NCR RealPOS 7197 Printer Migration Guide
3
•
Blocks all new 7197 commands. This means it will prevent
execution of any commands that did not exist in the 7193/94
printers.
•
Executes all commands supported on the 7194 as a 7194, though the
same command may operate differently in 7197 Native Mode
•
Automatically scales user-defined bitmap graphics for the 7197,
such as store logos to print in the same size and location, as it
would have on the 7193. Without 7193 emulation, the original
image would be printed dot-for-dot the same on the 7197, resulting
in a proportionally smaller (~25%) image that is skewed to one
side. With 7193 emulation, an algorithm "scales" up the image by
adding dots to the bitmap in order to re-create the image in the
same proportions with higher resolution. Note that because the
algorithm is essentially guessing where to put the dots to expand
the image vertically and horizontally, the image may appear
slightly different. Differences may be noticeable on smaller images
or on details in larger images.
What 7193 Emulation Mode does not do:
•
Does not slow down printing. Improved performance is a function
of a faster thermal print mechanism, how the application and
driver sends data to the printer, and baud rate. Putting the 7197 in
7193 Emulation Mode does not "gear down" the speed of the
mechanism. See separate note on performance below
•
Does not scale a user-defined downloaded character. The 7193,
7194, and 7197 support downloaded characters, typically replacing
an unused character or symbol with a special letter or symbol used
in the customer’s application. The 7193 character is composed of
fewer dots vertically and horizontally (6 dots per millimeter versus
the 7194’s and 7197’s 8 dots per millimeter). The 7193 Emulation
Mode does nothing to increase the number of dots used in the
character, consequently the character created for the 7193 will
appear smaller on the 7197. Examples from actual customers
include a backwards "R" for Toys "R" Us, and a down arrow symbol
used by another customer to flag marked down items on the
receipt.
