When printing my papers, I noticed something odd: while the letters of documents exported from Word were clean around the edges, PDF compiled by LaTeX usually had some kind of grainy imperfections in letter cursive. This perplexes me, as there shouldn't be any difference between the two documents — they are both PDF. Are there any options that can be added to the source code to fix this problem or at least enhance the quality of the prints? Thank you for your answers in advance.

EDIT

Due to request, here's a MWE:

\documentclass{article}

\usepackage[T1]{fontenc}    
\usepackage[utf8]{inputenc}     
\usepackage[slovene,english]{babel}

\begin{document}

Slovenian: Zakaj so moje črke zmazane? \\

English (translation): Why are my letters blurry?

\end{document}

As you can see, I use T1, so OT1 encoding can't be an issue. I don't know if slovene babel font is scalable though.

Here you go, (perhaps) the log file.

    People will be able to help you better if you include a sample document that illustrates the issue (and perhaps even a PDF). The most likely cause is that the PDF is using a bitmap font at a resolution lower than (not translating well to) that of the printer. But without an example, it's just guesswork. – ShreevatsaR Feb 16 '18 at 19:47

    A couple of your previous questions (1, 2) indicate you have some sub-optimal fonts setup in your TeX installation; what you observe here may be related to that. – ShreevatsaR Feb 16 '18 at 19:52

    you are most likely using bitmap fonts. Almost all fonts usable from TeX are available in scalable format these days so there might be something wrong with your setup or you might be using a font that is only available as metafont generated bitmaps. impossible to say given no information in the question. – David Carlisle Feb 16 '18 at 20:16

    Check the end of the log-file. If fonts with the extension .pk are reported you should install the cm-super package. – Ulrike Fischer Feb 16 '18 at 20:57
