This class represents a print job from the perspective of a print service. It provides APIs for observing the print job state and performing operations on the print job.

Note: All methods of this class must be invoked on the main application thread.

Public methods

block

Added in API level 19
boolean block (String reason)

Blocks the print job. You should call this method if isStarted() or isBlocked() 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().

Parameters
reason String
Returns
boolean Whether the job was blocked.

See also:

cancel

Added in API level 19
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 onRequestCancelPrintJob(PrintJob).

Returns
boolean Whether the job is canceled.

See also:

complete

Added in API level 19
boolean complete ()

Completes the print job. You should call this method if isStarted() returns true and you are done printing.

Returns
boolean Whether the job as completed.

See also:

equals

Added in API level 19
boolean equals (Object obj)

Compares this instance with the specified object and indicates if they are equal. In order to be equal, o must represent the same object as this instance using a class-specific comparison. The general contract is that this comparison should be reflexive, symmetric, and transitive. Also, no object reference other than null is equal to null.

The default implementation returns true only if this == o. See Writing a correct equals method if you intend implementing your own equals method.

The general contract for the equals and hashCode() methods is that if equals returns true for any two objects, then hashCode() must return the same value for these objects. This means that subclasses of Object usually override either both methods or neither of them.

Parameters
obj Object: the object to compare this instance with.
Returns
boolean true if the specified object is equal to this Object; false otherwise.

fail

Added in API level 19
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.

Parameters
error String: The human readable, short, and translated reason for the failure.
Returns
boolean Whether the job was failed.

See also:

getAdvancedIntOption

Added in API level 19
int getAdvancedIntOption (String key)

Gets the value of an advanced (printer specific) print option.

Parameters
key String: The option key.
Returns
int The option value.

getAdvancedStringOption

Added in API level 19
String getAdvancedStringOption (String key)

Gets the value of an advanced (printer specific) print option.

Parameters
key String: The option key.
Returns
String The option value.

getDocument

Added in API level 19
PrintDocument getDocument ()

Gets the printed document.

Returns
PrintDocument The document.

getId

Added in API level 19
PrintJobId getId ()

Gets the unique print job id.

Returns
PrintJobId The id.

getInfo

Added in API level 19
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.

Returns
PrintJobInfo The print job info.

getTag

Added in API level 19
String getTag ()

Gets the print job tag.

Returns
String The tag or null.

See also:

hasAdvancedOption

Added in API level 19
boolean hasAdvancedOption (String key)

Gets whether this job has a given advanced (printer specific) print option.

Parameters
key String: The option key.
Returns
boolean Whether the option is present.

hashCode

Added in API level 19
int hashCode ()

Returns an integer hash code for this object. By contract, any two objects for which equals(Object) returns true must return the same hash code value. This means that subclasses of Object usually override both methods or neither method.

Note that hash values must not change over time unless information used in equals comparisons also changes.

See Writing a correct hashCode method if you intend implementing your own hashCode method.

Returns
int this object's hash code.

isBlocked

Added in API level 19
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.

Returns
boolean Whether the print job is blocked.

See also:

isCancelled

Added in API level 19
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:

isCompleted

Added in API level 19
boolean isCompleted ()

Gets whether this print job is completed. Such a print job is successfully printed. This is a final state.

Returns
boolean Whether the print job is completed.

See also:

isFailed

Added in API level 19
boolean isFailed ()

Gets whether this print job is failed. Such a print job is not successfully printed due to an error. This is a final state.

Returns
boolean Whether the print job is failed.

See also:

isQueued

Added in API level 19
boolean isQueued ()

Gets whether this print job is queued. Such a print job is ready to be printed and can be started or cancelled.

Returns
boolean Whether the print job is queued.

See also:

isStarted

Added in API level 19
boolean isStarted ()

Gets whether this print job is started. Such a print job is being printed and can be completed or canceled or failed.

Returns
boolean Whether the print job is started.

See also:

setTag

Added in API level 19
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.

Parameters
tag String: The tag.
Returns
boolean True if the tag was set, false otherwise.
