Go here for a description of this new update:
http://support.apple.com/kb/HT1893 If you have HP drivers/printers you should see the following in the Apple Software Update list: HP Printer Driver Update v1.1.1
This particular version -- 1.1.1--installs the following:
HP Designjet Z3100ps 44in Photo - PCL3 raster 2.3.1
HP Designjet Z3100ps 44in Photo - PS 4.3.5.153
As far as I can tell these are newer versions of these drivers than you can get from the HP website. I did a fresh install of the newest on the HP web site this june and the following versions were installed:
postscript: 4.3.3.109
raster: 2.3
The Apple "Software Update" mechanism installed newer versions of both. I have no clue what new features are in either new version--the ps or the raster. They seem to work.
It might be the case that HP only distributes driver updates through the Apple Update mechanism. (I know that Snow leopard will come with new HP drivers:
http://support.apple.com/kb/HT3669#HP the Snow Leopard Versions are:
HP Designjet Z3100ps 44in Photo - PCL3 raster 3.3
HP Designjet Z3100ps 44in Photo - PS 5.3.0 )
current problem:
If anyone else is taking this route for installing Z3100 drivers, I do have a question. My software update went off for "HP Printer Driver Update v1.1.1" AGAIN this morning. Since it is the same update that i previously installed, I am quite reluctant to install it. I down loaded the package without installing it and looked inside it using Pacifist (package extractor for Mac OS X) and was able to see that the PPD files in this package were the same as the ones installed in my system. I might have been looking at the wrong files though.)
Has anyone gotten a similar Update for the same "HP Printer Driver Update v1.1.1"? Have you installed it? Have the version on your print drivers changed?
And do let me know if I am entirely confused here...
