A few weeks ago 60 Minutes ran a story about Khan Academy, a non-profit web site started by Sal Khan, who initially created online video lessons to help tutor his niece in math. Before long, others were following his video guides on YouTube and now the web site he helped start is one of the major online learning hubs on the internet.
As software developers, one of the issues we frequently encounter – especially in technical support – is how to explain things in simple terms so that even inexperienced computer users can understand our product and how to make it work.
Over the years we’ve expanded our online documentation and knowledgebase to include a lot of information on how to do different things and trouble-shoot problems, but now we are starting to add screen capture video to help explain the basic uses for Win2PDF. Here’s an example of a basic screen capture video that we used to describe how to create a simple PDF file.
For the video tutorial creation, we’ve played around with several different software packages and we’re currently using Camtasia Studio from TechSmith. So far it seems to work for our purposes.
The home for these new video tutorials will be our Win2PDF YouTube channel. Add it to your favorites in YouTube, or watch this space as we continue to add more tutorials.
The easiest way we’ve found — and one that can be quickly used with Win2PDF — is to send the PDF file as an email attachment directly to the Kindle device. The Amazon Kindle ebook reader supports PDF files through Amazon’s Kindle Personal Documents Service. In order to use this service, you must first tell Amazon to accept email from your email address. Use the following steps to enable email to your Kindle:
Under Approved Personal Document E-mail List, add your email address.
Under Send-to-Kindle E-Mail Settings, find and record your Kindle’s email address. This address should end in @kindle.com. This is the address that you will send PDF files to.
Once the Amazon Personal Document Settings have been configured, you can send PDF files directly to your Kindle by sending an email with the PDF file attached. Win2PDF users can send the e-mail automatically when saving a PDF file (see these instructions under “How to email a PDF file after creating it?”).
Please note that Amazon charges fees for sending files to your Kindle for some devices.
• For Kindle devices with Wi-Fi only (no 3G), there is no charge to receive PDF files. The Kindle must be connected to a Wi-Fi network to receive PDF files.
• Kindle devices with 3G, Amazon charges a small fee to deliver the PDF files over 3G if the Kindle is not currently connected to a Wi-Fi network. To avoid fees on 3G Kindles, you can use @free.kindle.com as the email address to prevent PDF files from being delivered over 3G.
Here’s another question we see quite frequently. Win2PDF has a feature to “Send file” that can be enabled on the file save window (see below).
When this option is checked, Win2PDF will create the PDF file and automatically attach it to a new email message using the computer’s default MAPI email client (which is typically Microsoft Outlook or Windows Live Mail).
But what do you do if you want to attach the PDF to a web-based e-mail client like Gmail or Outlook Web Access? Since these programs don’t install as a full-fledged email client, how can you use these programs with Win2PDF?
There may be other ways to do this, but we found a software program called Affixa that has a handy way of solving this issue. Many applications have the built-in capability to send emails, including Win2PDF, but most rely on an external email client. Affixa effectively resides in the background and acts as a connector to these web-based email services. When you use the “Send file” feature in Win2PDF, for example, it will automatically create a draft web email message with the PDF attached. Voilà!
Affixa is free for personal use and only about $3 per license for business use. And it works for any application that has a similar ‘Send to email’ capability, like Microsoft Word. And it can be configured to work with multiple accounts (like Gmail, Outlook Web Access, Yahoo mail, etc.)
[Note: we have no affiliation with Affixa – we just found their solution to be quite useful when used with our Win2PDF software].
Since we added PDF/A support in our most recent Win2PDF 7 release, we’ve had some questions about this new type of PDF file. First, the basics.
What is PDF/A?
It’s basically a subset of the PDF file format used to archive data for long-term storage (the A stands for PDF/Archive). It is an ISO standard (ISO 19005-1:2005) that does not need to depend on external programs or information to be displayed, all information is entirely self contained. It does not permit the inclusion of any executable scripts, audio, video and/or encryption. In contrast, a regular PDF file may substitute fonts (because not all fonts are saved in the original file), and may have these other types of data “linked” within the PDF file, but not “contained” within the PDF file.
