Every time I print it gives me an error message Error:0xc0620004411:lib_micci2.c I've tried unplugging it and I've reinstalled the printer to my computer.

Remove the cartridges and do a full reset without them in by removing the wall socket and re-plugging.

More information has been answered in another thread.

Unplug overnight. No help? remove print cartridges and reinstall.
Try your printer "troubleshooting" panel on your computer for more help.

Hi, 

open the rear access door and clean the rollers with a cloth, dam it with little water and unplug the machine and press and hold the ON button for 1 min and release the button and plug in the power cord, it should resolve the issue.

reinstall your driver and also check usb connection cable.

What is the exact error message and what is the make and model of your printer please?
In the meantime, you would probably want to try a hard reset and a reinstallation of the driver.

Hard reset:
Unplug printer from mains and PC
Wait for 15-20mins
Hold power button on and replug printer to mains and PC.

Try this first and also send me the error message and make model of your printer.

Thanks

My printing stops and I get this error message Error-0x07a74dd6 1959:lib_barracu.
What is the meaning to this and how can I fix the problem?

reset to factory defaults, also check the whole printer for paper jams. A paper jam can often casue smaller pieces to get stuck in gears or rollers. The message about opening and closing the lid is how the printer knows you went in to check it and closeing it triggers it to try again. If thers still a jam it will keep giving the message. The fist jam was caused by something, check and make sure there isnt any pieces of plastic broken off inside. If it has a rear access panel, check there also.
