>>>Has anyone seen cases where VFP crashes to the point of getting the blue screen of death when trying to select a printer in VFP? This only seems to happen when the user has one of the new cheap laser printers installed on an old PC. I now have one customer using an HP 1000 and another with a Brother. Both are conneced to "old" PCs and both crash when my printer rnt is called. I'm not sure yet what command it is crashing on but it most likely is aprinters().

You might consider upgrading to SP 5, though it may not help. The problem is probably with the driver as Cathy noted, so upgrading them if possible may help. The older drivers may not be written in accordance with the DDK and may be the cause.
