Ubuntu - Modifying Printer Properties

You can modify the properties of any printer on the system, whether Ubuntu automatically created it or you manually created it. If you double-click the icon for the printer you want to configure.

The window on the left contains five main properties groups that contain printer information you can modify. The main groups are
• Settings
• Policies
• Access Control
• Printer Options
• Job Options
Some printers contain a sixth group for setting specific options for the printer.

The Settings group provides some basic settings you can change for the printer. From here, you can change the description and location tags for the printer, the URI of the printer, and the PPD file used for the printer. There are also three other buttons that you can use:

• Print Test Page: Provides an easy way for you to test whether the printer and PPD file are working properly.

• Print Self-Test Page: Some printers support an internal self-test page. If your printer supports that feature, this button will be enabled.

• Clean Print Heads: Some printers support an external command to clean the print heads. If your printer supports that feature, this button will be enabled. That covers the general settings for the printer. The other groups provide more advanced settings.

The Policies group contains three separate sections. The State section allows you to control the state of the printer:
• Enabled: Lets you take the printer offline if there’s a problem.
• Accepting Jobs: Allows you to temporarily suspend processing print jobs.
• Shared: Allows you to set whether the printer is a shared resource on the network.

There are four policies (or rules) that control printer behavior. Two of the policies control banner pages for print jobs; the other two control how the printer operates.

There are two operation policies that you can set:

• Error Policy: Determines how the printer reacts to an error in the printing process.
The choices are Abort-Job (giving up on printing the job), Retry-Job (trying again after manual intervention), or Stop-Printer (preventing all other print jobs from printing). The default value is to retry the job because the problem most likely can be resolved with an easy fix, such as turning the printer on or setting it as online.

• Operation Policy: Determines the mode the printer runs in. At this time, the only setting is default.

Banner pages allow you to print a special page describing the print job. The Starting Banner page prints out before the print job. This option allows you to print a cover sheet for the print job. Theoretically, it’s supposed to provide some privacy, blocking people from seeing the first print page on the printer, but, really, who wouldn’t just look under the banner page? There are several banner pages you can choose from.

The Ending Banner page allows you to print a page that signifies the end of the print job. If you’re in a high-volume printing environment, using a starting or ending banner helps keep everyone’s print jobs separate. In a workstation environment, it’s pretty much a waste of paper. The default is to not print either of the banner pages.

Access Control
The Access Control group provides a method for you to restrict access to the printer. There are two ways to do this. First, you can list every user account that the server will prevent from using the printer. This option means that any user not on the list can print and that any user on the list can’t print.

The second method is to list the user accounts that are allowed to use the printer. This option means that only the users on the list can print. Obviously, which method you choose depends on whether you have more people you want to allow to print or to restrict from printing.

Be careful when setting this feature. Notice how the two radio buttons are labeled:
• Allow printing for everyone except these users.
• Deny printing for everyone except these users.

If you click the Allow Printing radio button, the user accounts you list will be denied access to the printer—and vice versa for the Deny Printing radio button. That’s just a bit backward, if you ask me!

Printer Options
The Printer Options group allows you to set some physical properties for the printer. The properties available for you to modify are based on information provided by the individual printer’s PPD file and depend on the physical characteristics of the printer. These properties are divided into separate categories, depending on the printer’s capabilities.

The General settings handle properties such as types of paper the printer can handle,
print qualities it can produce, and number and types of input trays. You can force the
printer server to request a specific paper size for all print jobs or to request which paper
tray to take paper from.
The Printout Mode settings control the default print quality used by the printer. Again,
these settings depend on the capabilities of the particular printer, but usually there’s a
range of dots per inch (dpi) and color settings to choose from.

Job Options
Finally, the Job Options tab allows you to set the default properties for print jobs sent to the printer. When you request an application to send something to the printer, a standard GNOME Print dialog box appears.

You can select several printing properties for the specific print job, such as whether to print in landscape mode, how many copies of the document to print, the paper size to use, and so on. If you prefer to use any of these settings by default, you can set them in the Job Options tab. Many more print job options can be specified. The job options are divided into four sections:

• Common Options: Sets common printer options, such as number of copies, page orientation, and number of printed sides (for duplex printing).

• Image Options: Sets imaging options such as scaling and hue adjustment.

• Text Options: Sets features that affect the printed text, such as characters per inch, lines per inch, and margins.

• Advanced Options: Allows you to set options available for a specific printer. The complete list of options appears within the Printer Configuration Properties window.

If you decide to revert to the default setting for an option, click the Reset button, and the option will return to the default value.
