I need HP Printer Driver for Vista - DriverHeaven.net
gave hint to use hp deskjet 5400 driver instead of the hp business inkjet 2230 driver i have been trying for days with my Netgear PS101 print server (v1?). Finally works, at least for a complete looking test page and the preferences for the 5400 printer seem clearer than those given for the 2230. maybe that is why print servers and printers are not working...it is the driver supplied by HP is wacko for vista?
