1443 printing capabilities

The IBM 1443 Printer was introduced as part of the IBM 1440 system. The 1443 Model 1 prints alphanumeric, upper-case only, output at a basic rate of 150 lines per minute, and it can print up to 430 lines a minute with a restricted character set, depending upon the type bars used. The Model 2's and Model N1's corresponding speeds are 240 and 600 LPM. The typebars are easily interchangeable, with options for character sets containing 13, 39, 52, or 63 characters. The print speeds vary according to the model and the character set. The 1443 printer uses 120 or 144 print hammers and hammer magnets, conceptually similar to the IBM 1132 printer's one-per-column print magnets. Output is formatted at 10 characters per inch, with a choice of six or eight lines per inch, with additional options for single, double or triple-spacing. The 1443 uses fan-folded paper with perforated edges for tractor feeding. A carriage control tape specifies form length and the form line where printing was to begin so that paper of various sizes could be used. A carriage control tape simplifies use of pre-printed forms and the programming needed to allow proper alignment.


Successor technology

Type bars were replaced by type wheels or a drum in later printers, most notably: * IBM 407 - introduced 1949 - type wheels - adapted as an input/output unit on the

* IBM 1132 - introduced in 1965 with the low cost IBM 1130 computer system. The 1132 was the last printer manufactured by IBM to use the 407's technology. In 1959 this technology was superseded with the introduction of the IBM 1403 chain printer; both the 1132 and 1403 were available with the 1130.
