It depends on what hardware you want to install.
If its a USB device, like a key, stick it in, and type
you will get an output similar to this
Code:
usb 1-5: new high speed USB device using ehci_hcd and address 13
scsi7 : SCSI emulation for USB Mass Storage devices
usb-storage: device found at 13
usb-storage: waiting for device to settle before scanning
Vendor: Flash/SM Model: Super Talent 2.0 Rev: 2040
Type: Direct-Access ANSI SCSI revision: 00
SCSI device sdf: 506880 512-byte hdwr sectors (260 MB)

sda: assuming drive cache: write through
SCSI device sdf: 506880 512-byte hdwr sectors (260 MB)

/dev/scsi/host7/bus0/target0/lun0: p1
Attached scsi removable disk sda at scsi7, channel 0, id 0, lun 0
usb-storage: device scan complete
This indicates that it has been detected, and assigned to /dev/sda (in this case, /dev/sda1)
So all you have to do is mount it now
Code:
mount /dev/sda1 /mnt/hd
And there you go.
As for printers, most are compatible with CUPS. make sure you have CUPS installed, and running, and go to your internet browser to this link
http://localhost:631/
If you can't then cups may not be running
Code:
cd /etc/rc.d
chmod +x rc.cups
./rc.cups start
EDIT: If you want to check if you have cups installed or not, just type
pkgtool -> View, and search for it. If its not installed, then download and install it manually
