>>> Details
>>>
>>> Validating file "Dokumentum-2.pdf" for conformance level pdf1.3
>>> The glyph for character 96 in font 'AxeHandel' is missing.
>>> The glyph for character 221 in font 'AxeHandel' is missing.
>>> The document does not conform to the requested standard.
>>> The document contains fonts without embedded font programs or

>>> The document does not conform to the PDF 1.3 standard.
>>> Done.

>> I send to a professional printer, and I usually outline all fonts.

>> As a side note, I do not recall you mentioning which version of
