries, providing a large demographic of social network as a target as it seeks to increase the number of users has now reached 90 million users.

Twitter and Facebook also has determined the age of 13 years as the minimum age limit of users who can join their social networks, so in the sense that Google is also following in their footsteps.

While most teens around the world can be joined at the age of 13 years, Google set a minimum age for new members at the age of 14 years in Spain and South Korea, and 16 years in the Netherlands.

"Teenagers and young adults are most active Internet users on the planet," said Bradley Horowitz, Google's vice president of product management for Google. "And surprise, surprise: They are also people who enjoy spending time with friends and family. Based on these two items, and it is clear that adolescents will increasingly connect online .. "

Google cares enough to make sure teens share what they want to share in the right context, in a bid to persistent oversharing on social networking among teens connections that may be more than acquaintances than actual friends.

To wit, when teens share something outside the circle (circle) they have created, Google + will membarikan notification before they post.

For secure information sharing manjaga among adolescents, Google has made it so that only they (teenagers) are there in the circle can contact each other through chat sessions.

There are other places where control of discretionary share more uncertain. For example, if a stranger outside the circle to join in a teen's Hangout video chat session is in progress, Google + will remove it for a while during the teenage aliens were active in the session.

Google also announced several new pages that Google + teens might like, including the 106 and Park, Ashley Tisdale, Cody Simpson Rushm Big Time, Teen Vogue and Glee.

Google welcomed the teens into social networking two days after the company announced it would support a nickname (nickname) and examined several pseudonyms.

Dasar dasar Jaringan Komputer

Dasar Jaringan Komputer

Jaringan komputer adalah sebuah sistem yang terdiri atas komputer dan perangkat jaringan lainnya yang bekerja bersama-sama untuk mencapai suatu tujuan yang sama. Tujuan dari jaringan computer adalah:

* Membagi sumber daya: contohnya berbagi pemakaian printer, CPU, memori, harddisk.

* Komunikasi: contohnya surat elektronik, instant messaging, chatting

* Akses informasi: contohnya web browsing

Agar dapat mencapai tujuan yang sama, setiap bagian dari jaringan komputer meminta dan memberikan layanan (service). Pihak yang meminta layanan disebut klien (client) dan yang memberikan layanan disebut pelayan (server). Arsitektur ini disebut dengan sistem client-server, dan digunakan pada hamper seluruh aplikasi jaringan komputer.

Sejak memasyarakatnya Internet dan dipasarkannya sistem operasi Windows95 oleh Microsoft, menghubungkan beberapa komputer baik komputer pribadi (PC) maupun server dengan sebuah jaringan dari jenis LAN (Local Area Network) sampai WAN (Wide Area Network) menjadi sebuah hal yang biasa. Demikian pula dengan konsep "downsizing" maupun "lightsizing" yang bertujuan menekan anggaran belanja khususnya peralatan komputer, maka sebuah jaringan merupakan satu hal yang sangat diperlukan. Dalam makalah ini akan dibahas sebagian komponen yang diperlukan untuk membuat sebuah jaringan komputer.

Sejarah Jaringan

Konsep jaringan komputer lahir pada tahun 1940-an di Amerika dari sebuah proyek pengembangan komputer MODEL I di laboratorium Bell dan group riset Harvard University yang dipimpin profesor H. Aiken. Pada mulanya proyek tersebut hanyalah ingin memanfaatkan sebuah perangkat komputer yang harus dipakai bersama. Untuk mengerjakan beberapa proses tanpa banyak membuang waktu kosong dibuatlah proses beruntun (Batch Processing), sehingga beberapa program bisa dijalankan dalam sebuah komputer dengan dengan kaidah antrian.

Ditahun 1950-an ketika jenis komputer mulai membesar sampai terciptanya super komputer, maka sebuah komputer mesti melayani beberapa terminal. (Lihat Gambar 1.) Untuk itu ditemukan konsep distribusi proses berdasarkan waktu yang dikenal dengan nama TSS (Time Sharing System), maka untuk pertama kali bentuk jaringan (network) komputer diaplikasikan. Pada sistem TSS beberapa terminal terhubung secara seri ke sebuah host komputer. Dalam proses TSS mulai nampak perpaduan teknologi komputer dan teknologi telekomunikasi yang pada awalnya berkembang sendiri-sendiri.

Jaringan komputer model TSS.

Memasuki tahun 1970-an, setelah beban pekerjaan bertambah banyak dan harga perangkat komputer besar mulai terasa sangat mahal, maka mulailah digunakan konsep proses distribusi (Distributed Processing). Seperti pada Gambar 2., dalam proses ini beberapa host komputer mengerjakan sebuah pekerjaan besar secara paralel untuk melayani beberapa terminal yang tersambung secara seri disetiap host komputer. Dala proses distribusi sudah mutlak diperlukan perpaduan yang mendalam antara teknologi komputer dan telekomunikasi, karena selain proses yang harus didistribusikan, semua host komputer wajib melayani terminal-terminalnya dalam satu perintah dari komputer pusat.

Jaringan komputer model distributed processing.

