Your choice is between Ink Tank and Laser.
If you are going to take prints at least once ever week, you should go for an all in on Ink Tank. It will give you the facility of color prints and scans, whenever necessary. You can go for the Wi-fi ones, they are very convenient for printing/scanning directly from mobile phones.
You can go for the Laser printers, if you will be taking prints with long intervals, and need faster prints, and are sure you wont need color or scans.
Print costs should be similar for both.
