Why do I have 6 installed printers when the correct number is 0?

My SD Card slot is corrupted.

I was under the impression BRCM was Broadcom Wireless hardware?

LaCie XtremKey is a USB flash drive.

What do they have to do with printers. Something queer is going on with this printer business. I don't own a printer. I haven't needed to print a page in years. But TM crashes prior to completing a backup. The logs don't say much but they talk about the xxx/cups folders being fiddled with (as the reason for the failure of Time Machine to...function).
