THE MOST POPULAR TYPE OF PRINTER IN TODAYS MARKET IS INKJET PRINTER.  IT



USES A RESERVIOR OF INK, A PUMP AND A NOZZLE.  IT WORKS EFFECIENTLY AND T IS THE CHEAPEST PRINTER IN THE MARKET STARTING 1800 BUT THE PRINTER COST IS HIGHCOMPARING TO OTHERS TYPE OF PRINTER.


IT SPRAYS THE LIQUID INK ON TO A PAPER ACCORDING TO THE PATTERN OF PRINTED   DOCUMENTS.  IT SUPPORTS VERY HIGH DEFINATION OF THE DOCUMENT TYPES.


PARTS OF INKJET PRINTER:- INKJET PRINTER ARE SIMPLE DEVICE.  THEY CONTAINS VERY FEW PARTS.  THEY ARE INEXPENSIVE AND EASILY AVAILABLE IN THE MARKET.THE PARTS CAN BE DIVIDED INTO THE FOLLOWING CATEGORIES 


1) PRINT HEAD OF INK CARTRIDGE--> IT CONTAINS LIQUID INK AND TWO HUNDRED TINY NOZZLES TO SPRAY THE INK IN SMALL DROPLETS. MANY TIMES A PRINTER MAYCONTAIN A RESERVOIR OF INK.  MOST COMMON COLOURS ARE USED INTO SEPARATE CARTIDGE ONE FOR BLACK AND ANOTHER ONE FOR CYAN, MAGENTA AND YELLOW.  THERE ARE TWO METHODS OF SPRAYING THE INK.

THERMAL BUBBLE --> IT IS INVENTED BY HEWLET PACKARD AND IT USES A METAL PLATE AND A TUBE TO SUPPLY THE INK.  WHEN A PARTICULAR CHAMBER NEEDS TO SPRAY THE INK AN ELECTRIC SIGNAL IS SENT TO THE HEATING ELEMENT.  THE HEAT CAUSES THE INK TO FORM A BUBBLE AND PUSHED OUT OF THE PIN HOLE AND SPREAD ONTO THE PAPER.

PIEZO VIBRATOR--> IT IS INVENTED BY EPSON USES A MINIATURE DRUM OR PIEZO ELECTRIC ELEMENT THAT FLEXES WHEN CHARGE.  THE OUTWARD FLEX PUSHES THE INK FROM THE NOZZLE.  WHEN THE PRINTING IS DONE THE PRINT HEAD AND THE CARTRIDGE MOVES BACK TO THE MAINTENANCE SECTION.  IT CONTAINS A SMALL SECTION PUMP AND INK ABSORBING PAD.  THE SUCTION PUMP CLEANS THE NOZZLE AND EXPELLED INK IS ABSORBED BY THE PAD.


2) HEAD CARRIAGE BELT AND STEPPER MOTOR --> THE HEAD CARRIAGE CONTAINS THE INK CARTRIDGE WHICH MOVES BACK AND FORTH DURING PRINTING.   THE STEPPER MOTOR AND THE BELT MOVES THE HEAD CARRIAGE.  THIS ELECTRIC MOTOR CAN MOVE IN VERT SMALL INCREMENTS.  A BELT IS PLACED AROUND TWO SMALL WHEELS ATTACH TO THE PRINT HEAD CARRIAGE.  THIS BELT IS DRIVEN BY THE STEPPER MOTOR AND MOVES THE PRINT HEAD BACK AND FORTH.


3) PAPER FEED MECHANISM--> IT PICKS UP A PAPER FROM THE PAPER TRAY.  THE PICKUP ROLLER, WHICH ARE SEVERAL RUBBER ROLLER WITH A SLIGHTLY FLAT SPOT .  THEY RUB AGAINST THE PAPER AND FEED ONLY ONE PAPER INSIDE THE PRINTER AND REST OF THE PAPER PLACED IN THE PAPER TRAY. THE ROLLER IS MOVED BY BACKUP STEPPER MOTOR.   THE PAPER TRAY IS A SIMPLE PLASTIC TRAY WHICH HOLDS THE PAPER.   SOME PRINTERS HAS THE PAPER TRAY IN THE BACK SIDE.  THERE IS NO REAL REASON WHICH MANUFACTURES MAKES THE PAPER TRAY INFRONT OR BACK.  THE PAPER FEED SENSOR TELLS A PRINTER WHEN THERE IS NO PAGE IN THE PAPER TRAY OR A PAPER JAM OCCURS.   


