Trace Printing
You can automatically print a record of your calculations.
Trace Printing Off (rR~~, Flag 32 Clear). No automatic printing
occurs.
Trace Printing On (T:~.fI~:., Flag 32 Set). Each time the command
line is executed, the calculator prints the contents of the command
line, the operation that caused execution, and the result in level 1.
Auto CR Mode
Generally you want to send data to the printer and print the data
with a single command. In other cases, such as printing graphics, you
want to accumulate data in the printer without printing. This mode
determines whether print commands automatically cause printing.
Auto CR (Flag 33 Clear). Print commands send Carriage Right at
the end of transmission, causing the data to be printed.
Accumulate Print Data (Flag 33 Set). Print commands send data
without Carriage Right, causing the data to accumulate in the printer
buffer.
Print Speed
The calculator can't sense when the printer is ready for more data, so
it
computes the rate at which data can safely be transmitted. This
mode determines whether the computation is made for a printer
powered by batteries or one that is powered by an adaptor.
Normal Print Speed (Flag 52 Clear). The calculator sends data at a
rate suitable for
battery-powered printing.
Faster Print Speed (Flag 52 Set). The calculator sends data at a
rate suitable for adaptor-powered printing.
