How to enable High Quality Printing and disable other options in VeryPDF Advanced PDF Tools Command Line?

Hi Support,

I recently purchased VeryPDF Advanced PDF Tools Command Line and encounter an issue as below:

pdftools.exe -i C:\Users\Andrew\Desktop\test\abc.pdf -o C:\Users\Andrew\Desktop\zz.pdf -d "20230801131311+08'00'" -m "20230801131311+08'00'" -c "" -p "abc" -S ownerpwd=ABC -S keylen=2 -S permission=128

What I'm trying to achieve here is to change the Created & Modified Date, Creator, Producer, Permission password, Security level and with only Printing in High Resolution Permission enabled.

However all is working except the permission Printing in High Resolution and Document Assembly is not changing accordingly.

Kindly assist.

Thanks for your message, you may use [-S "securitykey=-1852"] options to instead of "-S permission=128" to try again, for example,

pdftools.exe -i D:\Downloads\202308311528030767.pdf -o D:\Downloads\_out.pdf -d "20230801131311+08'00'" -m "20230801131311+08'00'" -c "" -p "abc" -S ownerpwd=ABC -S keylen=2 -S "securitykey=-1852"

The new options of [-S "securitykey=-1852"] will able to protect your PDF file with High Quality Printing and disable other options.