4) CONTROL INTERFACE AND POWER CIRCUIT--> THE PRINTER CONTROL CIRCUITS ARE USSUALLY  OR A SMALL CIRCUIT BOARD REFFERED AS MOTHER BOARD THAT CONTAINS ALL CIRCUIT TO RUN STEPPER MOTOR PAPER FEED MOTOR AS THE PRINTER NEED.  IT ALSO MONITORS THE HEALTH OF A PRINTER AND REPORTS BACK TO THE PC .  THE INTERFACE CIRCUIT CONNECTS A PRINTER WITH  A COMPUTER USING SEVERALPARALLEL USB,  LANPORT.  IT RECIEVES THE DATA SIGNALS COMING FROM THE COMPUTER AND CONVERTS INTO TO SIGNALS WICH A PRINTER CAN UNDERSTAND.   THE FINAL PARTS OF THE POWER CIRCUIT IS THE POWER SUPPLY UNIT .   IT COVERTS 210 VAC INTO  12 AND 5 VOLT DC.  THIS IS ACCOMPLISHED BY A TRANSFORMER.


NOW LET US SEE HOW A PRINTER PRINTS A DATA OR IMAGE

1. YOU CLICK THE PRINT BUTTON ON A SOFTWARE TO PRINT A DOCUMENT.

2. THE SOFTWARE SENDS THE DATA TO A PRINTER DRIVER.

3. THE PRINTER DRIVER CONVERTS THE DATA INTO THE FORMAL THAT THE PRINTER CAN UNDERSTAND AND ALSO ENSURES THE PRINTER IS READY TO PRINT.

4. THE DRIVER SENDS THE DATA VIA A USB PARALLEL R NETWORK PORT TOWARDS HE PRINTER.

5. THE PRINTER STORES THE RECEIVED DATA IN A BUFFER.

6. THE PRINTER STARTS CLEANING CYCLE .  THE SUCTION PUMP PRINTS OUT DRY INK AND CLEARS THE NOZZLE.

7. THE PAPER FEED MOTOR INSERTS A PAPER INSIDE THE PRINTER.  IF THERE IS NO PAPER THE NOTIFICATION LED IS TURNED ON AND MESSAGE IS SENT TO THE COMPUTER.

8. ONCE THE PAPER IS IN RIGHT POSITION, THE STEPPER MOTOR AND BELT MOVES THE CARTRIDGE ACROSS THE PAGE LITTLE BY LITTLE. THE CARTRIDGE SPRAYS THE INK ON PAPER DEDICATED BY THE MOTHERBOARD AND MAKES THE PATTERN OF THE DOCUMENT.

9. AT THE END OF THE PASS ACROSS THE PAGE FEED MOTOR ADVANCES THE PAGE SMALL AMOUNT AND STEP 8 REPEATS.  THE PROCESS CONTINUES UNTIL THE PAGE IS FINISHED.

10. IF MORE PAGE IS NEEDED THE PROCESS START FROM STEP 7.

11. ONCE THE PRINTING IS COMPLETED AND THE LAST PAPER EJECTS.  THE PRINT HEAD IS PARKED AND THE PRINT PROCESS IS FINISHED.

WINDOWS TO GO


What is windows to go?

Windows to go is an important deployment option in windows 8.1 and above.  Windows to go assist to deploy the windows 8.1 enterprise to a specialy prepared usb storage device and then use this usb storage to start any compatible computer.
windows to go,windows 10,windows,windows 8,windows to go usb,windows to go creator,windows 2 go,win to go,to go,windows 10 to go,microsoft windows (operating system),what is windows to go,ssd에 windows to go,windows to go meaning,windows 10 to go drive,windows to go usb stick,windows to go windows 10,windows 10 windows to go,windows to go hard drive,windows to go definition,windows 7


  when a windows to go device is started on a new computer, the boot process detects the computer hardware and installs appropriate drivers.

  when the same windows to go to start a same computer, then windows to go starts normally automatically by loading the appropriate drivers.  It stores the hardware configurations of multiple computers.

