Do you use HP UPD for all HP Laserjet for your organization? How did it work out using iprint and UPD? I rather not use UPD since it got so many issues in the past. It looks like I don't have any choice though. For example I can't find Color laserjet 5500 driver on Hp site (except for UDP). In Imanager broker upload page, built-in drivers for windows 7 does not list hp 5500. There is a function in windows 7 that allow you show more printers drivers if you chose "windows update" option. This will show hp 5500 driver in the list. However, I can't do that step with imanager driver upload page. Therefore I can't upload this hp 5500 to the broker. Any suggestion would be appreciated. Thank you.
