IT Essentials Chapter 11 Exam Online

Wiring a PC to a printer can be done through the following connections: serial, parallel (IEEE 1284 and SCSI), USB, Firewire (IEEE 1394) and Ethernet. PS/2, HDMI, and eSATA connections are used for other purposes.

To connect a printer directly to the network an Ethernet connection through an RJ-45 interface would be used.

Thermal inkjet nozzles work based on heat creating steam bubbles. Piezoelectric inkjet nozzles work based on vibration of crystals.

The toner is applied to the latent image on the drum during developing. The toner attached to the latent image is transferred to the paper during transferring. The toner transferred is melted to the paper during fusing, and the drum gets a uniform negative charge during charging.

Heat is used during the fusing process in a laser printer to permanently fuse the toner to the paper.

Printer drivers are software programs that convert various media types in a document to a stream of commands in a language that the printer can understand. During a printer installation, Windows links an interface called “printer” with a specific driver that is compatible with the actual printer hardware.

When installing a new printer that is attached directly to a workstation, a technician should read the installation instructions carefully. For some printers, the printer driver should be installed on the computer before the printer is connected.

The Default Printer option is set globally and it will be the first printer to be chosen to print a job, unless Other Printer is selected in a Per-Document manner. Software-based printers are just instances of different kinds of printers, but for them to be chosen to do the job, they will need to be selected either as a default or per-document printer. There is no need to select a printer every time a printing job is sent.

Global settings act as default settings, whereas per-document settings are helpful with specialized documents, like letters and spreadsheets.

Calibrating the printer will align the heads and help in dosing the ink. The print spool problems are more related to queues. Color inkjet printers do not use drums or fusers.

Printer memory affects print speed and efficiency. Laser printers use memory to buffer print jobs, capturing them in printer memory while allowing computers to proceed with other work while printing.

The Additional Drivers button loads drivers in the sharing computer for other operating systems that the client computers may be running. For other printers in the network, the drivers must be loaded in the computers sharing the other printers. There is no need for additional drivers for duplex printing. The required drivers for other printers connected to the sharing computer will be loaded automatically.

Wireless printers can use Bluetooth, 802.11x, or infrared interfaces to connect wirelessly. WiMax, satellite, and microwave radio technologies are in practice never used to connect a printer to a network.

In both Windows 7 and 8, use the ​Network and Sharing Center control panel > Change advanced sharing settings to select the Turn on file and printer sharing option.

A dedicated PC print server has its own resources for the job and can manage several printers. A computer-shared print server uses its resources for sharing as well as for its own PC tasks. A hardware print server can only manage one printer, and a software print server cannot exist without hardware to run it.

A print server can provide client computers access to print resources, manage print jobs by storing them in a queue until the print device is ready for them, and provide print job status messages to users.

Resetting the page counters will assist in documenting printer usage and planning future maintenance. Cleaning parts only when they are no longer working, replacing consumables at set time intervals regardless of need, and disconnecting the printer from the power when it is not in use are not related to a preventive maintenance program.

The life of a thermal printer can be extended by cleaning the heating element regularly with isopropyl alcohol. A thermal printer does not use toner, so cleaning with a vacuum cleaner with a HEPA filter is not necessary. The condition of the paper and the cleanliness of the outside of the printer would probably do little to extend the life of the printer.

Testing a printer by restarting it and printing a test page are actions taken within the verification of the solution and system functionality step.

Recording the components and parts used to fix a printer problem is part of the documenting findings, actions, and outcomes step.

Humidity can cause sheets of paper to stick together which could cause paper jams. Using the wrong type of paper for a printer might also create a jamming issue.

If a printer is printing faded images, it is an indication that either the toner is low or the toner cartridge is defective.

Print spooler errors can occur when the printer service is stopped or not working properly. The first corrective action is to restart the print spooler. In some cases, it may be necessary to reboot the computer.

An inkjet printer will commonly fail to print when the inkjet cartridge is empty.

If the printer display is displaying nothing and the printer is not attempting to print a document, most likely the printer is turned off.
