Win’98 Lotus Notes printing problem

We run a small network on Windows NT, with the PC’s running Windows 98. On the network we have a Domino server hosting Lotus Notes release 4.6.7, each PC has it’s own printer; Laserjet 1100. When creating a document in Lotus Notes, on some machines, the printed document looks different from what is on the screen: one long line of text on the screen will wrap round on the print and use up two lines which can result in a one page document being printed on two pages. As far as I know, settings are the same, but I don’t know where to start tracing the problem: is it a Windows problem? is it a Lotus Notes problem? or a printer configuration problem? Your guidance much appreciated.