Why is it increasingly being used in government (and courts in particular)?
It’s an ISO standard file format. Regardless of what application creates the PDF/A file, all PDF/A files will conform to the same rules. Which is good for…
Archiving. Since these files are self contained buckets of information, the file will be able to be viewed in the future and look exactly as it did when it was created. If the PDF file linked to external information, there is no guarantee that information would be accessible in the future.
It’s more secure and readily accessible. Again, since it doesn’t allow encryption it keeps the document accessible, and since it doesn’t allow external links to data sources, it prevents security exploits. And finally…
It’s mandated in many situations. The Administrative Office of the US Courts identified the potential risk of not being able to reliably access archived digital files in the future in 2010. Since then, many district Courts now mandate the PDF/A standard for court documents. It is also mandated by law in several European countries.
With Win2PDF 7, just select “PDF for Archiving (PDF/A)” as the Win2PDF file save type. [Update: Win2PDF will create a file that complies with the PDF/A-1b standard)]. It will still have a .pdf file extension, and it is just as easy to create a PDF/A file as it is to create a normal PDF file.
How do I know Win2PDF has created a PDF/A file?
First, make sure you have the latest version of Adobe Reader installed. Then, open the PDF file and you’ll see a notice in Adobe Reader that states: “The file you have opened complies with the PDF/A standard and has been opened read-only to prevent modification.”
We frequently get questions about our product (Win2PDF) and its support of digital signatures. While we have investigated adding this as a feature, there are many variations in implementation and some general misunderstandings of what “digital signatures” really are that makes it difficult to provide a universal solution to this problem.
Generally, when people speak of ‘signing a document’ they mean to apply some form of electronic signature to the PDF, and this can be done either simply (typically called an electronic signature), or in a way that is more advanced (typically called a digital signature). A brief explanation of both:
An electronic signature is a general method of signing an electronic document, and it typically works by associating a marker (such as a .JPG representation of a person’s hand-written signature) to a PDF file. An electronic signature is easy to implement, but also offers fewer protections and can be easier to forge.
A digital signature is a more sophisticated implementation of electronic signatures that associates an encrypted “fingerprint” on a PDF file. This “fingerprint” is unique to both the document and the signer and ensures the authenticity of the signer. If the PDF is changed after it is signed, it invalidates the signature. Generally, it is a more secure method of protecting the integrity of a signed PDF file.
There are several different approaches to signing PDF files, and different organizations may require different levels of sophistication in their files. A legal document sent by a lawyer, for example, may have a more stringent requirement for authentication than, say, a document that just needs an ‘sign-off’ by a manager for a particular internal process.
So, which version will you need? That will require some more investigation on the type of solution that best fits your business needs. One interesting recent development is that the latest version of Adobe Reader has announced some native support for “electronic signatures”. While this isn’t an advanced digital signature solution it may suffice for many users. And because the basic signing capability is included with Adobe Reader the implementation is easy.
Adobe acquired Echosign (a company specializing in signature technology) in July of 2011, and earlier this month they announced that the native Echosign functionality was included in the latest Adobe Reader application. This integration will allow users to electronically sign any document in Adobe Reader (with a new “Sign” button) and then send the document out for others to sign through the Echosign web site. Here’s a screen shot of the new Adobe Reader interface.
There are some free capabilities for a single user, but to effectively use this electronic signature capability within an organization requires a subscription to Echosign.
This is an interesting development for many users, but it still may not be the right solution for all companies. Other companies offering digital signature solutions include Identrust, Appligent, Arx, and DocuSign.
Back to the discussion of incorporating the digital signature feature into Win2PDF? Well, because of the variety of solutions available, and the different requirements for different organizations, we’ve found it best to provide a method to integrate with other solutions instead of trying to create a solution that will fit every user’s needs. We do this by providing a mechanism to a launch an external application after creating the PDF file with Win2PDF.
Actually, if you are interested in this Win2PDF mechanism, send an e-mail to [email protected] and ask for more details. We have a Win2PDF Admin Utility that can make this a little easier, but we don’t have it fully documented… yet.
