NCR RealPOS 7197 Printer Migration Guide
If poorer than expected performance is seen, and if increasing the baud
rate has been tried, or is not an option, the customer is encouraged to
modify the application to send the entire receipt down at the end of the
transaction. With information now stored in buffered memory, the
printer no longer has to wait on the application or communication
interface for instructions on printing the next line. If the application
does buffer the transaction in this manner, it should also be modified to
be able to recover the complete transaction if necessary due to a
printing problem.
Note on Cash Drawer Operation
The 7197 provides a single cash drawer port, which is the same as the
7194. The printer will support a dual drawer configuration, with a Y-
cable. With the use of the Y-cable, the printer can sense that a drawer is
open, but it cannot report which drawer is open. It is left to the
application or device driver to keep track of which drawer was opened.
As indicated at the beginning of this document, these and other
differences are documented in the NCR RealPOS 7197 Owner's Guide,
