Hi,

Please specify your AutoCAD version.

If it is AutoCAD 2016 for Mac:

>>>> lines are missing
Possible cases:
- the lines are on non printable layer. Solutions: make layer printable via Layers palette or move lines to the printable layer
- the lines have zero lineweight and you are viewing PDF file in Preview application. Solutions: use Adobe Acrobat Reader application to view PDF files or change lineweight of the lines to something greater than zero.

>>> words and letters are misplaced
Possible cases:
- you are using specific True Type font (or Open Type Font) for the Text Style. Solutions: try to set system variable USEQUARTZFONT=0:

or try to use different TTF (OTF) font for the Text Style.

>>>> etc.
Can you be more specific?

You can also attach your problem drawing along with PDF output for further investigation.
