Printing with DocIO UWP

[Romane Donnet]

Hi guys!

I just wanted to know if someone has a workaround to print generated Docx directly or via pdf or any other solutions from an UWP app?

Seems that doc.renderasImage isn't in UWP library

romane

Hi Romane,

Thank you for using Syncfusion products.

You can use SfRichTextBoxAdv control to load Word documents. Using GetPageAsImageAsync() method, you can retrieve the page in SfRichTextBoxAdv as BitmapImage by specifying the page number. You can then print these bitmap images using PrintManager. We have prepared a sample to demonstrate the same. Please do find the sample from below link.

Please let us know if you have any other queries.

Hi Sarath!

Thanks for your quick answer!

Your sample seems very promising but when I tested it, it doesn't seems to work... after I re-linked the references to syncfusion UWP docIO and the other then the projets achived to compile. I started it and seemed to work at first. Then I double clicked on a docx file generated on Office 365 Word but the "await richTextBoxAdv.LoadAsync(stgFile);" method doesn't seems to work :( It doesn't bug or breakpoint it just says nothing and doesnt display anything on the screen. When i try to print it says that the pdf fil is corrupt and with a normal printer doesnt work as well.

Hi Romane,

Please find the modified sample to illustrate loading word documents into SfRichTextBoxAdv control and printing contents from the following link.

Sample Link:
Sample

If you have installed Essential Studio for Universal Windows in your machine, you can refer our Syncfusion UWP assemblies from following location.

Assembly Reference:
$system drive: \Program Files\Syncfusion\Essential Studio\version \Assemblies for Universal Windows\10.0\

Eg:
C:\Program Files\Syncfusion\Essential Studio\13.3.0.7 \Assemblies for Universal Windows\10.0\

If the problem still persists, please share us the input document so that we can investigate on it further and provide you with proper solution.

Hi!

Your sample works your were right about the assemblies! I was importing them from :

C:\Program Files (x86)\Syncfusion\Essential Studio\13.3.0.7\Universal Windows\10.0\SDK\References\CommonConfiguration\neutral

As soon as i have imported from :

C:\Program Files\Syncfusion\Essential Studio\13.3.0.7 \Assemblies for Universal Windows\10.0\

It started to work!!

Next question :

I saw that the generation was in few steps : Selecting, loading into richtextBox, generating bitmap, printing.

1. My concerne is that the bitmaps generated are really ugly!! 

2. Is it mendatory to have a print preview? can't i just launch the printmanager without it?

3. I'm trying to make a silent print a the end for my customer. I mean he click on a button that takes a template modifies it and direclty print it without prompting anything on UWP do you think its possible?

My document generation works perfectly! Thanks to you! I have a beautiful Word document generated really fast! 2 secondes for 100 pages!! But i'm wondering why is it so difficult to just print a word document from an app...

I know for fact that you can't call system commands anymore in UWP like "winword.exe myfile.doc /p /q" to print silently something but isn't there any workaround?

Thanks a lot!!!!

Hi Romane,

Thank you for your update.

We are glad to hear that the sample is working fine at your end.

Regarding “Query 1”:
At this moment, there is no direct support for printing contents from SfRichTextBoxAdv control in Universal Windows Platform and printing is achieved only by BitmapImage of pages in SfRichTextBoxAdv control. Direct printing of contents will enhance the image quality. We have already logged this requirement as a feature request and this will be implemented in our next Essential Studio main release 2015 Volume 4. We request to check our website periodically for feature related updates.

Regarding “Query 2, 3 & 4”:
It is mandatory to show print preview and it is not possible to print directly without prompting Print Preview UI in Universal Windows apps. For more information, kindly refer the MSDN forum from following link.

We have added it to our feature request list and it will be implemented in any of our upcoming releases. However, we have created a sample to convert an Excel file into PDF in UWP platform using web services which can be downloaded from the below link.

Hi,

I tried this sample and it works well with le excel document you provide, but when I try with my excel document, the pdf still looks like the older one and I don't understand why.

Hi Charles, 

 

We need to have the actual Excel file that is causing the issue as to investigate further on this, as we suspect that the issue raises only in the particular document. You can also create an incident from Direct-Trac to share your Excel document for further investigation. The documents shared will not be disclosed and used only for testing purpose.

Hi,

I tried with 3 differents excel document and I changed the document name inside " assembly.GetManifestResourceStream() " nothing append.

And if I keep ExceltoPDF.xlsx inside the function and rename my document ExceltoPDF.xlsx, the PDF doesn't change.

The only difference I see between your document and mine is the size, your document is 36KB and mines are 6032KB or 531KB.

Regards,

Charles.

Hi,

Sorry for bothering you again, I am currently looking for printing word document and I use this sample but the quality is very bad because It use images.

I want to know if there is a way to do it differently.

And if it's possible to direct print to pdf.

Regards, 

Charles

Hi Charles, 

  

Thank you for updating us. 

  

We suspect that the issue might be raised due to the input document is not added into embedded resource. The input document should be added into embedded resource in UWP application to manipulate it. Please refer the following screenshot to achieve this.

We have also modified the sample for this which can be downloaded from the following location.

Right now the pdf is print as an image and I don't want that.

Thanks you again,

Hi,

I just wanted to know if it was possible to do the same ( print word document ) but with an Excel document ?

I know that SfRichTextBoxAdv can't open Excel document but maybe an other control could and would allow me to print it ?

Regards,

Charles

Hi Charles,

Thank you for your update.

Our SfSpreadsheet control allows you to view/edit the excel documents. At present our SfSpreadSheet control does not have printing support. We have already logged this requirement as feature request. We will implement these features in any of our forthcoming releases. We usually have a timeframe of at least three months between releases. The feature implementation would also greatly depend on the factors like product design, code compatibility and complexity. We request you to visit our website periodically for feature related updates.
