Problem installing HP network printers in an HP Thin Client T5500

[EMESES]

Hi All

I have a print server that contains 5 printers (HP LaserJet 4000 Series, HP LaserJet 4200 PCL 6, hp LaserJet 1150 PCL, HP Color LaserJet 4600 PCL 6 and Epson LQ 2080) installed and shared, all my network users (who use desktops) work with these printers without any problem except for an HP T5500 User (thin client) that shows only 1 printer (Epson LQ 2080) but not the 4 others which I need the most.

PS: When I do : start=>Run=> and I type "\\theprintservername", I see only the Epson printer and not the others.

Should I activate something in the 4 printers or in the thin client or is driver issue?

Any help is too much appreciated.
Thanks in advance.
