Selecting print media

The printer is designed to work well with most types of office paper. It is best to test a variety of print media types before buying large quantities. Use HP media for optimum print quality. Visit HP website at www.hp.com

for details on HP media.

Tips for selecting and using print media

For the best results, observe the following guidelines.

● Always use media that conforms to the printer specifications. See

the tray. See Loading media

● Load only one type of media at a time into a tray.

● For tray 1 and tray 2, load media print-side down and aligned against the right and back edges of

● Tray 2 is designed to hold only plain paper.

● Do not overload the trays. See

Printing on both sides (duplexing) .

● To prevent jams, poor print quality, and other printer problems, avoid the following media:

● Multipart forms

● Media that is damaged, curled, or wrinkled

● Media with cutouts or perforations

● Media that is heavily textured, embossed, or does not accept ink well

● Media that is too lightweight or stretches easily

Cards and envelopes

● Avoid envelopes that have a very slick finish, self-stick adhesives, clasps, or windows. Also avoid cards and envelopes with thick, irregular, or curled edges, or areas that are wrinkled, torn, or otherwise damaged.

● Use tightly constructed envelopes, and make sure the folds are sharply creased.

● Load envelopes into the printer with the flaps facing up.

Photo paper

● Use the Best mode to print photographs. Note that in this mode, printing takes longer and more memory is required from your computer.

● Remove each sheet as it prints and set it aside to dry. Allowing wet media to stack up may cause smearing.

14 Chapter 3 Using the printer ENWW

ENWW

Transparencies

● Insert transparencies with the rough side down and the adhesive strip pointing towards the back of the printer.

● Use the Best mode to print transparencies. This mode provides longer drying time and ensures that the ink dries completely before the next page is delivered to the output tray. Allowing wet media to stack up may cause smearing.

Custom-sized media

● Use only custom-sized media supported by the printer.

● If your application supports custom-sized media, set the media size in the application before printing the document. If not, set the size in the printer driver. You might need to reformat existing documents to print them correctly on custom-sized media.

20 Chapter 3 Using the printer ENWW

Configuring trays

By default, the printer draws media from tray 1. If tray 1 is empty, the printer draws media from tray 2

(if it is installed and loaded with media). You can change this default behavior using the following features.

● Tray Lock: Use this feature to protect special media such as letterhead or preprinted media from accidental use. If the printer runs out of paper while printing a document, it will not use paper from a locked tray to complete the print job.

● Default Tray: Use this feature to determine the first tray from which the printer draws media.

NOTE To use the tray lock and default tray settings, you must select the automatic tray selection option in the printer software. If the printer is on a network and you set a default tray, the setting will affect all users of the printer.

Tray 2 is designed to hold only plain paper.

To configure the trays

Make sure the printer is turned on.

Perform one of the following: a. Embedded Web server: Click the Settings tab and click Paper Handling in the left panel.

b. Printer driver (Windows): Click the Services tab. For Windows 2000, Windows XP, and

Printing on both sides (duplexing)

You can print on both sides of a sheet of media, either automatically by using the optional automatic two-sided printing accessory (duplex unit), or manually by turning the media over and feeding it into the printer again.

Guidelines for printing on both sides of a page

● Always use media that conforms to the printer specifications. See

● Specify duplex options in your application or in the printer driver.

● Do not print on both sides of transparencies, envelopes, photo paper, glossy media, or paper lighter than 16 lb bond (60 g/m 2 ) or heavier than 28 lb bond (105 g/m 2 ). Jams might occur with these media types.

● Several kinds of media require a specific orientation when you print on both sides of a page, such as letterhead, preprinted paper, and paper with watermarks and prepunched holes. When you print from a computer running Windows, the printer prints the first side of the media first.

When you print from a computer using the Mac OS, the printer prints the second side first. Load the media with the front side facing down.

● For auto-duplexing, when printing finishes on one side of the media, the printer holds the media and pauses while the ink dries. Once the ink dries, the media is pulled back into the printer and the second side is printed. When printing is complete, the media is dropped onto the output tray.

Do not grab it before printing is complete.

● You can print on both sides of supported custom-sized media by using the printer's manual duplex capabilities. For a list of supported custom-sized media, see

Load the appropriate media. See Guidelines for printing on both sides of a page

To use the printer with any wireless connection, you must run the installation program at least once from the Starter CD and create a wireless connection.

Make sure the printer is not connected to the network using a network cable.

The sending device must have built-in 802.11 capabilities or an 802.11 wireless card installed.

It is recommended that the printer and the computers that use the printer be on the same subnet.

Before installing the printer software, you may wish to find out the settings of your network. Obtain the information from your system administrators, or complete the following tasks:

● Obtain your network's network name (SSID) and communication mode (infrastructure or ad hoc) from the configuration utility for the network's wireless access point (WAP) or the computer's network card.

● Find out the type of encryption your network uses, such as Wired Equivalent Privacy (WEP).

● Find out the security password or encryption key of the wireless device.

Understanding 802.11 wireless network settings

Network name (SSID)

By default, the printer looks for the wireless network name or Service Set Identifier (SSID) named

"hpsetup". Your network may have a different SSID.

Communication mode

There are two communication mode options:

● Ad hoc: On an ad hoc network, the printer is set to ad hoc communication mode, and communicates directly with other wireless devices without the use of a wireless access point

(WAP).

