I did experience slow PDF (invoice) generation with my prestashop upgrade to 1.6.5 and found the fix. Maybe worth to try for your image PNG logo issue.

 

 

 

Upgrade the 3rd party software tcpdf which is located in tools/tcpdf

 

 

 

First make a backup of tools/tcpdf

 

Download the zip from https://sourceforge.net/projects/tcpdf/files/

 

unpack it and copy it OVER the original one

 

 

 

If you replace the whole folder then prestashop still cannot generate invoices. Maybe there is a file in tools/tcpdf which is prestashop specific. I didn't look into this as it's working now.

 

 

 

My tcpdf upgraded from 5.9.179 to 6.2.11. The version is listed at the top of the tcpdf.php file

Hi, I'm experiencing slow PDF generation too. I've tried updating tcpdf, and also I've make sure the logos are in JPG.

Still generates them too slow.

I also have a test prestashop different store as a test environment, and with same configuration (also PHP configuration), it works great.

Does anybody have any clue about this problem?

Much thanks.
