- Multifunction A3 inkjet printer This 4-in-1 inkjet device boasts business functionality with a cost efficiency to be rivalled. Print up to A3 and use the 50 sheet A4 document feeder (ADF) to make copying and scanning quicker and easier. Access features easily using the 9.3cm colour touchscreen. Inkjet now means business.
The HP Deskjet 2621 is one of those multifunction devices that have come to facilitate the user’s work. So, with just one small printer you can print, copy, scan, and fax any document. It is a technology that also considerably reduces the footprint with all these other devices. Driver Architecture and Design¶. The driver implements the V4L2 subdev interface. With the goal to model the hardware links between the modules and to expose a clean, logical and usable interface, the driver is split into V4L2 sub-devices as follows.
There are two basic types of Microsoft Windows drivers:
User-mode drivers execute in user mode, and they typically provide an interface between a Win32 application and kernel-mode drivers or other operating system components.
For example, in Windows Vista, all printer drivers execute in user mode. For more information about printer driver components, see Introduction to Printing.
Kernel-mode drivers execute in kernel mode as part of the executive, which consists of kernel-mode operating system components that manage I/O, Plug and Play memory, processes and threads, security, and so on. Kernel-mode drivers are typically layered. Generally, higher-level drivers typically receive data from applications, filter the data, and pass it to a lower-level driver that supports device functionality.
Some kernel-mode drivers are also WDM drivers, which conform to the Windows Driver Model (WDM). All WDM drivers support Plug and Play, and power management. WDM drivers are source-compatible (but not binary-compatible) across Windows 98/Me and Windows 2000 and later operating systems.
Like the operating system itself, kernel-mode drivers are implemented as discrete, modular components that have a well-defined set of required functionalities. All kernel-mode drivers supply a set of system-defined standard driver routines.
The following figure divides kernel-mode drivers into several types.
As shown in the figure, there are three basic types of kernel-mode drivers in a driver stack: highest-level, intermediate, and lowest-level. Each type differs only slightly in structure but greatly in functionality:
Highest-level drivers. Highest-level drivers include file system drivers (FSDs) that support file systems, such as:
NTFS
File allocation table (FAT)
CD-ROM file system (CDFS)
Highest-level drivers always depend on support from underlying lower-level drivers, such as intermediate-level function drivers and lowest-level hardware bus drivers.
Intermediate drivers, such as a virtual disk, mirror, or device-type-specific class driver. Intermediate drivers depend on support from underlying lower-level drivers. Intermediate drivers are subdivided further as follows:
Function drivers control specific peripheral devices on an I/O bus.
Filter drivers insert themselves above or below function drivers.
Software bus drivers present a set of child devices to which still higher-level class, function, or filter drivers can attach themselves.
For example, a driver that controls a multifunction adapter with an on-board set of heterogeneous devices is a software bus driver.
Any system-supplied class driver that exports a system-defined class/miniclass interface is, in effect, an intermediate driver with one or more linked miniclass drivers (sometimes called minidrivers). Each linked class/minidriver pair provides functionality that is equivalent to that of a function driver or a software bus driver.
Lowest-level drivers control an I/O bus to which peripheral devices are connected. Lowest-level drivers do not depend on lower-level drivers.
Hardware bus drivers are system-supplied and usually control dynamically configurable I/O buses.
Hardware bus drivers work with the Plug and Play manager to configure and reconfigure system hardware resources, for all child devices that are connected to the I/O buses that the driver controls. These hardware resources include mappings for device memory and interrupt requests (IRQs). (Hardware bus drivers subsume some of the functionality that the HAL component provided in releases of the Windows NT-based operating system earlier than Windows 2000.)
Legacy drivers that directly control a physical device are lowest-level drivers.
With the HP Deskjet 2621, HP is introducing a multifunction device with network functionality and an LCD display. Light and compact, this device is not bulky and can be easily taken and used everywhere on the go. It is capable of providing black on white and color prints with a wifi function that will allow you to wirelessly print content from your smartphone or any other device. It certainly has a manual duplex function but with a very good quality ratio. Paper handling Paper can be printed in B5, A6, and A4 formats. You can save paper with the duplex function. This enables the device from the HP DeskJet series to print on the front and back of a sheet at the same time. Printing speed With a printing speed of 8 pages/min in black and white and 6 pages/min for color print jobs, the model works rather slowly. Printing a document is a job that sometimes rhymes with photocopying, scanning, and faxing. This is why it is often necessary to surround yourself with a device for each of these tasks. Several people did and bought a copier, printer, scanner, and fax machine for business purposes. But this practice quickly stopped when multifunction printers emerged. The HP Deskjet 2621 is one of those multifunction devices that have come to facilitate the user’s work. So, with just one small printer you can print, copy, scan, and fax any document. It is a technology that also considerably reduces the footprint with all these other devices. Now you can make room in your office or home by getting rid of all the other tools that don’t matter anymore. This printer also limits your movement because you will stay close to the device to perform these actions. However, with all the other machines, you had to go to either side of the room for each copy. In addition to individual documents, you can also place a book on the large glass surface and digitize it. You can connect this model to your home network and other devices in the house via LAN, USB, and WLAN. The HP Deskjet 2621 can also be used for wireless printing using a smartphone or tablet. It masters mobile technologies such as Apple AirPrint.
