You could share it to another app uisng an intent

intent for beginner - messages between apps

Part 1 1- Intent is exactly a Specific Message between Android Apps. Building this message is simple in B4A: dim intent1 as intent 2- Any message (ie: intent) has a specific purpose to tell target app to do it, like SEND, CALL etc... So you initialize the intent with thats purposes ACTION...

B4X:

Dim Printer As Printer
    Printer.Initialize("")
    Printer.PrintWebView("job",WebView1)

I use this code and it shows me the default print page with a save to phone button as a pdf file, is there no way to share the file directly without saving it first?

What you want to achieve to share a (pdf) file without saving it to the phone, is actually saving a pdf out of sight and without the permission of the phone user. Because this possibility was abused by people with criminal intentions, this is no longer allowed by Android. OS. So here you run into a "Security First" measure.

I don't understand. You mean the file already in your phone?

Yes it would help if the goal that needs to be achieved is better described instead of asking a question about a possible means. The question is how is the pdf file made or where does the pdf come from, where does it go (like a server or another phone and if so how should the pdf file be stored there).
And as always a small example project is of course very helpful to help you alfaizdev.

I use the intent in one of my projects to hand images and files off to other apps. I first create the file and save this in the cache folder. After the intent has passed this off I clear the cache folder. This would work for you and no PDF file is retained.

Okay, this attached file shows printing WebView1 content with the ability to save it as a pdf, I want to share it directly as a pdf.

I have just shared this example.
I don't think it is possible to share a file if it is not exist in your phone unless it is on a cloud storage.

WebViewSharePDF

There are some examples on this forum for 1. saving Webview content as Bitmap, 2. creating PDF file using Printing library and 3. opening or sharing the PDF file to WhatsApp using FileProvider library but I don't see combination of these code so I have made a lot of trials and errors and...

Here's another solution

B4X:

    Dim phtmltopdf As PalmoHtmlToPdf
    phtmltopdf.Initialize("phtmltopdf")

    Private Provider As FileProvider
    Provider.Initialize
 
    phtmltopdf.ConvertFromString(htmlContent,Provider.SharedFolder,NameNew)
    Wait For  phtmltopdf_Finished (Success As Boolean)

        Dim in As Intent
        in.Initialize(in.ACTION_SEND, "شارك الملف")
        in.SetType("text/plain")
        in.PutExtra("android.intent.extra.STREAM", Provider.GetFileUri( NameNew))
        in.Flags = 1 'FLAG_GRANT_READ_URI_PERMISSION
        StartActivity(in)

You will need to modify this line :

B4X:

in.SetType("application/pdf")
