After installing Adobe Acrobat patch 9.4.2 printing breaks for some network printers (e.g., HP 3015 or HP 2055)
- Go to (C:\Program Files\Adobe\Acrobat 9.0\Acrobat)
- Find “Adobe.Acrobat.Dependencies.manifest”
- Open it with notepad and delete line “22”
- Reboot your computer
This should fix the issue of being unable to print PDF file after installing 9.4.2 update for Adobe Acrobat.
