Silently Printing Your PDF

If you have ever had the need to give your end users a ‘Print’ button on the page then
read on.

Select the Form Field tool (see Figure 1.1), and draw a small button sized area on the page
(see Figure 1.2). When the Form Field dialog comes up give the Field a name (myButton) and
select ‘Button’ from the ‘Type’ list box (see Figure 1.3).

Print the Current Page only:

this.print(false,this.pageNum, this.pageNum,false);    

OR

Print from the current page to the end of the document:

this.print(false,this.pageNum, this.numPages,false);

The four parts of the javascript print command are:

  • True/False – Determines whether the ‘Print Dialog’ window is displayed.
  • Start Page Number
  • End Page Number
  • True/False – Determines whether the ‘Cancel’ print job dialog window is displayed.

You can type any valid page number in place of the ‘this.pageNum’ and ‘this.numPages’
statements.

Note: If you want to put some text on the ‘face’ of the button see below Figure 1.6 and
Figure 1.7.
