Created a simle app in Ionic v3 using below makepdf config on button click:

var dd = { content: 'This is an sample PDF printed with pdfMake' };
    pdfmake.createPdf(dd).download(); 

Throws error while testing on MAC for Fonts: 'Roboto-Regular.ttf' not found in virtual file system as this ttf is windows font.

makepdf version:
v0.1.28

Is file vfs_fonts.js with roboto font included after pdfmake.js?
i.e.:

  <script src='build/pdfmake.min.js'></script>
  <script src='build/vfs_fonts.js'></script>

I did not specify to use 'Roboto-Regular.ttf' anywhere in my app.

TTF fonts works on all platforms.
Roboto-Regular.ttf is default font of pdfmake library. This font is in default vfs_fonts.js file.
If you want own font see: https://github.com/bpampuch/pdfmake/wiki/Custom-Fonts---client-side

It does not work because:

• file vfs_fonts.js is incorrectly included

_or_

• file vfs_fonts.js contains a different font than Roboto and don't defined own font in docDefinition. See: https://github.com/bpampuch/pdfmake/wiki/Custom-Fonts---client-side
  Example:

  defaultStyle: {
    font: 'yourFontName'
  }
