PrintJob

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 main thread of your app.

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 main thread of your app.

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 main thread of your app.

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.

An equivalence relation partitions the elements it operates on into equivalence classes; all the members of an equivalence class are equal to each other. Members of an equivalence class are substitutable for each other, at least for some purposes.

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 main thread of your app.

getAdvancedIntOption

public int getAdvancedIntOption (String key)

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

getAdvancedStringOption

public String getAdvancedStringOption (String key)

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

getDocument

public PrintDocument getDocument ()

Gets the printed document.
This method must be called from the main thread of your app.

getId

public PrintJobId getId ()

Gets the unique print job id.
This method must be called from the main thread of your app.

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.

getTag

public String getTag ()

Gets the print job tag.
This method must be called from the main thread of your app.

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 main thread of your app.

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 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 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.

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 main thread of your app.

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.
This method must be called from the main thread of your app.

isCompleted

public boolean isCompleted ()

Gets whether this print job is completed. Such a print job is successfully printed. This is a final state.
This method must be called from the main thread of your app.

isFailed

public 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.
This method must be called from the main thread of your app.

isQueued

public boolean isQueued ()

Gets whether this print job is queued. Such a print job is ready to be printed and can be started or cancelled.
This method must be called from the main thread of your app.

isStarted

public boolean isStarted ()

Gets whether this print job is started. Such a print job is being printed and can be completed or canceled or failed.
This method must be called from the main thread of your app.

setProgress

public void setProgress (float progress)

Sets the progress of this print job as a fraction of 1.
This method must be called from the main thread of your app.

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 main thread of your app.

setStatus

public void setStatus (int statusResId)

Sets the status of this print job as a string resource.

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 main thread of your app.

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 main thread of your app.

start

public boolean start ()

Starts the print job. You should call this method if isQueued() or isBlocked() returns true and you started resumed printing.

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