Steps to reproduce:
1. Open / Create an writer-document which has many f-letters.
2. Print (tried at 2 identical Lexmark C782dn laser printers) with Postscript-driver.
Kerning right from / at f-letters is wrong (some interferre, some produce missing letters (Of ce instead of Office)
Normal Kerning and no missing letters. Works when using PDF-driver.
Operating System: openSUSE
Version: 188.8.131.52 release
The standard print job format on linux is PDF and this printer prefers PDF jobs over postscript according to this PPD which I guess you are using: http://www.openprinting.org/ppd-o-matic.php?driver=Postscript&printer=Lexmark-C782dn&show=1
You should verify that the CUPS isn't actually converting the postscript output from libreoffice to PDF before it sends it to the printer. This conversion process could be the source the kerning problems and missing letters.
I think my bug does match this: https://bugs.freedesktop.org/show_bug.cgi?id=67802
Thanks for your reply. Printing with PDF driver does output lower quality, so that's no solution for us.
Can I do anything (configure, send more information, ...) to help resolving this bug?

I can suggest you possible workarounds but cannot help you further:
Select a PDF backend to a printer, go to options and check Print to file.
Then print and open the PDF with a PDF reader. If the PDF is not blurry you can convert it to postscript before printing.
Another possibility is to remove
*cupsFilter: "application/vnd.cups-pdf 0 foomatic-rip"
from the printer driver (PPD) you use and only leave in
*cupsFilter: "application/vnd.cups-postscript 100 foomatic-rip"
Then configure the printer in libreoffice as PDF printer and use it. If this is done, printing subsystem (CUPS) will convert the PDF output to postscript before sending it to the printer.
