What is optimal min & max heap size, should give while running qz-tray.

In ubuntu machine, I did not face any issue, but once i tried in Windows 8.1, getting out of memory.

PS- was printing HTML page.

Thanks

HTML printing in QZ Tray 2.0 requires more memory.  We have modified our launching method to launch the software with 512MB of memory.  This should be able to handle any HTML printing.

Can you please tell us how you are launching the software? For example: shortcut on desktop, auto start, etc.  This has been thoroughly tested but we may have missed something when implementing this.

What is optimal min & max heap size, should give while running qz-tray.

If you are running the software via command line:

 

java -Xms512M -jar "%PROGRAMFILES%\QZ Tray\qz-tray.jar" 

 

Regards,

Kyle
