Some users have recently had their accounts hijacked. It seems that the now defunct EVGA forums might have compromised your password there and seems many are using the same PW here. We would suggest you UPDATE YOUR PASSWORD and TURN ON 2FA for your account here to further secure it. None of the compromised accounts had 2FA turned on.
Once you have enabled 2FA, your account will be updated soon to show a badge, letting other members know that you use 2FA to protect your account. This should be beneficial for everyone that uses FSFT.
They make converter cables, but they are a generally bad idea. Most require drivers since the cable actually has to convert from a serial to parallel format. I don't know where you can find a cheap parallel, as most printers that have parallel these days are the nicer ones, which maintain bacward compatibility by having both ports.
