My laptop prints everything in A5. Although I have set A4 really everywhere. If you print to this printer from another laptop, it does it right. So it must somehow be down to my Pdfs or something… What else can I try? I'm freaking out
Troubleshooting must always be systematic.
First of all, always print a normal Word letter in A4 if this normal comes out.
The Windows test page, which is always printed on A4 format, is also helpful.
Are you using the original Adobe PDF Reader (latest version)? Compatible is not always 100% compatible.
otherwise have a look here. (Windows 10)
