Hi all,

I am using google image charts for a reporting app.
I am using imagecharts for that.
I successfully getting the url of the image chart using getImageUrl()
method.
I have passed this URL to a backend servelet. Now what I want is to
print this image in the client's printer.

How can I do it?
Please someone help me.

Since you successfully got the image, sending it to browser print is not related to this forum, sorry.

Hi,

This is not related to Google charts. You can try to make a pdf from the image (try itext), then embed print script in the pdf (AcroJs).

You only need to know the printer name (works also with network printers, use full path as shown in pdf reader) on the client. Note that for security reasons when printing automatically a confirmation pops up if you would like to print. You can bypass this by installing trusted print script on the client side (for example in C:\Program Files\Adobe\Reader 10.0\Reader\Javascripts).

It is not perfect but it gets the job done.

HTH,

Ps, Adobe made fix in 10.1.3 for grey empty page problem in pdf with IE. It is wise to upgrade to this version.
