Type bars are vertical bars, one for each print position in a line. Each bar is one character wide with the printer's entire character set: either alphabetic characters, including numerals and symbols, or just numerals and symbols, molded into the front surface in a single column. In printing, each

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.

bar is raised up until the correct character for that print position was opposite the paper, whereupon the bar is pushed toward the paper, so that the correct numeral or letter pressed against the ribbon, striking the paper much the way type slugs leave an impression on paper in a standard

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.
