HELP for Dummies

I've got a Toshiba Satellite, A215-S4747, & I got a hand-me-down printer, a Hewlet Packard printer,scanner,copier (aka "HP PSC 750) & I'm wondering what kind of cable to get to hook them up to each other. Normally, this would be a moot point but I had a stroke eleven months ago & this all new to me again.
The other thing is that I got this computer as a 'floor demo' model & it came to me missing the letter ''F" button. I was told I could get a whole 'nother keyboard & just swap it out but I tried that & just wound with one that had keyboard issues. We tried to swap the key but they had a different way of locking themselves down & wouldn't work.
What's a stroke survivor like me to do?? Any help is of some help. Thanx

 

A USB "A" to "B" cable, very common cable.

As for the keyboard, you need to buy a keyboard for that specific model. You can also use a USB keyboard and just ignore the laptop's keyboard if you're not carrying it around.

 

Just wanted to say "Thank You" especially you got the answer off right away & you sound right on the money. Thanx,again. B. Ray Mick
