Look at the Brother HC4120 or HC 4170, think they would do the job. Font size would be something you would set in the software from which you are going to pring, WORD/WORKS etc. I mentioned the two Brother printers because they are relatively inexpensive to purchase and to use. The main differences between the two is that the 4170 has network capability, wireless and hardwwire, should you require one or both of those features.
