Android Tutorial Print Made Easy

After understanding this approach, printing will be painless for you forever.

Requirements:
- Any pdf file generation tool, I used HtmlToPdf lib.
- Any base64 converting tool, I used Base64EncodeDecodeImage lib.
- Rawbt printing service app, it is free and most downloaded app in play market specialized in printing.
- Don't forget to configure Rawbt app for first time only (run as a service + select printer + page width).

sub print(html as string)
                      
    'convert your print content to pdf file
    Dim phtmltopdf As PalmoHtmlToPdf
    phtmltopdf.Initialize("phtmltopdf")
    Dim pdffile As String="rawbtprint.pdf"
    If File.Exists(File.DirInternal,pdffile) Then File.Delete(File.DirInternal,pdffile)
    phtmltopdf.ConvertFromString(html,File.DirInternal,pdffile)
    Wait For phtmltopdf_Finished (Success As Boolean)
                      
    'send invisible print command to rawbt
    Dim Intent1 As Intent
    Intent1.Initialize2($"rawbt:data:application/pdf;base64,${Base64EncodeDecodeImage.Base64AnyFileToString(File.DirInternal,pdffile)}"$, 0)
    StartActivity(Intent1) 

end sub

Thanks.
