Reciept printers are standard text based printers, they do not require any special driver. You can use the standard text based printer driver from windows if you want.

All you do is send text to the LPT port it is connected to, Haven't played with VB and this though but an example off the good old days would be like

dir > lpt1

and all the text that gets displayed is sent to the LPT1 port which the printer can handle fine. Reciept Printers are measured in Col size so most times it is a 80 column or 23 column so on and that is the max chars allowed across the width. Hope this helped a little.
