## Public methods

### block

    public boolean block (String reason)

Blocks the print job. You should call this method if `isStarted()` returns true and you need to block the print job. For example, the user has to add some paper to continue printing. To resume the print job call `start()`. To change the reason call `setStatus(java.lang.CharSequence)`.
This method must be called from the Looper#getMainLooper() of your app.

Parameters
`reason` | `String`: The human readable, short, and translated reason why the print job is blocked. This value may be `null`.

Returns
`boolean` | Whether the job was blocked.

See also:

- `isStarted()`
- `isBlocked()`

### cancel

    public boolean cancel ()

Cancels the print job. You should call this method if `isQueued()` or `or #isBlocked()` returns true and you canceled the print job as a response to a call to `PrintService#onRequestCancelPrintJob(PrintJob)`.
This method must be called from the Looper#getMainLooper() of your app.

Returns
`boolean` | Whether the job is canceled.

See also:

- `isStarted()`
- `isQueued()`
- `isBlocked()`

### complete

    public boolean complete ()

Completes the print job. You should call this method if `isStarted()` returns true and you are done printing.
This method must be called from the Looper#getMainLooper() of your app.

Returns
`boolean` | Whether the job as completed.

See also:

- `isStarted()`

### equals

    public boolean equals (Object obj)

Indicates whether some other object is "equal to" this one.

The `equals` method implements an equivalence relation on non-null object references:

- It is reflexive: for any non-null reference value `x`, `x.equals(x)` should return `true`.
- It is symmetric: for any non-null reference values `x` and `y`, `x.equals(y)` should return `true` if and only if `y.equals(x)` returns `true`.
- It is transitive: for any non-null reference values `x`, `y`, and `z`, if `x.equals(y)` returns `true` and `y.equals(z)` returns `true`, then `x.equals(z)` should return `true`.
- It is consistent: for any non-null reference values `x` and `y`, multiple invocations of `x.equals(y)` consistently return `true` or consistently return `false`, provided no information used in `equals` comparisons on the objects is modified.
- For any non-null reference value `x`, `x.equals(null)` should return `false`.

The `equals` method for class `Object` implements the most discriminating possible equivalence relation on objects; that is, for any non-null reference values `x` and `y`, this method returns `true` if and only if `x` and `y` refer to the same object (`x == y` has the value `true`).

Note that it is generally necessary to override the `hashCode` method whenever this method is overridden, so as to maintain the general contract for the `hashCode` method, which states that equal objects must have equal hash codes.

Parameters
`obj` | `Object`: the reference object with which to compare.

Returns
`boolean` | `true` if this object is the same as the obj argument; `false` otherwise.

### fail

    public boolean fail (String error)

Fails the print job. You should call this method if `isQueued()` or `isStarted()` or `isBlocked()` returns true you failed while printing.
This method must be called from the Looper#getMainLooper() of your app.

Parameters
`error` | `String`: The human readable, short, and translated reason for the failure. This value may be `null`.

Returns
`boolean` | Whether the job was failed.

See also:

- `isQueued()`
- `isStarted()`
- `isBlocked()`

### getAdvancedIntOption

    public int getAdvancedIntOption (String key)

Gets the value of an advanced (printer specific) print option.
This method must be called from the Looper#getMainLooper() of your app.

Parameters
`key` | `String`: The option key.

Returns
`int` | The option value.

### getAdvancedStringOption

    public String getAdvancedStringOption (String key)

Gets the value of an advanced (printer specific) print option.
This method must be called from the Looper#getMainLooper() of your app.

Parameters
`key` | `String`: The option key.

Returns
`String` | The option value.

### getDocument

    public PrintDocument getDocument ()

Gets the printed document.
This method must be called from the Looper#getMainLooper() of your app.

Returns
`PrintDocument` | The document. This value cannot be `null`.

### getId

    public PrintJobId getId ()

Gets the unique print job id.
This method must be called from the Looper#getMainLooper() of your app.

Returns
`PrintJobId` | The id.

### getInfo

    public PrintJobInfo getInfo ()

Gets the `PrintJobInfo` that describes this job.

Node:The returned info object is a snapshot of the current print job state. Every call to this method returns a fresh info object that reflects the current print job state.

This method must be called from the Looper#getMainLooper() of your app.

Returns
`PrintJobInfo` | The print job info. This value cannot be `null`.

### getTag

    public String getTag ()

Gets the print job tag.
This method must be called from the Looper#getMainLooper() of your app.

Returns
`String` | The tag or null.

See also:

- `setTag(String)`

### hasAdvancedOption

    public boolean hasAdvancedOption (String key)

Gets whether this job has a given advanced (printer specific) print option.
This method must be called from the Looper#getMainLooper() of your app.

Parameters
`key` | `String`: The option key.

Returns
`boolean` | Whether the option is present.

### hashCode

    public int hashCode ()

Returns a hash code value for the object. This method is supported for the benefit of hash tables such as those provided by `HashMap`.

The general contract of `hashCode` is:

- Whenever it is invoked on the same object more than once during an execution of a Java application, the `hashCode` method must consistently return the same integer, provided no information used in `equals` comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
- If two objects are equal according to the `equals(Object)` method, then calling the `hashCode` method on each of the two objects must produce the same integer result.
- It is not required that if two objects are unequal according to the `equals(java.lang.Object)` method, then calling the `hashCode` method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.

As much as is reasonably practical, the hashCode method defined by class `Object` does return distinct integers for distinct objects. (This is typically implemented by converting the internal address of the object into an integer, but this implementation technique is not required by the Java™ programming language.)

Returns
`int` | a hash code value for this object.

### isBlocked

    public boolean isBlocked ()

Gets whether this print job is blocked. Such a print job is halted due to an abnormal condition and can be started or canceled or failed.
This method must be called from the Looper#getMainLooper() of your app.

Returns
`boolean` | Whether the print job is blocked.

See also:

- `start()`
- `cancel()`
- `fail(String)`

### isCancelled

    public boolean isCancelled ()

Gets whether this print job is cancelled. Such a print job was cancelled as a result of a user request. This is a final state.

Returns
`boolean` | Whether the print job is cancelled.

See also:

- `cancel()`

Parameters
`progress` | `float`: The new progress Value is between 0.0 and 1.0 inclusive

### setStatus

    public void setStatus (CharSequence status)

Sets the status of this print job. This should be a human readable, short, and translated description of the current state of the print job.

This overrides any previously set status set via `setStatus(java.lang.CharSequence)`, `setStatus(int)`, `block(java.lang.String)`, or `fail(java.lang.String)`,
This method must be called from the Looper#getMainLooper() of your app.

Parameters
`status` | `CharSequence`: The new status. If null the status will be empty. This value may be `null`.

### setStatus

### setTag

    public boolean setTag (String tag)

Sets a tag that is valid in the context of a `PrintService` and is not interpreted by the system. For example, a print service may set as a tag the key of the print job returned by a remote print server, if the printing is off handed to a cloud based service.
This method must be called from the Looper#getMainLooper() of your app.

Parameters
`tag` | `String`: The tag. This value cannot be `null`.

This resets the print status to null. Set the new status by using `setStatus(int)`.

This method must be called from the Looper#getMainLooper() of your app.

Returns
`boolean` | Whether the job was started.
