IR-90/91 and the ERC-18 cartridge ribbon.
We have noticed some people have a hard time finding receipt paper in some pretty common sizes. We offer 44mm bond (requires ribbon) as well as 44mm thermal receipt paper (no ribbon required). We also carry all the other normal sizes like 2.25" thermal and even 2 and 3 ply rolls.
Don't forget to protect your cash register with a keyboard cover. We carry all the covers for SAM4s cash registers and most if not all of the commercial grade Sharp cash registers.
If you are looking for cash register supplies give us a call at 1-800-863-2274 and we will try and help you out.
