HP Designjet 4500 Printer Series - Embedded Web Server

Embedded Web Server

The Embedded Web Server is the control center for remote management of the printer. From any computer, an ordinary Web browser can be used to contact the printer's Embedded Web Server.

The following can be done with the Embedded Web Server:

  • Submit jobs to the printer in various file formats (HP-GL/2, HP-RTL, PostScript, PDF, JPEG, TIFF, CALS G4) without the need of a driver or an application.

  • View the status of the ink cartridges, the printheads, the printhead cleaners, and the paper.

  • View statistics on ink and paper usage.

  • Request email notification when specified warning or error conditions occur (such as low ink level).

  • Update the printer's firmware.

  • Change various printer settings (on the Device Setup page).

  • Set a password to restrict web access to the printer.

Cancel a job

A job can be canceled from the front panel by pressing the Cancel key, or from the Embedded Web Server by selecting the job and clicking the Cancel icon.

The printer advances the paper as though the print were finished.

NOTE: A multi-page job or a big file may take longer to stop printing than other files.

top

Managing the print queue

Printer can store pages in a queue while it is printing the current page. The queue may contain pages from more than one job.

NOTE: This information applies only if the drivers that came with the printer or the Embedded Web Server to submit printing jobs is used.

Turning off the queue [4000]

HP Designjet 4000 series users can turn off the queue from the Web server (Settings tab then Device setup followed by Queue ), or from the front panel: select the (folders) icon and then Job management options followed by Disable queue .

HP Designjet 4500 series users cannot turn off the queue.

The When To Start Printing options

NOTE: The When To Start Printing options cannot be used with PostScript jobs.

A file in the queue can be printed at whatever time. From the Web server, select the Settings tab then Device setup followed by When to start printing ; or, from the front panel, select the (folders) icon and then Job management options followed by When to start printing .

The three options that can be selected are:

  • When After Processing is selected, the printer waits until the whole page has been processed and then it starts to print. This is the slowest setting but offers the best print quality.

  • When Immediately is selected, the printer prints the page as it is processed. This is the quickest setting, but the printer may stop halfway through a print to process data. This setting is not recommended for complex images with dense color.

  • When Optimized is selected (this is the default setting), the printer calculates the best time to begin printing the page. It is usually the best compromise between the After Processing and Immediately settings.

Identifying a job in the queue

The best way to look at the queue is in the Embedded Web Server (Click Information and then Jobs queue ), where the queue and get full information on every job can be managed (by clicking the name of the file).

However, queue can also be managed from the front panel. To do so, select the (folders) icon and then Job queue , where a list of the jobs in the queue can be seen.

Each has an identifier, comprising:

<position in queue>: <image name>

The job currently being printed is in position 0. The next job to be printed is in position 1, the previous job already printed is in position -1.

top

Prioritizing a job in the queue

To make any job in the queue the next one to be printed, select it and choose Reprint (in the Embedded Web Server) or Move to front (in the front panel).

If nesting is turned On, the prioritized job may still be nested with others. If this job is to be printed next, and on its own on the roll, first turn nesting off and then move it to the front of the queue as described above.

top

Deleting a job from the queue

Under normal circumstances, there is no need to delete a job from the queue after printing it, as it will just fall off the end of the queue as more files are sent. However, if a file is sent in an error, and to avoid any chance of it being reprinted, simply delete it, by selecting it and choosing Delete (in the Embedded Web Server or in the front panel).

In the same way, a job that has not been printed yet can be deleted.

If the job is currently being printed (Status = printing in the Web server, or its queue position is 0 in the front panel), to both cancel the job and to delete it, first click the Cancel icon in the Web server, or press the Cancel key on the front panel, and then delete it from the queue.

top

Making copies of a job in the queue

To make extra copies of any job in the queue, select the job in the Embedded Web Server and click the Reprint icon, then specify the number of copies to be printed. The job will be moved to the top of the queue. To do this from the front panel: select the Job and choose Copies , then specify the number of copies required and press the Select key. This overrides any value set by the software.

NOTE: If Rotate was On when the file was sent, every copy will be rotated.

If the job has already been printed, use Move to front to move it to the top of the queue.

Understanding job status

These are the possible job status messages, approximately in the order in which they may be seen:

  • receiving : the printer is receiving the job from the computer.

  • waiting to process : the job has been received by the printer and is waiting to be rendered.
    NOTE: For jobs submitted through the Embedded Web Server only.
  • processing : the printer is parsing and rendering the job.

  • preparing to print : the printer is performing writing system checks before printing the job.

  • waiting to print : the job is waiting for the print engine to become free to proceed with printing.

  • waiting for nest : the printer is set up with Nesting=On and is waiting for other jobs in order to complete the nest and proceed with printing.

  • on hold : the job was sent with the on hold for preview option and is on hold.
    NOTE: If the printer hangs up while printing a job, and the queue facility is turned on, the partially printed job will appear in the queue as on hold when the printer is next turned on. When the job is resumed, it will start printing at the page at which it was interrupted.
  • on hold for paper : the job can't be printed because the paper it needs is not loaded in the printer, load the required paper and then click Continue to resume the job.

  • on hold for accounting : the job can't be printed because the printer requires all jobs to have an account ID, enter the account ID and then click Continue to resume the job.

  • printing

  • drying

  • cutting paper

  • ejecting page

  • canceling : the job is being canceled, but will remain in the printer job queue.

  • deleting : the job is being deleted from the printer.

  • printed

  • canceled : the job has been canceled by the printer

  • canceled by user

  • empty job : the job does not contain anything to print.

Nest jobs to save roll paper

Nesting means placing pages side by side on the paper, rather than one after the other. This is done to avoid wasting paper.

