2. On Epson’s Receipt Printer do right click then select Printing Preferences
3. Select Tab Printer Settings
4. On True Type Font Substitution choose Substitute options
5. Click Advanced Setting to configure font substitution, or simply choose substitute all

Suatu hari di sebuah desa di bali,
seorang yg kaya raya mngumumkan akan membeli monyet dgn harga Rp.100rb per ekornya.
Para penduduk desa yang menyadari bahwa banyak monyet disekitar desa pun mulai masuk hutan dan menangkapinya.

Si orang kaya membeli ribuan ekor monyet dgn hrg 100rb rupiah, krnnya monyet semakin sulit dicari, penduduk desa pun menghentikan usaha menangkapi monyet.
Maka si orang kaya pun sekali lagi mengumumkan akan membeli monyet dengan harga 200rb rupiah per ekor. Tentu saja hal ini memberi semangat baru bagi penduduk desa untuk mulai menangkapi monyet lagi. Tak berapa lama, jumlah monyet pun semakin sedikit dan semakin sulit dicari dan penduduk pun kembali bertani. Hrg monyet pun merambat naik hingga 250rb namun monyet sdh sangat sulit dicari..

Sekali lagi si orang kaya mengumumkan akan membeli monyet dengan harga 500rb rupiah per ekor..!

Namun, karena si orang kaya harus pergi ke kota kareba urusan bisnis, asisten-nya akan menggantikannya atas namanya. Dgn tiada kehadiran si orang kaya, si asisten pun berkata pada penduduk desa: “Lihatlah monyet2 yang ada di kurungan besar yang dikumpulkan oleh si orang kaya itu. Saya akan menjual monyet2 itu kepada kalian dengan harga 350rb per ekor dan saat si orang kaya kembali, kalian bisa menjualnya kembali ke si orang kaya dengan harga 500rb rupiah! Bagaimana?”

Akhirnya, penduduk desa pun mengumpulkan uang simpanan mereka dan membeli semua monyet yang ada di kurungan.

Namun… kemudian, mereka tak pernah lagi melihat si orang kaya maupun si asisten..!

Apple iPad

All of the built-in apps on iPad were designed from the ground up to take advantage of the large Multi-Touch screen. And they work in any orientation. So you can do things with these apps that you can’t do on any other device.

Safari

The large Multi-Touch screen on iPad lets you see web pages as they were meant to be seen — one page at a time. With vibrant color and sharp text. So whether you’re looking at a page in portrait or landscape, you can see everything at a size that’s actually readable. And with iPad, navigating the web has never been easier or more intuitive. Because you use the most natural pointing device there is: your finger. Scroll through a page just by flicking your finger up or down on the screen. Or pinch to zoom in or out on a photo. There’s also a thumbnail view that shows all your open pages in a grid, to let you quickly move from one page to the next.

Mail

See and touch your email in ways you never could before. In landscape, you get a split-screen view showing both an opened email and the messages in your inbox. To see the opened email by itself, turn iPad to portrait, and the email automatically rotates and fills the screen. No matter which orientation you use, you can scroll through your mail, compose a new email using the large, onscreen keyboard, or delete messages with nothing more than a tap and a flick. If someone emails you a photo, you can see it right in the message. You can also save the photos in an email directly to the built-in Photos app. And iPad works with all the most popular email providers, including MobileMe, Yahoo! Mail, Gmail, Hotmail, and AOL.

Photos

With its crisp, vibrant display and unique software features, iPad is an extraordinary way to enjoy and share your photos. For example, the Photos app displays the photos in an album as though they were in a stack. Just tap the stack, and the whole album opens up. From there, you can flip through your pictures, zoom in or out, or watch a slideshow. You can even use your iPad as a beautiful digital photo frame while it’s is docked or charging. And there are lots of ways to import photos: You can sync them from your computer, download them from an email, or import them directly from your camera using the optional Camera Connection Kit.

Video

The large, high-resolution screen makes iPad perfect for watching any kind of video: from HD movies and TV shows to podcasts and music videos. Switch between widescreen and full screen with a double-tap. Because iPad is essentially one big screen, with no distracting keypad or buttons, you feel completely immersed in whatever you’re watching.

