Chapter 12. IBM 3713 Printer
USES
In many applications data originated at a remote site is pro-
cessed at a centralized computer location, and reports or
other documents that are based upon the processed data
are used at the remote site. If time is not important and
the source documents can be spared at the remote site, they
may be mailed to the central site, keypunched, processed,
and reports printed and mailed back to the originating site.
HARDWARE
The IBM 3713 Printer (Figure 32) is available as a feature
attachment on the 3741. It enables the 3741 to prepare
hard copy from disk offline. The matrix printer has a
maximum rate of 40 characters per second and a maximum
line length of 128 characters. Three different pin feed
platens, with pin-to-pin widths of 12-1/2,13-1/8, or 13-7/8
inches are available. Forms with a maximum thickness of

However, if time is important, the 3741 Model 2 with
attached 3713 printer may be used to key the data at the
remote site and transmit it to the central computer for pro-
cessing over night. After processing, output reports are
created and transmitted back to the remote site for storage
on diskette and for offline printing.
The following examples illustrate some of the advantages of
using a printer in this type of application.
Improved Customer Service:
Retail chain store orders may
be keyed on 3741's at a regional warehouse, transmitted
periodically to the central office computer for a run against
consolidated inventory files, and picking slips transmitted to
the appropriate shipping warehouse for offline printing on
the 3713.
Reduced UFloat" of Funds in the Mail: In the example
above, invoices can be transmitted to the warehouse for
printing and mailing when the goods are shipped, resulting
in prompt billing and reduced cash "float."
Better Business Control:
Labor cost data may be keyed on
a 3741 at a construction site, transmitted to a central com-
puter for analysis and cost distribution, and management
reports sent back to the site for printing there. The timely
receipt of cost analysis by site management permits correc-
tive management action before cost overruns occur.

feeding and stacking, IBM recommends using no more than
three parts.
Adjustable Margins Feature
An adjustable margins feature permits the use of nine addi-
tional platen widths ranging from 7-1/2 to 11-1/2 inches
pin-to-pin. By manually repositioning margin stops and
interchanging platens, the customer can use the variety of
printer forms his applications require.
Forms Stand Feature
This feature permits placing continuous forms on a stand
above floor level, and provides for stacking them after print-
ing.
FUNCTIONS
Printer Modes
The 3713 can print in four different modes (each with or
without printer format control):
• Print record--the current buffer data is printed.
• Print data set--the current data set is printed.
• Print under search contento-the records found within the
current data set under search on content are printed.
• Print under search address--the record found under
search on address is printed.
