Description

number. Value is from 1 to 14; countries/regions might limit the range of approved channels.

•(number): Value ranging from 1 to 14, depending on country/region.

•None: No channel is in use.

•Not Applicable: The WLAN is disabled or this parameter does not apply to this network type.

NOTE: In ad hoc mode, if you are not able to receive or transmit data between your computer and the HP All-in-One, make sure that you are using the same communication channel on your computer and the HP All-in-One. In infrastructure mode, the channel is dictated by the access point.

Type of authentication in use:

•None: No authentication in use.

•Open System (ad hoc and infrastructure): No authentication

•Shared Key: WEP key is required.

•WPA-PSK(infrastructure only): WPA with Pre-Shared Key.

•Not applicable: This parameter does not apply to this network type.

Authentication verifies the identity of a user or device before granting access to the network, making it more difficult for unauthorized users to access network resources. This security method is common on wireless networks.

A network using Open System authentication does not screen network users based on their identities. Any wireless user can have access from the network. However, such a network might use WEP (Wired Equivalent Privacy) encryption to provide a first level of security against casual eavesdroppers.

A network using Shared Key authentication provides increased security by requiring users or devices to identify themselves with a static key (a hexadecimal or alphanumeric string). Every user or device on the network shares the same key. WEP encryption is used along with shared key authentication, using the same key for both authentication and encryption.

Anetwork using server-based (WPA-PSK) authentication provides significantly stronger security, and is supported in most wireless access points and wireless routers. The access point or router verifies the identity of a user or device requesting access to the network before granting that access. Several different authentication protocols might be used on an authentication server.

The type of encryption in use on the network:

•None: No encryption is in use.

•64-bit WEP: A 5-character or 10-hex-digit WEP key is in use.

•128-bit WEP: A 13-character or 26-hex-digit WEP key is in use.

•WPA-AES: Advanced Encryption Standard encryption is in use. This is an encryption algorithm for securing sensitive but unclassified material by US Government agencies.

•WPA-TKIP: Temporal Key Integrity Protocol, an advanced encryption protocol, is in use.

•Automatic: AES or TKIP is in use.

•Not applicable: This parameter does not apply to this network type.

WEP aims to provide security by encrypting data over radio waves so that it is protected as it is transmitted from one end point to another. This security method is common on wireless networks.

This effective integration saves space and enhances productivity. The printers are equipped with a user-friendly control panel, simplifying navigation through different functions.

The print quality of these models is impressive, boasting a resolution that ensures sharp text and vibrant colors. The HP Vivera ink technology used in these printers plays a crucial role in delivering high-quality prints. This ink formulation provides a broader color gamut and enhanced longevity of prints, making them suitable for both professional documents and high-quality photos.

The HP C7280, C7250, and C7288 also feature built-in wireless connectivity options. Users can print from various devices, including smartphones, tablets, and laptops, making it possible to print from anywhere within range. This wireless technology offers flexibility and convenience, eliminating the clutter of cables in the workspace. Additionally, these models support HP’s ePrint feature, which allows printing via email, enabling users to send print jobs directly to the printer from any location.

Scanning and copying are facilitated by advanced optical scanning technology, which provides clear and precise results. Users can scan documents directly to a USB drive or email, streamlining sharing and archival processes. The automatic document feeder (ADF) featured in these models enhances efficiency, particularly for multi-page documents.

Durability is another characteristic of the HP C7280, C7250, and C7288. Designed for regular use, they come with a robust build quality and are engineered to handle large volumes of printing without frequent maintenance. The energy-efficient design of these printers also contributes to a lower environmental impact, aligning with modern sustainability practices.

In summary, the HP C7280, C7250, and C7288 series All-in-One printers excel in delivering multifunctionality, impressive print quality, and innovative technology. Their wireless capabilities, combined with user-friendly features and robust performance, make them a valuable addition to any home office or small business environment.