ENWW Setting up the printer for wireless communication (HP Officejet Pro K550dtwn) 85

All devices on the ad hoc network must:

● Be 802.11 compatible

● Have ad hoc as the communication mode

● Have the same network name (SSID)

● Be on the same subnet and same channel

● Have the same 802.11 security settings

● Infrastructure (recommended): On an infrastructure network, the printer is set to infrastructure communication mode, and communicates with other devices on the network, whether the devices are wired or wireless, through a WAP. WAPs commonly act as routers or gateways on small networks.

Security settings

NOTE For the available settings for the printer, see the network configuration page under

the instructions under Troubleshooting tips and resources ) and repeat the steps. See also

For more information on wireless security, visit www.weca.net/opensection/pdf/whitepaper_wi-fi_security4-29-03.pdf

● Network authentication: The printer's factory default setting is 'Open', which does not require security for authorization or encryption. The other possible values are 'OpenThenShared',

'Shared', and 'WPA-PSK' (Wi-Fi ® Protected Access Pre-Shared Key).

▲ WPA increases the level of over-the-air data protection and access control on existing and future Wi-Fi networks. It addresses all known weaknesses of WEP, the original native security mechanism in the 802.11 standard.

▲ WPA2 is the second generation of WPA security; providing enterprise and consumer Wi-Fi users with a high level of assurance that only authorized users can access their wireless networks.

● Data encryption:

● Wired Equivalent Privacy (WEP) provides security by encrypting data sent over radio waves from one wireless device to another wireless device. Devices on a WEP-enabled network use WEP keys to encode data. If your network uses WEP, you must know the WEP key(s) it uses.

● WPA uses the Temporal Key Integrity Protocol (TKIP) for encryption and employs 802.1X

authentication with one of the standard Extensible Authentication Protocol (EAP) types available today.

● WPA2 provides a new, encryption scheme, the Advanced Encryption Standard (AES). AES is defined in counter cipher-block chaining mode (CCM) and supports the Independent Basic

Service Set (IBSS) to enable security between client workstations operating in ad hoc mode.

Guidelines for reducing interference on a wireless network

The following tips will help reduce the chances for interference in a wireless network:

● Keep the wireless devices away from large metal objects, such as filing cabinets, and other electromagnetic devices, such as microwaves and cordless telephones, as these objects can disrupt radio signals.

● Keep the wireless devices away from large masonry structures and other building structures as these objects can absorb radio waves and lower signal strength.

● For an infrastructure network, position the WAP in a central location in line of sight with the wireless devices on the network.

● Keep all wireless devices on the network within range of one another.

Guidelines for ensuring wireless network security

To add hardware addresses to a wireless access point (WAP)

MAC filtering is a security feature in which a wireless access point (WAP) is configured with a list of

MAC addresses (also called "hardware addresses") of devices that are allowed to gain access to the network through the WAP.

If the WAP does not have the hardware address of a device attempting to access the network, the

WAP denies the device access to the network.

If the WAP filters MAC addresses, then the printer's MAC address must be added to the WAP's list of accepted MAC addresses.

Print the network configuration page. See

Ordering printing supplies online

Open the WAP's configuration utility, and add the printer's hardware address to the list of accepted MAC addresses.

Other guidelines

To keep the wireless network secure, follow these guidelines:

● Use a password with at least 20 random characters. You can use up to 63 characters in a WPA password.

● Avoid any common words or phrases, easy sequences of characters (such as all 1's), and personally-identifiable information for passwords. Always use random strings composed of uppercase and lowercase letters, numbers, and if allowed, special characters such as punctuation.

● Change the password periodically.

● Change the default password provided by the manufacturer for administrator access to the access point or wireless router. Some routers let you change the administrator name as well.

● Place the access point or router in the center of a room and not near a window.

● Turn off administrative access over wireless if possible. If you do this, you need to connect to the router with a wired Ethernet connection when you want to make configuration changes.

90 Chapter 6 Configuring and managing the printer ENWW

● Turn off remote administrative access over the Internet on your router, if possible. You can use

Remote Desktop to make an encrypted connection to a computer running behind your router and make configuration changes from the local computer you are accessing over the Internet.

● To avoid accidentally connecting to another party's wireless network, turn off the setting to automatically connect to non-preferred networks. This is disabled by default in Windows XP.

If you believe your ink supply or printhead is defective, you may return it for a refund or replacement provided that ALL of the following are true:

● Ink supply: it is not out of ink

● Ink supply: it has not been refilled, remanufactured, or otherwise tampered with

● Ink supply: it is not past the "end of warranty" date on the product label

● Printhead: it is not past 1 year from date of printhead installation or not past end of warranty date on the printhead, whichever is later

To determine the date of printhead installation, see the "Printhead Status" section on the configuration page.

End of warranty date locations:

Date format: YYYY/MM/DD

HP Inkjet Supplies Expiration

As ink ages, it loses water. When ink is old enough, it can damage the printheads or other parts of the printing system. In normal use, most ink cartridges will run out of ink long before the ink is old enough to cause damage. It is recommended to replace the ink cartridge before the expiration date is reached. If expired ink is detected, the printer will pause printing, you will need to accept the use of expired ink, and then the printing will resume. See "Expiration date (Y-M-D)" located under the "Ink

Cartridge Status" section on the configuration page.

How do you return a product?

There are two ways to return a product under warranty:

● Visit the retailer where you bought the product (subject to the retailer's return policy).

● If you cannot return the product to the retailer, visit HP website ( www.hp.com/support/ officejetprok550 ) or call the support phone number listed on the product insert that came in the box with the product.