Selanjutnya ketika harga-harga komputer kecil sudah mulai menurun dan konsep proses distribusi sudah matang, maka penggunaan komputer dan jaringannya sudah mulai beragam dari mulai menangani proses bersama maupun komunikasi antar komputer (Peer to Peer System) saja tanpa melalui komputer pusat. Untuk itu mulailah berkembang teknologi jaringan lokal yang dikenal dengan sebutan LAN. Demikian pula ketika Internet mulai diperkenalkan, maka sebagian besar LAN yang berdiri sendiri mulai berhubungan dan terbentuklah jaringan raksasa WAN.

Evolusi Jaringan

a. Mainframe pada era 1960-1970 an

Pada tahun 1940-1n komputer adalah suatu alat dengan ukuran besar yang sangat rentan terhadap kesalahan. Pada tahun 1947, ditemukannya transistor semikonduktor membukan banyak kemungkingan untuk membuat komputer dengan ukuran lebih kecil; dan tentunya lebih handal. Pada tahun 1950-an institusi-institusi besar muladi menggunakan komputer-komputer mainframe, dimana dijalankan dengan program-program punched card. Pada akhir tahun 1950-an, Integrated circuit (IC) yang mengembangkan beberapa, dan sekarang jutaan, transistor pada satu semikonduktor yang kecil telah ditemukan. pada tahun 1960-an, mainframe dengan terminal dan IC telah banyak digunakan.

b. LAN (Local Area Network) pada era 1970-1980 an

Pada akhir 1960-1n dan 1970-an komputer-komputer yang lebih kecil dengan sebutan minicomputer telah diciptakan. Walau bagaimana-pun, minikomputer-minikomputer masih dalam ukuran yang sangat besar dibanding dengan standar modern saat ini. Pada tahun 1977, Apple Computer Company memperkenalkan mikrokomputer, dimana dikenal dengan sebutan MAC. Pada tahun 1981 IBM memperkenalkan PC pertamanya. Mac yang user-friendly, IBM PC yang open-archetecture, dan langkah lebih jauh dari proses "micro-minisasi" dari IC membawah penyebaran luas dari PC baik di rumah maupun di kantor-kantor.

Pada masa ini jaringan-jaringan local mulai dibuat dikembangkan dengan berbagai macam teknologi.

c. WAN (Wide Area Network) pada era 1980-1990 an

Pada pertengahan 1980 pengguna PC mulai menggunakan modem untuk berbagi file dengan komputer lain. Hal ini dikenal sebagiai point-to-point, atau komunikasi dial-up. Konsep ini disebar oleh penggunaan komputer yang merupakan pusat dari komunikasi dalam koneksi dial-up. Komputer-komputer ini disebut bulletin boards. Para pengguna akan konek ke bulletin boards, meninggalkan dan mengambil pesan, sebagaimana upload dan download file. Kekurangan dari tipe ini adalah sangat sedikitany komunikasi langgung dan selanjutnya hanya orang-orang tertentu yang tahu mengenai bulletin board. Pembatasan lain dari bulleting board adalah satu modem per satu koneksi. Jika lima orang terhubung secara simultan, hal ini akan memerlukan lima modem terkoneksi ke lima jalur telepon terpisah.

Jumlah orang yang ingin menggunakan sistem ini berkembang, sistem ini selanjutnya tidak dapat meng-handle kebutuhan yang terus meningkat. Sebagai contoh, bayangkan jika 500 orang ingin terhubung dalam waktu yang bersamaan.

d. Internet pada era 1990 an

Dari tahun 1960-an ke tahun 1990-an Departemen Pertahanan Amerika Serikat (DoD) mengembangkan Wide-Area Networks (WANs) yang besar, dapat dihandalkan untuk militer dan alasan-alasan sains. Teknologi ini berbeda dari komunikasi point-to-point yang digunakan dalam bulletin boards. Hal ini memungkinakan beberapa komputer untuk terhubung secara bersamaan melalui beberapa jalur berbeda. Jaringan itu sendiri akan bisa membedakan bagaimana memindahkan data dari komputer satu ke komputer lain. Satu koneksi dapat digunakan untuk berhubungan dengan banyak komputer pada saat yang bersamaan. Jaringan yang diterapka DoD nantinya akan menjadi jaringan yang mendunia pada saat ini yang disebut Internet.

Recently a security researcher Christian Holler system found defects / weaknesses Out-of-bounds Writing in Chrome v8 JavaScript Engine, which means that the system can perform the writing process in place where it should be used to write. This can be exploited by attackers to execute code / program illegally.

This discovery by Christian Holler get from Google's award of $ 1000. Even this weakness in the follow up directly with improvements later in the launch in v8 JavaScript Engine version 3.5.10.24.

If at that 15.0.874.120 stable version of Chrome was released on 10 November, google fix seven flaws in the system, so now Google has released Chrome as well 15.0.874.121 Stable version for the Windows platform, Mac and Linux. This update is an improvement over previous versions of weakness identified as CVE-2011-3900 and includes high-impact defects against unauthorized activity. It is not common in the browser service that directly release the latest version with just a single fix vulnerabilities in JavaScript, but google proved to be very active attention and gave a positive response to weaknesses in browsers.
