W98 Workstation Loses All Printers

I have always thought this was a NetWare client issue, but now think it is win98 issue. I have a user with the latest NW client 3.4 on a NW6SP3 network who has her printers go off line frequently and sometimes they all disappear, rebooting remedies temporarily. I did a google and found 29,000+ hits, but no good answers. The interesting thing was that most of them were about losing printers on a Windows network with Win98 so that is why I don’t think it is a Netware client issue. Plan to eliminate win98 completely this year, but in the meantime???
