My HP Color LaserJet 8550 is printing very distinct streaks. It seems to be in areas that have a lot of magenta. Any idea how to get rid of the streaks??

If the streaks are limited to a single colour, the problem is likely to be THAT colour TONER CARTRIDGE.

A problem with the DRUM UNIT (only a single drum in this printer) or the TRASNSFER DRUM , or BELT (this printer has both a transfer drum and a belt), would affect ALL colours.

There was bits of paper, from a stuck edge from a sheet of business cards that I think are perhaps still in the printer. When I print a colour sheet the alignment is off, printing black and white seems OK.

What do you mean by alignment?
If you mean that the colours are misaligned, run a full calibration. Repeat it three times and then try your printing.
If bits of the business cards were left in the printer - it should affect the colour printing as well as B + W. You would also be getting paper jams.

Xerox DocuColor 4CP printer will not print colour. It will print black fine though. Have defaulted printer and printed colour page, still no colour, just black.

According to this site, Windows 7 drivers are available for the Xerox Docucolor 4CP printer.
What operating system are you using?
Also, is it possible that your color toner has been depleted?

54.11(K), 54.12(C), 54.13(M), or 54.14(Y) Toner sensor error
Check the connections. Check the cartridge and replace it if necessary.
Replace the color registration detection assembly.
54.19 Transfer Belt error
Check the ETB connection. Replace the ETB. Replace the DC controller.

It is most likely that you have a faulty Toner Cartridge.

Color print does not line up blue is printed off center of red but black is fine.

Make sure you have the latest Firmware installed on your printer, this can be found at HP.COM/SUPPORT/CLJ2605. It sounds as though the problem you are experiencing is Colour Pane Registration problems. If you have the latest Firmware, then tryturning on Registration (Configure Device>Print Quality>Optimize) and perform 3 calibrations in a row. If the calibrations take more than a few minutes each, check the error log (Diagnostics>Print error log) for any CPR errors. You may need a replacement Laser unit.
