Very difficult - try a vacuum cleaner first. However I suspect the carpet will be ruined - do you have household insurance - you may be able to get a replacement carpet.
A laser printer uses a dry toner powder in a sealed cartridge.
Laser printer ink toner in laser printers is a powder and can last for years depending on the amount of use. This time will vary based on the manufacture of the toner and the printer.
A mixture of rubbing alcohol and water or a commercial carpet stain remover can help to remove ballpoint ink from carpet. Blot the stain with the solution and a clean cloth, working from the outside in to prevent spreading the ink. Repeat until the ink is no longer transferring to the cloth.

No; inkjet printers use a water-based liquid ink. The ink is held in a (usually) replaceable cartridge. Ink is propelled in extremely fine drops from openings on a print head (either on the cartridge or within the printer) onto a printable medium, generally paper. Laser printers use powdered toner.
An ink jet printer refers to a printer in which the characters are formed by the minute jets of ink.
Toner is inside of some printer cartridges, while ink is in other printer cartridges. Typically, a toner filled cartridge will cost more than an ink cartridge. However, an ink cartridge has to be changed a lot more.
There may be multiple problems with the printer (or the ink cartridges): Does the printer have empty ink cartridges? If so, put in fresh ones. Did you refill the ink cartridges? Use remanufactured ones? If so, then they may be: overfilled, heads/contacts worn out, ink level detector not reset (on some ink cartridges), etc. Is anything (that's part of the printer or ink cartridges) broken? If so, it may be too broke to work. Are the ink cartridges expired/dry? If they are expired, some printers say they don't detect them, thus they won't print. If they are dry, then they won't print. Try doing a head cleaning. Either with the printer's software, the printer's head cleaner button, or with cotton swabs and rubbing alcohol. Did you touch the ink cartridges (where the printer's/ink cartridges instructions) said not to? If so, clean them. Are the contacts on the ink cartridges/carriages dirty? If so, clean them. Is the paper loaded/inserted? If not, load/insert the paper. Are you using the wrong size/weight/amount of the paper? If so, please use the correct size/weight/amount of the paper. Is the printer communicating with the computer? If not, plug 1 side of the USB Cable into the printer, then plug the other side into the computer. Is the printer on? If not, turn it on. If this doesn't work, plug it in. Then turn it on. Does the printer have a paper jam? If so, clear the jam. Does the printer have objects in it? If so, get the objects out. Is the printer dirty (on the inside)? If so, clean it.
Yes, black printer ink is cheaper than colored ink in general. It's also easier to refill black ink yourself.

Makeup is one of the hardest things to get out of carpet. One of the best things to remove cover up is peroxide, but you'll need to make sure that the dye in the carpet can withstand it. Most carpet cleaners, like Resolve, will eventually remove the stain.
Printer cartridges are what holds the ink. You insert these into the specific place in the printer, and the printer uses the ink from inside the cartridges.