YouTube

The YouTube app organizes videos so they’re easy to see and navigate. To watch one, just tap it. When you’re watching in landscape, the video automatically plays in full screen. And with its high-resolution display, iPad makes the latest HD YouTube videos look positively amazing.

iPod

With the iPod app, all your music is literally at your fingertips. Browse by album, song, artist, or genre with a simple flick. To play a song, just tap it. iPad even displays album art at full size. Listen to your music with the powerful built-in speaker or with wired or Bluetooth wireless headphones.

iTunes

A tap of the iTunes store icon lets you browse and buy music, TV shows, and podcasts — or buy and rent movies — wirelessly, right from your iPad. Choose from thousands of movies and TV shows (in both standard and high definition), along with thousands of podcasts and millions of songs. Preview songs before you buy them. Or just sync iPad with the content you already have in your iTunes library on your Mac or PC.

App Store

iPad runs almost 140,000 apps from the App Store. Everything from games to business apps and more. And new apps designed specially for iPad are highlighted, so you can easily find the ones that take full advantage of its features. Just tap the App Store icon on the screen to browse, buy, and download apps wirelessly, right to the iPad.

iBooks

The iBooks app is a great new way to read and buy books.* Download the free app from the App Store and buy everything from classics to best sellers from the built-in iBookstore. Once you’ve bought a book, it’s displayed on your Bookshelf. Just tap it to start reading. The high-resolution, LED-backlit screen displays everything in sharp, rich color, so it’s easy to read, even in low light.

Maps

See more of the world with high-resolution satellite and street view images. Even see topography with the new terrain view. You can also search for a nearby business type (“Restaurant,” for example), then tap the business to see the route and directions from your current location.

Notes

With its expansive display and large, onscreen keyboard, iPad makes jotting down notes easy. In landscape view, you see not only a note-taking page but a list of all your notes. iPad even circles the current note in red, so you can see where you are at a glance.

Calendar

iPad makes it easy to stay on schedule by displaying day, week, month, or list views of your calendar. You can see an overview of a whole month or the details of a single day. iPad even shows multiple calendars at once, so you can manage work and family schedules at the same time.

Contacts

The Contacts app on iPad makes finding names, numbers, and other important information quicker and easier than ever before. A new view lets you see both your complete contacts list and a single contact simultaneously. Need directions? Tap an address inside a contact and iPad automatically opens Maps.

Home Screen

The Home Screen gives you one-tap access to everything on iPad. You can customize your Home Screen by adding your favorite apps and websites or using your own photos as the background. And you can move apps around to arrange them in any order you want.

Spotlight Search

Spotlight Search allows you to search across iPad and all of its built-in apps, including Mail, Contacts, Calendar, iPod, and Notes. It even searches apps you’ve downloaded from the App Store. So no matter what you’re looking for, it’s never more than a few taps away.

In one TV programme I saw an air compressed driven motor to propel a bike. This technology offers new alternative cleaner energy for transportation. It’s was Jem who has Big Idea…An Air-Propelled Bike.

Eco-Engineers Dick Strawbridge And Jem Stansfield Aim To Fulfil A Dream. But First They Must Test The Potential Danger Of Compressed Gas So They Build A Contraption From A Pair Of Giant Bolt Cutters.

Jem Stansfield Eco-Engineer Puts A “Rocket Up His Bottom” In The Form Of An Air-Powered Bike. All In The Aid Of Science.

On above picture, Jem took carbon-fiber air tanks that are usually used by firefighters as part of their breathing equipment and connected them to two rotary air engines that drive the rear wheel. One of the benefits of using compressed air over batteries is that you can recharge in a few seconds. Of course, the compressor works on electricity, so that’s not always a clean power source. But even if your local utility uses coal, if you recharge at night or off peak, chances are you are using power that would be wasted otherwise because coal power plants take too long to shut down and restart, so they are often kept producing at night. But it is with a clean electricity source for the compressor that the air-powered motorcycle becomes a truly green ride. (www.treehugger.com)

Specifications for Jem’s Air-Powered Motorcycle
Top speed is 18 mph (29 kph), range is 7 miles (11.2 kilometers) between compressed air fill ups.

I wonder, when will air-propelled bike being mass produced.
