Iconia tablet computer on April 20th 2011

Acer is all set to introduce its Iconia tablet computer on April 20th. Acer Iconia, which was showcased during Mobile World Congress, 2011 in Barcelona, has been touted as the most powerful tablet computers of these times. April 20th will notice the launch of first ever dual core processor based, Nvidia Tegra powered tablet computer by Acer.

Iconia is the first ever tablet computer to feature a dual core processor along with a Nvidia Tegra graphics engine. It will be available in a bigger 10.1 inch form factor and a smaller seven inch form factor as well.

Iconia will also feature a 512 MB of RAM for seven inch version and 1GB for the 10.1 inch. Whereas the on board storage, which also doubles up as ROM, is 8GB for the 7 inch and 32 GB for 10.1 inch tablet version.

Based on Google’s latest tablet PC operating system, the Android Honeycomb 3.0, both the tablet computers will come with a custom user interface optimised for the tablets size.

As of now, Acer has plans to launch these tablets in UK first followed with other parts of the world. Priced at GBP 299.99 (Rs 21500) and 449.99 (Rs 32,000) respectively, these are available for pre order on popular shopping stores such as Amazon.

Although these tablet computers are expect to be available in India sooner but people here can buy these from websites such as the Shopyourworld.com and Ebay.in.

What to do when installing Additional Drivers on the print server doesn't work

For some printer (actually print device) models, the manufacturer does not package the drivers so that they can be installed as Additional Drivers on a print server. This is the case for many of the less expensive bubble jet, inkjet and multi-function (e.g. scanner/fax/printer) models. The manufacturers deem these to be "personal" printers for use only on the computer to which they are physically connected (parallel, USB or serial port). The manufacturer often says that printing over the network is "not supported" for these models.

If you attempt to install the drivers for these models as Additional Drivers (see for example Install Additional Driver on older OS), you will get some kind of an error or a request for the driver that can not be satisfied no matter what you do.

Unfortunately, there are some models that can not be used over the network because the print device and printer driver have to be in bi-directional communication throughout the printing process. The manufacturer's documentation does not always make this requirement apparent, although there may be FAQs or other documents on the manufacturer's web site that state this.

Except for those models discussed in the previous paragraph, you can bypass this problem by adding the printer as a local printer on the client computer and associating the printer with a network printer port (i.e. re-direct it to the printer share on the print server). No harm will be done by trying this approach if it doesn't work, so it's usually worth a try.

Here's tips trick computer how to install a printer locally and re-direct it to a network printer port. These instructions are written for Windows XP This technique does work with Windows Vista, 2008, 2003, 2000, and Windows 98 (they may work with Windows 95 and ME also), but the dialogs are a bit different, so you may have to read between the lines.

Follow through the rest of the Add Printer wizard; when you get to the Name Your Printer panel, either accept the default, or key the name you want this printer to be known by on this computer.

Installing Additional Drivers on an older version of Windows

When you create a network printer, and the printer is shared from a Windows operating system in the NT family (e.g. Windows NT 4, 2000, XP), the printer driver can be automatically installed on the client from the print server. This is part of the feature called Point and Print. In many cases, the operating system version of the client computer is not the same as that of the print server hosting the printer. In these cases, the printer driver for the client operating system must be added to the print server as a Additional Driver.

The dialog for adding Additional Drivers this has a fixed idea about what other operating systems exist. So, if your client is Windows XP and the print server is NT 4.0, you can't add an Additional Drivers for a printer for your client using the dialog on the Windows NT 4.0 print server. However, you can install Additional Drivers for Windows XP clients on the Windows NT 4.0 or Windows 2000 print server from a Windows XP computer.

The same applies to installing Additional Drivers for Windows 2000 clients on a Windows NT 4.0 print server.

Note that it doesn't matter what edition of the various operating systems are on either the client or server (e.g. the client could be Windows 2000 Server and the server could be Windows NT 4.0 Workstation).

Basically, what you do is, on a client workstation that has the "new" OS, temporarily add a local printer on a convenient port (e.g. lpt1) and install the Windows 2000 or XP printer driver. Then you connect to the Printers and Faxes (or Printers) folder on the print server from that same client and install the just installed driver as an Additional Driver.

Here's the details. These instructions are for adding a Windows XP printer driver to Windows NT 4 print server. If the client is Windows 2000 or the print server is Windows 2000, the actual dialogs may be slightly different, but the process is essentially the same.

Logon at a client computer with a user account that has administrative rights and permissions on the print server computer.

Click Start, Printers and Faxes

Right click in an empty space in the right pane and select Add Printer

Click Next

Select the Local Printer… radio button, remove the check mark from Automatically detect and install my Plug and Play printer; click Next

Leave the LPT1: port selected; click Next. You will be adding the printer as if the print device is on the local computer’s parallel port, then deleting the printer later. This is just a way to get the XP driver installed, which is a pre-requisite to adding it as an Additional Driver on the server.

(#) If you are going to use the printer driver delivered with Windows XP, select the appropriate make and model. If you have downloaded a printer driver from a web site or have the driver on a floppy or CD, click Have Disk, Browse and navigate to wherever the driver is. Depending on how the driver is packaged, you may get a list of several printer models; in that case, select the appropriate printer model.

Follow through to the end of the Add Printer wizard (don't share the printer and don't ask for a test print)

Delete the local printer you just added; the printer driver is now installed and will NOT be deleted when you delete the local printer

Click Start, Run

Key \\printservername and press Enter

Scroll down in the left pane and click Printers and Faxes in the Windows Explorer window that opens

Right click on the printer you want to add the Additional Drivers for and select Properties

If you get told that a suitable driver has not been installed on your computer for this printer, click Yes and navigate to the same folder you used in step (#). If there are multiple printer models in the list, select the same you used in step (#)

Select the Sharing tab

Select the Shared radio button

Click the Additional Drivers button

Add a check mark to the Windows 2000 or XP item in the list; click OK

If you get a dialog box asking you to insert disks, click the Browse button and navigate to the same folder you specified in step 7; click OK

If you get a message box saying that “… the operation could not be completed…”. Click OK to clear the message box. Go back to step . For some unknown reason, this process sometimes fails the first time, but succeeds on the second attempt.

Image Files

Introduction to Image Files

The format of an image to be used on the Web should be a file type that is "cross-platform" which means that several types of operating systems can use that file type. Platforms are operating systems and system configurations such as a Macintosh running OS X on the G4 with dual processors, a PC running Windows XP, or another computer running the Linux operating system. Your images will need to be in a format that all of the computers operating on the Web can use. Popular file formats for Web use are the GIF and JPEG file formats. All graphical browsers support GIF and JPEG file formats. PNG file formats can only be recognized by some of the graphical browsers but not all of them.
TRANSPARENCY. Transparency is a term used to indicate a GIF89a format file in which a selected color is "taken out" of the graphic file when displayed, so that the browser background shows through the image making the image appear to "float" on the screen. JPEG files do not support transparency nor do GIF87a images.

Image Software

Creating and manipulating images requires drawing or graphics programs and tools. Paint Shop Pro, Adobe Photoshop and Adobe Illustrator are used by Web designers.
Windows users can use Paint Shop Pro, Adobe PhotoShop, CorelDraw and other graphics programs.
Macintosh users: Adobe PhotoShop is available for the Macintosh computer and Quark Express is another publishing and photo editing program for the Mac.
Unix platform developers can use the program called xv developed by John Bradley. This program handles the file formats of GIF, PM, PBM, XBM, RAS, JPG, and TIF and translates them into other file formats (the same as listed, plus PS).
