    Hello, pre-purchase question:

    Can i custom design the stamp? my company has rounded stamps with company logo, and manual customer details inputted into it. Can i use this plugin to create custom stamps based on customer info such as name, email, …etc?

    Cheers

      If you use text stamp option, you can dynamically stamp customer details in text format, how for there is also an option to stamp a pre-designed image. However, to create the stamp image dynamically, there will require additional customization.

    Purchased the PDF Stamper and uploaded the zip file via the plugin add- then activated the plugin. Now, I cannot see the the plugin in my WordPress dashboard. I can find it under plugins but there are no additional setting links, etc associated with it.

      PDF stamper will work for only individual PDF attachment, not for zipped PDF files. When you have multiple pdf files with a package, and needs to be stamped, please use only [file_list] tag with thw page template, and skip [download_link] tag.

    Hello,

    does it requires Woocommerce or a buy process or does it simply apply watermark to .pdfs downloads created with Download Manager with users account details?

    Thank you

    8 years
    1. Shahjada

      None of the items at http://www.wpdownloadmanager.com have any dependency on Woocommerce. PDF Stamper is also developed specially for download manager files. Yes, It will apply a watermark to .pdfs downloads created with Download Manager and you can control the watermark text from settings page..

    In the documentation it says it “is specially developed for WordPress Download Manager” — is this a plugin, or just the generic WordPress download management tool?

    I’m wondering if this plugin would be compatible with the “PDF Viewer for WordPress” plugin

    If it isn’t compatible – do you know of any PDF viewers/managers that *would* be compatible with this plugin?

    Thanks

      PDF Stamper is an add-on for WordPress Download Manager Pro. We have a PDF viewer add-on too https://www.wpdownloadmanager.com/download/wordpress-pdf-viewer/ which works with PDF Stamper.

    Hello,
    in your demo (https://www.wpdownloadmanager.com/wordpress-download-manager-pro-demo/) I can’t find any option to enable pdf protections or encryption.
    I downloaded the file from https://demo.wpdownloadmanager.com/addons/download/pdf-stamping/ and I was able to print and edit the file, so the file protection or encryption is not automatic.

    Can I have more informations about this?
    Thank you, best regards

    Questions >

    1) Can this plugin stamp if the file is delivered from Dropbox or Amazon?

    2) Can I use a 3d party product to restrict access to the page on which the download link appears?

    3) Are you using liquid templating for the PDF stamper?

    9 years
    1. Shahriar

      1) Sorry, stamping will not work with remote files, as files need to be stored in the same server to customize it.
      2) You won’t need to use 3rd part plugin, wpdm pro has roles based and other kinds of protections you need to apply
      3) No

    Hi Shaon – Recommendation – Consider adding this to the next update of the PDF plugin. It would be very useful to anyone who needs to watermark the document with a time/datestamp in the event they are not “purchasing” the PDF, but just downloading it and want it to be marked with the download date.

    $arr[‘{today}’] = ”;
    $arr[‘{today}’] = $blogtime = current_time( ‘mysql’ );
    —————————————————
    {today} – The date of the PDF download- free

    Thanks
