Hi,
Thanks for your feedback.
After testing your case with Spire.PDF Pack(Hot Fix) Version:6.1.8, I didn't find the issue with multi line text box. The font in it would be automatically reduced. Here is my test project:
http://www.e-iceblue.com/downloads/demo/20090.zipI used HP LaserJet P1007 and Adobe to print your file. Attached is the result printed by Adobe. If there is still the issue after running my project on your side, please provide following information for further investigation.
1. The OS and Region information, e.g. Win7 64bit, China/Chinese
2. The name of the printer you used
3. The printed result you got, you could provide a screenshot of it
4. Change a printer(e.g. Microsoft XPS Document Writer) or save to PDF directly to check if the issue still happens.
Sincerely,
Betsy