Windows to go restriction

Windows to go functions in a way that is very similar to a traditional windows 8.1 desktop deployments, but with the following restrictions:
·         In the windows to go default setting sleep and hibernation is disabled.  The functionality can be enabled by configuring group policy but it can lead to data corruption.
·         As a security measure, fixed internal discs on the hosts computer are offline to ensure that by using windows to go, third parties do not gain access to files on the host computer file system by booting computers.
·         As windows to go device will be used across multiple computers bit locker uses a boot password rather than a tpm password.\
·         In windows to go, windows recovery environment (re) and push button reset are disabled.
·         Windows to go devices supports only windows 8.1 enterprise edition.
·         Computer with an x86 or an x64 processor can use usb storage device prepared with an x86 version of windows to go.
·         A computer having an x64 compatible processor can only use an computer prepared with an x64 version of windows to go.
·         Windows to go doesnot support windows rt devices.
·         In windows to go default setting, the windows store is disabled.
·         The usb storage device with the windows to go deployment can be removed from the computer for up to 60 seconds.  The computer restarts, if the usb device is not reconnected at the time of deployment.

Windows to go requirements


Windows to go only works with microsoft certified usb storage devices and the operating system should recognize the usb device as  a fixed disk.  Create windows to go devices by using the windows to go wizard.  Systems running windows 8.1 enterprise eddition can only provides this wizard.  The computers connected to a usb 2.0 or usb 3.0 port can be stated with windows to go device.

Comparing windows to go and traditional windows 8.1 deployments

Windows to go and traditional deployments differ in several ways and both methods have their benefits and drawbacks. Some of the key differences as follows:
·         Windows to go required the computer to boot from a usb device.  Enabling boot from usb poses a security risk  because it can allow access to a computers volumes if technologies such as bitlocker are not in use.  Organizations should be wary of allowing non administrative users to boot from usb devices.
·         In a traditional deployment, bit locker can be configured to use tpm.  Windows to go doesn’t have this security and only allows bit lockers to use a passphrase.  The windows to go boot environment might be modified by malacious software.
·         The windows store is disabled by default in windows to go. Changing this is possible by editing the allow store to install applications on the windows to go workspaces policy settings located in the computer configuration \administrative templates\windows components\store node of the group policy management editor.  In window 8.1 window store is enabled by default.
·         Windows to go default setting disables sleep and hibernation and enabled on traditionally deployed windows 8.1 systems.  If windows to go device is left in running computer accidently the computer will not shut down.
·         In a traditional installation, data is stored locally on hard disks.  In windows to go data is stored in usb device. Usb devices are more likely to fail which means the local data is more likelyu to be lost.  Users are also are more likely misplace a usb device than a portable computer.
·         With a compatible hardware user  can access their applications and data.  Windows to go allows users to taske their applicationsand data.
·         Windows to go assists information technology (it) departments that want to allow users to use their own devices, but also want to ensure that only securely managed operating system can interact with sensitive services on a network.


Booting from a native boot virtual hard disk

Virtual hard disk with for native boot assists in configuring windows 8.1 pro and enterprise editions which have a .vhd or .vhdx extensions.

  configure a computer to start from a single virtual hard disk or from different virtual hard disks.  In comparision to configuring traditional dual boot, booting from a virtual hard disk is beneficial because it does not require creating a new volume while deploying an additional operating systems.  Configuration is possible to boot between multiple virutal hard disk files stored on the same intensity.


Planning for virtual hard disk with native boot

Configuring a virtual hard disk with native boot includes the following process:
·         Creating and performing a virtual hard disks,
·         Installing or applying windows image,
·         Adding the virtual hard disk native boot option to the startup menu and,
·         Restarting the computer.

With disk management or diskpart.exe create a virutal hard disk deploy window images by using dism.exe and add the boot option by using bedboot.exe.
The main points to consider whenpolanning for virtual hard are volume size, deployment options and operating systems.
