Hi. I am using a Linksys PSUS4 (http://www.linksysbycisco.com/APAC/en/support/PSUS4) print server with a HP Deskjet 950C. I had no problems printing from a Windows OS. I swtiched to a Macbook Pro 15" (MAC OS 10.5.8) recently, ensured that I could detect my print server using AppleTalk and installed the latest drivers from Apple and HP. Whenever I tried to print from my MacBook, the printer prints rubbish. I am unable to adjust any printing settings, like to print colour or grayscale, ink usage and etc. Please advise how I can solve this problem. Thanks much!
