2.4 Identify procedures for loading/adding and configuring application device drivers, and the necessary software for certain devices.

Windows 9x Plug and Play and Windows 2000

Plug and Play is an independent set of computer architecture specifications that hardware manufacturers use to produce computer devices that can be configured with no user intervention. When you install a device, you do not need to know its Plug and Play requirements, because they will be set automatically.

You can install hot-pluggable Plug and Play–compliant devices simply by plugging in the device. For other devices, such as Plug and Play Industry Standard Architecture (ISA) cards, you must plug in or install a device while the computer is off and then turn the computer back on to initialize the device.

Windows 98 detects the presence of a Plug and Play–compliant device. This is known as enumerating the device. After enumeration, the device driver can be configured and then loaded dynamically, requiring little or no user input. Certain buses (for example, peripheral component interconnect [PCI] and Universal Serial Bus [USB]) are also automatically enumerated; these buses take full advantage of Plug and Play capability.

You can add some Plug and Play functionality by adding Plug and Play–compliant devices on legacy computers. Therefore, it is best to add Plug and Play–compliant devices on legacy computers rather than adding non–Plug and Play devices. To be able to use all Plug and Play features, however, your system must also include one of the following:

An Advanced Configuration and Power Interface (ACPI) BIOS.
A Plug and Play BIOS (for Plug and Play devices on the system board).
The Plug and Play–compliant hardware devices (including buses).
Identify the procedures for installing and launching typical Windows and non-Windows applications.

Windows 9x simplifies installing Win32-based applications by providing an Add/Remove Programs option in Control Panel. When you install an application using this option, Windows 98 does the following:

Searches specified drives for files named Install or Setup.
If an application setup file uses a name other than Install or Setup, you can start setup by double-clicking the application setup file’s icon in My Computer.
Adds to the registry such information about the application as which parameters to use to run the application and which files to delete when removing the application from the computer.
To install an MS-DOS-based application by running its Setup.exe file. When you install the application, Windows 9x copies information about the application from Apps.inf to the application’s program information file (PIF). If the application was installed under an earlier version of Windows, Setup automatically moves its settings to the new Apps.inf. If there is no information about the application in Apps.inf, Windows 9x uses default settings instead, or you can manually set the properties.

Procedures for set up and configuring Windows printing subsystem.

Install Printers in Windows 9x

Plug and Play

For Plug and Play–compliant printers, all you need to do is plug the printer cable into a port, make sure the printer is turned on, and start Windows 9x. The printer reports its device ID to Windows 9x, which searches INF files to find the ID that matches the values reported by the printer. If an exact match is found, Windows 9x automatically installs the correct printer support. If an exact match is not found, but a compatible printer driver is found, Windows 9x displays a dialog box showing that the printer was found and that a compatible printer driver is available. You can then provide a disk containing a Windows 9x printer driver that is an exact match or ask Windows 9x to install the compatible driver it has found.

Add Printer Wizard

The Add Printer Wizard leads you though the process of setting up and configuring a printer. The only difference between installing a network printer and a local printer with the Add Printer Wizard is that you must specify the path to the network printer or browse to find its network location.

Remote Installation Using Point and Print

Point and Print allows users to install a printer over a network by providing printer driver information. Users can point to the printer, by using the Add Printer Wizard and browsing to or typing the path of the print server. By typing the path of the print server in the Run dialog box on the Start menu. By opening the print server’s print queue using Network Neighborhood or Windows Explorer.

Vendors Disk

Yon can also set up printers using the drivers supplied with the set up disk, provided with the printer or downloaded from the vendors web site.

Setting Default printer

Right-click the icon for the printer you want to use as the default printer, and then click Set As Default. If there is a check mark next to this command, the printer is set as the default printer.

Installing/Spool setting

Open printers folder, right-click a printer icon, and then click Properties
Click the Details tab, and then click Spool Settings
Select Spool print jobs so program finishes printing faster, and then click one of the following options
Click Start printing after last page is spooled if you want the return-to-application time to be faster. This requires more disk space and increases the total print time. The second rendering does not start until the entire file is written to the EMF file, decreasing the amount of work performed on the computer as you print, but increasing the disk space, because the entire file has to be written before the second rendering starts.
Click Start Printing After Page Is Spooled if you want the second rendering to take place simultaneously with the writing of the EMF file. This reduces the total print time and disk space required, but it increases the return-to-application time.
Network printing (with help of LAN admin.)

The following are considerations for printing on a network:

To share a printer on either Microsoft or NetWare networks, the print server must be running a 32-bit, protected-mode client, and file and printer sharing services must be enabled.
With Point and Print, users can install a network printer if the print server has been configured with the correct printer drivers. You need to designate which network servers will function as print servers and configure them to store Point and Print.
