I bought a HP 19C printing calculator and it came with some rolls of Radio Shack thermal paper that are 1 7/16 inches wide (3.7cm). However, they appear to be too narrow, as the paper is a very sloppy fit and wobbles side to side as it advances. It appears that the correct width is approximately 1 1/2" inches wide. Does anyone know what the correct size is and the HP part number? Assuming the HP product is no longer available, is there an alternate brand equivalent.
Thanks,
Michael
