Hidden printer in NT 4.0???

I have an HP Laserjet 5p connected to a JetAdmin network box shared as, “Sales_Laserjet_5p”. Everyone prints, etc. no real problems, except that when I browse the network to add people to this printer it is not visible!? I made sure that there is no “?” in the name to make it a hidden share and I checked all the printers options, but there are none to hide it from Network Neighborhood. I can connect to the printer if I type the name manually in the ports box. Any ideas of why it’s hidden?
