Printer Formatting
The format of output on the printer can be controlled in
one of two ways:
1.
2.
Local format control--the location having the printer
can write printer format programs and load these pro-
grams into the program level buffers of the 3741.
CPU format control--the transmitting station (usually
a central computer) can send printer control charac-
ters intermixed with data. The printer control char-
acters determine the format of the output.
The choice of format control method depends on the user's
requi rements . Local format control would probably be
selected if :
• Control and flexibility of print formatting is desired at
local site.
• CPU output reprogramming can be avoided.
CPU format control would probably be selected if :
• Maximum teleprocessing efficiency is important (accom-
plished by eliminating unprinted blanks, zeros, etc. and
by packing data into large transmission blocks) .
• Maximum data storage on disk (s) is desired.
• Central control of printer formatting is desired .
