HP Printing: we have several networked HP printers - all inoperative on MACOS X

From today these have stopped printing, because the Code Signature is Invalid. Apple needs to take urgent action. We have restored some functionality by using a default PS driver, but this will not work for all.

How did anyone think this was acceptable.

Anybody got a good way around this? There is an article here which explains the problem a little more. We found using IPP did not help.
