Automate create Statement of Account and print to PDF

Troubleshooting
#1

Hi there,

I wish to get some help.

I am trying to automate printing to PDF of Statement of Account. I am stuck at the new print dialog window. The Robocode Lab has the last task running, in waiting for the print operation to complete.

The attached is the screen capture and the output rst code.

Thanks,
Yew

Hi @yewengehoe! Welcome to the Forum :wave:

Is your problem that save is not pressed on that print dialog ?

Your task structure seems a bit odd to me. You have multiple tasks for this one thing that you are trying to do ? What is the order of actions you need to execute ?

What is the main task, is it Retrieve the AR data for the month and export it as a PDF ? You could change all other tasks into keywords… and then probably have something like …

Retrieve the AR data for the month and export it as a PDF
    Open The Wave Customer Statement URL
    Log In
    Fill The Form Using The Data From The Excel File
    Handle Printing

If the problem is about clicking that Save button AND you are working with Windows OS then you can include RPA.Desktop.Windows and grab that save button as savebutton.png and use the following keyword for clicking it…

Hi @mika ! Thank you! :smiley:

I am using Linux OS.

Sorry about the messy task structure, please ignore the last 2 Tasks cells.

I am trying single or a few tasks cell by cell. I have reached the stage to call out the print dialog windows. I am stuck at asking the robot to click on Save button.

After calling out the print window, do I need to tell the robot to focus on it, such as running code:
Go to chrome://print ?

After running this task below, the robot will be waiting for something to complete. When I manually click cancel in the print window, it stop and show some error messages.

code:
*** Tasks ***
Select Print from Dropdown Menu
Click Element CSS:.wv-dropdown__menu__link.print-link

The attached below are screenshot images of my manual operation.

The print dialog window is still a chrome window. The Save to PDF dialog window is Linux OS window.

Thank you again.

Hi @mika,

I capture the image where I am stuck.

In the print dialog window, if I click Save and Save or Cancel to complete the process, the task will be completed.

@yewengehoe That print dialog is system dialog you are trying to click and you can’t do that with selenium.

So you can select Print from the dropdown menu, but after that you need to use desktop automation to click Save (that is how I see your problem).

We don’t atm have support for Linux desktop but I have been trying Linux automation to solve your case using image recognition.

If you want to try this “hackish” solution then try my example https://github.com/robocorp/robot-playground/tree/master/desktop

So you need to install that package pyautogui and copy paste desktop.py to your tasks folder, import it as a library like in the example.robot. Then you can try keywords click image and press_key. Grab that save button as an image to click on.

Hi @mika,

Should I screenshot the “Save” button as PNG image, as this Save ? If so, where should I save it to in the project/package folder?

About the image recognition and desktop.py code, is there a tutorial to learn more about it? Sorry that I am quite new to Python, Selenium, programming in general.

Thank you for your guidance! :smile:

To begin with you can place that Save button image into your tasks folder so that you can easily try how things work. That click_image takes the image as filepath so that can be placed in more convient place, for example resources after you have verified that this approach works.

Please keep me updated how your task is progressing. I hope that you can manage to complete it :+1:

Some information sites.

Not sure if this helps, but note that when you open the print dialog for PDF output, a PDF is already being generated at this point in time (which is used for the preview).

Maybe it’s even generated before that on another occasion (I don’t know how Wave works and how it’s producing the previews it’s showing in side the web application. If they use pdfjs, it might already be a PDF at that time as well? Maybe something to check).
