HP Laserjet M600, M601 Issues with printing from Browser

Question:
we have two print Laserjet M602 and M601 that have often a « 49.4a.04  Error ».
Peoples who often use it, print almost just on their browser.

After reading the release note of the firmware 2302908_435019, it’s write :

« You may see a error 49.4A.04 Error when printing PDF and Web file »it’s not really clear for me, because it’s inside the « fixes » case but this sound like

« you may see it more often….. »

Before made this Firmware Update i need to know.

If this problem is solve in the new Higher version of this Firmware (2302963_436082) ?

Where can i Download my actual Firmware for roll it back ?

Solution:
These issues have been resolved and are available in the New firmware release. Please update the Firmware on printer and that should resolve the issue.
