What are the parts of laser printer and its functions?
A laserjet printer has many internal parts. I will briefly go over how a laserjet printer works and the basic parts.
Basic parts of a laserjet printer:
1. laser unit - beams an electrostatic image onto the drum
2. drum (OPC) - rolls the image onto the paper
3. toner/ cartridge - toner is used to create the image
4. fuser assembly - heats and presses the toner onto the page
1. The printer puts a negative charge on the paper.
3. The printer's laser spreads a negative electrostatic image onto a positively charged drum (reversing the polarity only where the image is)
2. The drum roller with the negatively charged image rolls over the positively charged toner, picking the toner on the image only (opposites attract).
3. The paper is then feed to the fuser unit where hot rollers heat up the paper and press the toner onto the paper. Since the toner is partly made up of plastic, the plastic melts and gets pressed to the paper making it adhere permanently.
4. The finished product is rolled out.

How do you disable printer spooling?
Windows defaults to spooling print jobs. The Print Spooler is a background program that writes data to temporary files in your C:WindowsTemp directory. Although this lets you perform other tasks while you print, it does slow printing. 1. On most printers, you can turn off the spooler by going to Start | Settings | Printers. Right-click on the icon of the printer you're using.
2. Click Properties and select the Details tab. Click on the Spool Settings button at the bottom of the dialog box.
3. Select the Print Directly to Printer option. This will tie up your application until the printer has all the data, but your print job should finish more quickly. Printing directly to the printer will also come in handy if your print spooler crashes and you need to print before you reboot your PC.
4. For troubleshooting, try printing from Notepad or WordPad to make sure that the problem is limited to just one application and isn't indicative of a problem with Windows. If the problem occurs in one document only, try to print a blank page inside the application. If this prints, the application may have problems with memory or fonts.

Why is a black cartridge added to the other color printer cartridges?
Where there is not a separate black cartridge, black is created by combining the other three colours - yellow, blue and red. This does not produce a black black. Also the three colour cartridges would be used up very fast if a lot of black text and graphics are printed. Therefore, a separate black cartridge is used to provide a really black ink, and to save the more expensive colour cartridges.
