I'm using a PC with Windows XP Professional and an HP PSC 500 printer. The printer connects through a standard parallel port, but for some reason, whenever you print it disconnects the USB cable modem, which is a Toshiba PCX 2200. It use to do this with no explanation and was solved by powering down the modem and then starting it up again. More recently it gives a message in the Notifcation Area that the USB ports have experienced a Power Surge and tells me to disconnect them and then press a "Reset" button at the bottom of the notifcation window. This reconnects the modem, but what's going on here, and how can I keep it from happening every time I print?
