Please note that Aspose.Words requires TrueType fonts when rendering document to fixed-page formats (JPEG, PNG, PDF or XPS). You need to install fonts e.g. ‘Helvetica LT Std’ that are used in your document on the machine where you are converting documents to PDF. Please refer to the following articles:

How Aspose.Words Uses True Type Fonts
How to Receive Notification of Missing Fonts and Font Substitution during Rendering

You mean the server that convert the doc to pdf need the font right?Anything we can do to programmatically fix this?Installing font is only option?Can we know the list of possible fonts aspose is expecting?

You need to install font ‘Helvetica LT Std’ on the system where you are converting document to PDF.

The required fonts for rendering are those which are used in your document. E.g. in your shared document only ‘Helvetica LT Std’ font is present. Below code example shows how to gather the details of what fonts are present in a document.

Document doc = new Document(MyDir + "Document.doc");

FontInfoCollection fonts = doc.FontInfos;
int fontIndex = 1;

// The fonts info extracted from this document does not necessarily mean that the fonts themselves are
// used in the document. If a font is present but not used then most likely they were referenced at some time
// and then removed from the Document.
foreach (FontInfo info in fonts)
{
    // Print out some important details about the font.
    Console.WriteLine("Font #{0}", fontIndex);
    Console.WriteLine("Name: {0}", info.Name);
    Console.WriteLine("IsTrueType: {0}", info.IsTrueType);
    fontIndex++;
}

In this case we know its ‘Helvetica LT Std’, but we dont know what are the possible fonts docs are comimg.Do you have recommended font list?

The recommended fonts for document rendering are those that are used in the document. You can use the code example shared in my previous post to get the list of fonts used in the document. You can also get the missing font notification using the code example shared in the following article.

we cant handle the missing font on run time.We were just trying to get all common fonts that need to installed on server.Do you have a list of common fonts recommended was the questions so we can install it on the server as base

The common fonts are available on Windows operating system. You can find them in Windows/Fonts folder. Please check the list of common typefaces from here:
