I'm assuming Windows has APIs to tell the printer to print out a PDF

ShellExecute + $SHEX_PRINT ("print") = Prints the document file specified. If "filename" is not a document file, the function will fail

but you must have intaled program like PDFReader or any other.

Surely there's another way. How do programs like PDF reader do it?

AFAIK Printers can directly accept postscript documents (which are very also valid PDF documents) so there must be a way to tell a printer to print the file directly, perhaps after some post-processing.

And I guess you can also go the route of automating the print dialog in Chrome, but you'll have to automate it directly, window.print will not help you here.

I was hoping in sending CTRL+P some how via WD UDF.

yes, usually all solutions for printing PDF needs some kind of third party software.
I mean I never found direct windows solution.
The easies way is

For this reason we are trying to make it possible to print directly from browsers to printer device, with full automatization.

Doesn't that do the same thing as calling window.print()? i.e. opening the print dialog

This will be a hard/impossible task to do with cross-browser support, so I wish you the best of luck. At-least Chrome is allowing you to attach the print window with WD for automation

but when I commented:

;~  _WD_ExecuteScript($sSession, 'window.print()', Default, True)

and manually used CTRL+P

then it founds that correct attach method is:

_WD_Attach($sSession, 'chrome://print/', 'url')

I know.

I have to check if the same code works with Edge and Opera.

I wonder:
How to use JS to get element identifier the same as is returned by _WD_FindElement() ?

Can't scripts return elements which are translated into the element identifiers by the WD?

return document.body;

 

Edited August 2, 2022 by TheDcoder

[mLipok]

Local $sWebDriver_ElementID =_WD_ExecuteScript($sSession, "return window.document.body;", Default, Default, $_WD_JSON_Element)
                MsgBox(0, "$sWebDriver_ElementID", $sWebDriver_ElementID)

Thanks.

Hi Dan,

is it possible to click on a button identified with src="..." where src contains a special string to search for? I cannot use the XPath because it changes sometimes and there are many similiar ones which differ just in one number (and that changes). But I can find a string in each src="" that is unique.

Example:

<img id="content-form:favorites:1:fav-image" src="/portal/images/icons/vu/icon_german.png.xhtml" alt="" style="width: 126px; height: 96px; position: relative;" class="ui-draggable ui-draggable-handle ui-droppable">

<img id="content-form:favorites:5:fav-image" src="/portal/images/icons/vu/icon_greek.png.xhtml" alt="" style="width: 126px; height: 96px; position: relative;" class="ui-draggable ui-draggable-handle ui-droppable">
 

And I want to click on the Button that contains src="... german ...". I cannot use the :1: because next time it could be :6: or any other number.

Thanks for your help!

@HJLYou should be able to find an xpath or CSS selector that will suit your needs. Something like --

$sXpath = "//img[contains(@src, "<your unique string here>")]

Also, you mentioned a button, but you are targeting an image. Be sure that you have identified the correct element to click.

[HJL]

It is an image, you are right. 😉

try this:

Local $sElement = _WD_FindElement($sSession, $_WD_LOCATOR_ByCSSSelector, "img[src*='icon_german' AND src*='png' AND src*='xhtml']")
_WD_ElementAction($sSession, $sElement, 'CLICK')

For more information take a look here:
https://developer.mozilla.org/en-US/docs/Web/CSS/Attribute_selectors

 

You can also use more advanced function: _WD_GetElementByRegEx()

@mLipok
When using browser console, it returned the belowmentioned result for me.

window.location.href
'chrome://print'

This correct attach method works for me as well.

_WD_Attach($sSession, 'chrome://print/', 'url')

Question here is (instead of navigating to chrome://print on my own) how do I get to this Print Dialog pop-up window and execute all the functions I coded to interact with this Print Dialog pop-up window?

I was then able to interact with the elements on this Chrome Print Dialog pop-up! 🙂
Some of them include:

;Success
    _WD_ChromePrintDestination($sSession, 'Save as PDF') ; Change to Brother MFC/TSC-TA210 on real deployment
    _WD_ChromePrintMoreSettings($sSession) ; Expand More Settings section
    _WD_ChromePrintPaperSize($sSession, 'A5') ; A5 (Invoices) / Label(medicine labels) / A4 (Documents)
    _WD_ChromePrintScalingType($sSession, 'Customised')
    _WD_ChromePrintScalePercent($sSession, '75') ; 75 (Invoices) / 100 (Labels)

I used Send("^p") in place of the manual Ctrl+P 🙂
I know, it's a 'dirty' way of invoking. It was just to test.

Thank you all who's been very helpful and taking an interest to this little project of mine.
With the functions that we've co-written and figuring out attaching to the Chrome Print Dialog, that's attaching to a self-invoked Print Dialog, off a session that's started by the code and navigated to URL, etc.

How could I attach to a Print Dialog that's being invoked by the end-user?
From a CRM website (when they select the Print icon off the site).
The flow is as such:
The end-user uses a cloud-based CRM and when they initiate to print invoices/labels, the CRM website:
1) Opens a new tab with a image render of the invoice or label
2) Calls the famous (Ctrl+P) Chrome's Print Preview Dialogue whose window pops up on top of this new tab

I tried manually invoking this Print Dialog from the CRM website (instead of sending Ctrl-P from the code), it could not find it (No match [8])

Maybe, I'll find some time tomorrow to draw up the algorithm flowchart of this little project to illustrate things better. That could give a better idea.

Thanks once again.

Thanks for waiting. I'll attach the flowchart here as PDF. 🙂 

I've managed to code the area marked by green dotted lines - - - "Completed"

Struggling with the SetupChrome() to startup, connecting to a running browser instance and utilizing an existing user profile.
- Running browser instance = tab where the CMS website is open
- Or if it isn't necessary, running browser instance = directly to the Print Dialog pop-up window when the CMS invokes it.

And WD_Attach to the Print Dialog invoked by the CMS.

The GUI, I was thinking of it more for later.

If it is too complicated, it could also be replaced by an assigned HotKey, which waits for a HotKey pressed each time, executes codes, then loops and return to waiting for the next HotKey press trigger?

Thank you.

CMS Printing Automation Flowchart.pdf

[mLipok]

So as far as I understand the situation:
When somebody click "Print Invoice" on the main TAB then CMS opens new TAB and this means that your main TAB is not blocked.

Does this also means that your AutoIt WebDriver automation also is not blocked when the new TAB appears (I mean after AutoIt script click "Print Invoice" ) ?

btw.
Awesome flowchart PDF. How did you do it?

edit:
please read also * Please remember: "AutoIt"..... *

hello,

 

i break my mind with the webdriver, i need your help.

what is the alternatives:

1.StringInStr

2._IEPropertyGet

3._IEGetObjById

4._IELoadWait

5._IEBodyReadHTML

6._IEAction($oIE, "selectall") , _IEAction($oIE, "copy")

7._IEFormElementSetValue

 

thanks!!

Take a look at our WD wiki topic.

There is section about migrating from IE ro WD
