IT Essentials V5 Chapter 9

The computer will choose the printer that is set as the default printer to be the first option for printing. This means that when the user initiates a print command, the computer will automatically select the default printer as the primary choice for printing without requiring any manual selection.

The desired quality of the image affects the speed of an inkjet printer because higher quality images require more ink to be applied to the paper, which takes more time. Lower quality images require less ink and can be printed faster.

FireWire and serial cables are used to connect a computer to a printer. FireWire is a high-speed data transfer cable commonly used for connecting devices such as printers, scanners, and external hard drives to a computer. Serial cables, on the other hand, are used for connecting older printers or devices that use serial ports for communication. PS/2, HDMI, and eSATA cables are not typically used for connecting a computer to a printer.

The possible cause of none of the users being able to print, but still being able to access shared resources on the computer to which the printer is locally connected, is that the cable connecting the printer to the PC is faulty. A faulty cable can prevent the printer from receiving print jobs from the users' computers, while still allowing the users to access shared resources on the connected computer.

The correct answer is that the printer does not have enough memory to buffer an entire photograph. When high-resolution photographs are being printed, they require a large amount of memory to process and print the image. If the printer does not have enough memory, it will struggle to handle the data and may result in slow response times. This can cause the computers on the LAN to also slow down as they wait for the printer to complete its tasks.

The technician could ask the user if they can print a test page on the printer to determine if the printer is functioning properly. Additionally, they could ask if the printer is powered on to ensure that it has power and is ready to print. These closed-ended questions provide specific information that can help the technician identify the problem with the printer.

Cleaning the heating element regularly with isopropyl alcohol can extend the life of a thermal printer. The heating element is a crucial component of a thermal printer that is responsible for creating the heat necessary to produce the printed image. Over time, dust, debris, and ink residue can accumulate on the heating element, which can affect its performance and lead to malfunctions. Regularly cleaning the heating element with isopropyl alcohol helps remove these contaminants and ensures that the printer operates efficiently, thus prolonging its lifespan.

To install a new USB printer on a PC running Windows 7 Professional, the user should connect the printer to the PC and power it on. Windows will automatically detect the printer and install the necessary drivers. This is the easiest and most common method of installing a USB printer on a Windows 7 PC. There is no need to configure the BIOS or manually copy the printer driver to the System32 folder. The user can also navigate to the Control Panel and add the printer from there, but simply connecting and powering on the printer is sufficient for Windows to install the drivers.

The two methods to share a printer wirelessly are infrared and IEEE 802.11 standards. Infrared technology allows for wireless communication by using infrared light waves. This method requires the printer and the device sending the print job to be in close proximity. IEEE 802.11 standards, commonly known as Wi-Fi, enable wireless communication over a local area network. This method allows for more flexibility as the printer and the device can be located in different areas within the network range.

Calibrating the printer can solve the problem of an inkjet color printer printing different colors from those shown on the screen. Calibration ensures that the printer's color settings are aligned with the colors displayed on the screen, resulting in accurate color reproduction. This process adjusts the printer's color profiles and settings to match the specific color requirements, improving color accuracy and consistency in the printed output. It is a common solution for resolving color discrepancies between the screen and the printed document.

A bad cable connection can be a probable cause of the problem because if the cable connecting the printer to the computer is faulty or not properly connected, the printer may not receive the print job signal, resulting in the document not being printed.

In a Windows 7 environment, network printer sharing would be configured in the Network and Sharing Center. This is because the Network and Sharing Center is the central location where users can manage and configure their network connections and settings. Within the Network and Sharing Center, users can access various options for sharing resources, including printers, with other devices on the network. Therefore, it is the appropriate location to configure network printer sharing in a Windows 7 environment.

Thermal inkjet nozzles work by applying heat to the ink reservoir, which creates a bubble of steam in the chamber. This bubble then forces the ink out of the nozzle onto the paper, creating the desired image. The heat is used to generate the steam bubble, which in turn controls the flow of ink. The other options mentioned, such as the vibration of the crystal or the application of a charge to the printhead, are not characteristics of thermal inkjet nozzles.

The technician is applying the step of verifying the solution and system functionality. After applying a solution to a printer problem, the technician restarts the printer and prints a test page to ensure that the solution has resolved the issue and that the printer is functioning properly. This step is important to confirm that the problem has been resolved and that the system is working as expected.

The technician just performed the step of documenting findings, actions, and outcomes. This is evident from the fact that the technician recorded the installation of a new fuser roller unit in the laser printer. By documenting this information, the technician is keeping a record of the action taken to solve the printing problem and the outcome of that action. This step is important for future reference and to track the progress of troubleshooting efforts.

Per-document options override global options means that when printing a document, any specific settings chosen for that document will take priority over the general settings that have been set globally. This allows for more flexibility and customization when printing different documents with varying requirements.

Developing is the correct answer because in laser printing, developing is the process of applying toner to the latent image on the drum. This process involves using a developer unit to attract and adhere the toner particles to the charged areas on the drum, creating a visible image that can be transferred and fused onto paper during subsequent steps in the printing process.

The PostScript language is known for its ability to handle complex printing jobs. It is a page description language that allows for precise control over the layout and appearance of printed documents. PostScript is commonly used in professional printing environments where high-quality output and complex graphics are required. It is not specifically known for printing faster than other languages or requiring less printer memory. Additionally, while PostScript can be rendered on a local workstation, it is not the only language that allows for this.

A laser printer maintenance kit typically includes two replacement parts: transfer rollers and fuser assembly. Transfer rollers are responsible for transferring the toner from the cartridge onto the paper during the printing process. The fuser assembly is responsible for applying heat and pressure to bond the toner onto the paper. Both of these components are crucial for maintaining the printer's performance and ensuring high-quality prints.

A print server has two main functions: providing print resources to all connected client computers and storing print jobs in a queue until the printer is ready. By providing print resources, the print server allows all connected clients to access and use the printer efficiently. Storing print jobs in a queue ensures that multiple print jobs can be processed in an orderly manner, preventing any conflicts or delays in printing. This allows for a smoother printing experience and ensures that print jobs are not lost or overwritten.

The purpose of the Additional Drivers button in the Sharing tab of the Printer Properties is to add additional drivers for other operating systems. This allows users with different operating systems to connect and use the printer without compatibility issues.

Resetting the printer page counters if available supports an effective printer preventive maintenance program. Page counters keep track of the number of pages printed, and resetting them allows for accurate monitoring of printer usage. By resetting the counters, it becomes easier to determine when maintenance tasks, such as cleaning or replacing parts, should be performed. This helps to prevent issues and prolong the lifespan of the printer.
