Instances of this class control the color state, paper size (media type), orientation, logical origin, print quality, and resolution of every page which uses the instance. Attribute names are compliant with the Internet Printing Protocol (IPP) 1.1 where possible. Attribute values are partially compliant where possible.
To use a method which takes an inner class type, pass a reference to one of the constant fields of the inner class. Client code cannot create new instances of the inner class types because none of those classes has a public constructor. For example, to set the color state to monochrome, use the following code:
import java.awt.PageAttributes;
public class MonochromeExample {
public void setMonochrome(PageAttributes pageAttributes) {
pageAttributes.setColor(PageAttributes.ColorType.MONOCHROME);
}
}
Every IPP attribute which supports an attributeName-default value
has a corresponding setattributeNameToDefault method.
Default value fields are not provided.
Two PageAttributes are equal if and only if each of their attributes are equal. Attributes of enumeration type are equal if and only if the fields refer to the same unique enumeration object. This means that an aliased media is equal to its underlying unique media. Printer resolutions are equal if and only if the feed resolution, cross feed resolution, and units are equal.
3 denotes dots per inch.
4 denotes dots per centimeter.wait methods.
The awakened thread will not be able to proceed until the current thread relinquishes the lock on this object. The awakened thread will compete in the usual manner with any other threads that might be actively competing to synchronize on this object; for example, the awakened thread enjoys no reliable privilege or disadvantage in being the next thread to lock this object.
This method should only be called by a thread that is the owner of this object's monitor. A thread becomes the owner of the object's monitor in one of three ways:
synchronized statement
that synchronizes on the object.
Class, by executing a
synchronized static method of that class.
Only one thread at a time can own an object's monitor.

The awakened threads will not be able to proceed until the current thread relinquishes the lock on this object. The awakened threads will compete in the usual manner with any other threads that might be actively competing to synchronize on this object; for example, the awakened threads enjoy no reliable privilege or disadvantage in being the next thread to lock this object.
This method should only be called by a thread that is the owner

description of the ways in which a thread can become the owner of
a monitor.
3 denotes portrait. Specifying 4
denotes landscape. Specifying any other value will generate an
IllegalArgumentException. Not specifying the property is equivalent
to calling setOrientationRequested(OrientationRequestedType.PORTRAIT).72.3 denotes dots per inch. 4
denotes dots per centimeter. Note that the 1.1 printing implementation
(Toolkit.getPrintJob) requires that the feed and cross feed resolutions
be the same. Not specifying the property is equivalent to calling
setPrinterResolution(72).3 denotes draft. Specifying 4
denotes normal. Specifying 5 denotes high. Specifying
any other value will generate an IllegalArgumentException. Not
specifying the property is equivalent to calling
setPrintQuality(PrintQualityType.NORMAL).
The current thread must own this object's monitor. The thread
releases ownership of this monitor and waits until another thread
notifies threads waiting on this object's monitor to wake up
either through a call to the notify method or the
notifyAll method. The thread then waits until it can
re-obtain ownership of the monitor and resumes execution.
As in the one argument version, interrupts and spurious wakeups are possible, and this method should always be used in a loop:
synchronized (obj) {
while (<condition does not hold>)
obj.wait();
... // Perform action appropriate to condition
}
This method should only be called by a thread that is the owner
of this object's monitor. See the notify method for a
description of the ways in which a thread can become the owner of
a monitor.The current thread must own this object's monitor.
This method causes the current thread (call it T) to place itself in the wait set for this object and then to relinquish any and all synchronization claims on this object. Thread T becomes disabled for thread scheduling purposes and lies dormant until one of four things happens:
A thread can also wake up without being notified, interrupted, or timing out, a so-called spurious wakeup. While this will rarely occur in practice, applications must guard against it by testing for the condition that should have caused the thread to be awakened, and continuing to wait if the condition is not satisfied. In other words, waits should always occur in loops, like this one:
synchronized (obj) {
while (<condition does not hold>)
obj.wait(timeout);
... // Perform action appropriate to condition
}

2000), or Item 50 in Joshua Bloch's "Effective Java Programming
Language Guide" (Addison-Wesley, 2001).
If the current thread is interrupted by another thread while it is waiting, then an InterruptedException is thrown. This exception is not thrown until the lock status of this object has been restored as described above.
Note that the wait method, as it places the current thread into the wait set for this object, unlocks only this object; any other objects on which the current thread may be synchronized remain locked while the thread waits.
This method should only be called by a thread that is the owner
of this object's monitor. See the notify method for a
description of the ways in which a thread can become the owner of
a monitor.
This method is similar to the wait method of one
argument, but it allows finer control over the amount of time to
wait for a notification before giving up. The amount of real time,
measured in nanoseconds, is given by:
1000000*timeout+nanos
In all other respects, this method does the same thing as the method of one argument. In particular, wait(0, 0) means the same thing as wait(0).
The current thread must own this object's monitor. The thread releases ownership of this monitor and waits until either of the following two conditions has occurred:
notify method
or the notifyAll method.
timeout
milliseconds plus nanos nanoseconds arguments, has
elapsed.
The thread then waits until it can re-obtain ownership of the monitor and resumes execution.
As in the one argument version, interrupts and spurious wakeups are possible, and this method should always be used in a loop:
synchronized (obj) {
while (<condition does not hold>)
obj.wait(timeout, nanos);
... // Perform action appropriate to condition
}
This method should only be called by a thread that is the owner
of this object's monitor. See the notify method for a
description of the ways in which a thread can become the owner of
a monitor.
