>I have a form with a control treeview and a couple of buttons, one of them is an impression button, this button calls to another form, once I selects the nodes that I want to print and I oppress the impression button, the first time it usually prints, if I want to print again, when pressing the button the computer hung up and I should turn off it.
>I followed it with debugger and it is hung up in the moment in that the impression button calls to the other form, I proved the same form in another computer and works normally.

In all probability, it's a known problem with the printer driver (HP-supplied drivers are the most frequent culprits.) If you have not applied Visual Studio SP3 and replaced the VFP runtime on all stations, that may fix the problem (which resulted from the print driver leaving the FPU in an unstable state.)

If that doesn't fix it, you may have to revert to using an older printer driver from a compatible printer; for example, the HP 4 laser driver is a solid and well tested driver that can be used instead of the drivers for most of the more recent HP printers. You need to use the driver from an MS operating system distribution to test the proble.
