C# printing in dos mode

Question

Dear all

Its been some time, i have been trying to print bills in dos mode using C# , i was unsuccessful so i have given my client printing in normal mode using crystal reports. I am using VS 2005 & SQL 2000. But i would like to give a try again printing bills in dos mode.

I am using continueous paper with 6 Inches height and 5 inches width on wep 800 dx printer. i would like to align text in the following way. i would like to know how to eject paper after printing each bill so that it wont print next bill in the balance of the first page.

I have used the below code provided by J O'Donnell, this code is pretty good its printing very fast but its printing only junk characters & printer gets stuck in between. I have sorted a little we must use only monotype fonts to make printing fast + we have to make printer mode to Generic / Text only. I would like to get guidance on how to send the printing values directly to printer and how to align it properly, so that when you look at the print out it must look nice.