Figure 2: Nesting of paper

1 - Direction of paper flow.
2 - Nesting off.
3 - Nesting on.
4 - Paper saved by nesting.

When does the printer try to nest pages?

When both of the following are true:

  • The printer is loaded with roll paper, not sheet paper.

  • In the front panel's Job Management menu or the Embedded Web Server's Device Setup page , 'Nest' is On.

top

Which pages can be nested?

All pages can be nested, unless they are so large that two of them cannot fit side by side on the roll, or unless there are too many of them to fit into the remaining length of the roll. A single group of nested pages cannot be split between two rolls.

top

Which pages qualify for nesting?

In order to be in the same nest, the individual pages must be compatible in all of the following ways:

  • All pages must have the same print quality setting (Fast, Normal, or Best).

  • Pages must be all Optimized for Drawings/Text or all Optimized for Images.

  • The Maximum Detail setting must be the same on all pages.

  • The Margins setting must be the same for all pages (Extended or Normal).

  • The Mirror setting must be the same for all pages.

  • The Rendering Intent must be the same for all pages.

  • The Cutter setting must be the same for all pages.

  • The color adjustment settings must be the same for all pages. These are known as Advanced Color Settings in the Microsoft Windows driver, and CMYK Settings in the Macintosh Operating System driver.

  • Pages must be all color, or all grayscale; not some in color and some in grayscale.

  • All pages must be in one or other of the following two groups (the two groups cannot be mixed in the same nest):

    • HP-GL/2, RTL, CALS G4

    • PostScript, PDF, TIFF, JPEG

  • JPEG, TIFF, and CALS G4 pages with resolutions greater than 300 dots-per-inch (dpi) may not nest with other pages in some cases.

top

How long does the printer wait for another file?

So that the printer can make the best nest possible, it waits after a file has been received to check whether a subsequent page will nest with it or with pages already in the queue. This waiting period is the nest wait time; the factory default nest wait time is two minutes. This means that the printer waits for up to two minutes after the last file is received before printing the final nest. This waiting time from the printer's front panel can be changed. Select the (folders) icon, then Job management options then Nest options followed by Select wait time . The available range is 1 to 99 minutes.

While the printer is waiting for nesting to time out, it displays the remaining time on the front panel. nest can be printed (cancel the nest wait) by pressing the Cancel key.

Using IP over FireWire with Mac OS X 10.3 and later

If Macintosh OS X 10.3 or a later version is used, and there is a FireWire connection to the printer, it is possible to set up an IP address for the printer in order to use the Embedded Web Server. To do this:

  1. Open System Preferences and click Network .

  2. Choose Network Port Configurations from the Show popup menu.

  3. If there is no FireWire port configuration in the list, click New , then choose FireWire from the Port popup menu. New port configuration cannot be given a name, such as FireWire.

  4. Drag the port configuration to the top of the Port Configuration list. This ensures that the port is assigned an IP address.

  5. Click Apply Now .

If the FireWire port configuration is not dragged to the top of the Port Configuration list, it needs to be chosen Manually (or DHCP with manual address) from the Configure IPv4 popup menu, and then an IP address needs to be entered. Click here for details or updated information on activating IP over FireWire Non-HP site

When the printer is connected through FireWire, it is recommended to add the printer using the FireWire modules in order to take full advantage of FireWire printing, and to use the IP over FireWire only to visit the printer’s Embedded Web Server.

If the printer is connected through FireWire and the printer is also connected to the network through Fast Ethernet or Gigabit Ethernet, the printer’s IP over FireWire will not be available and it will not be possible to access the Embedded Web Server from the Printer Dialog. However, it will be possible to print through FireWire.

Also in the case of printer sharing over FireWire, remote users will not be able to access the Embedded Web Server from the Printer Dialog, although they will be able to print.

Change the language of the Embedded Web Server

The Embedded Web Server can work in the following languages: English, Portuguese, Spanish, Catalan, French, Italian, German, Simplified Chinese, Traditional Chinese, Korean, and Japanese. It will choose whichever language is specified in Web browser's options. If a language that cannot be supported is specified, it will work in English.

To change the language, Web browser's language setting need to be changed. For example, in Internet Explorer version 6, go to the Tools menu and select Internet Options , Languages . Then ensure that the desired language is at the top of the list in the dialog box.
NOTE: To complete the change, Web browser needs to be restarted.

Password protect the Embedded Web Server

Follow these steps to password-protect the EWS:

  1. In the Embedded Web Server, go to the Security page , which can be found in the Settings tab.

  2. Enter any password in the New password field.

  3. Enter it again in the Confirm password field to guard against misspelling.

  4. Click Set password .

Now no-one will be able to perform the following actions with the Embedded Web Server without giving the password:

  • Manage print jobs in the queue (cancel, delete).

  • View previews of print jobs.

  • Delete stored jobs.

  • Clear accounting information.

  • Update the printer's firmware.

Request e-mail notification of specific error conditions

Following steps are used to request the e-mail notification of specific error conditions:

  1. In the Embedded Web Server, go to the E-mail server page , which can be found in the Settings tab, and ensure that the following fields are correctly filled in:
    • SMTP server : The IP address of the outgoing mail server (SMTP) that will process all Email messages from the printer. If the mail server requires authentication, E-mail notifications will not work.

    • Printer E-mail address : Each e-mail message sent by the printer must include a return address, which does not need to be a real, functional e-mail address, but it should be unique, so that recipients of the message can identify the printer that sent it.

  2. Go to the Notification page , which is also in the Settings tab.

  3. Click New to request new notifications (or Edit to edit notifications that have already been set up). Then fill in the e-mail addresses to which notifications should be sent, and select the incidents that should result in notification messages. Initially the most commonly-specified incidents are shown; to see all the possibilities, click Show all alerts .
