The BA-45 Micro Business Manager was one of the nice applications of the miniaturized printing technologies introduced with the TI-5000. The calculating capabilities of this 4-bit microcontroller (uPD7500 series) are less than a BA-II. A similar product was launched with the TI-45 Micro Scientific Printer.
If you need more powerful financial functions and like a alphanumeric prompting you should go for the Canon Financial Printer.
The only serious desktop printing calculator developed for financial applications was introduced already in 1983 with the rare TI-5310.
The paper used with this printer (PMF05228 1-1/2" wide and 14 Feet length) is still available at different sources, e.g. shoplet.com.
