Bar printers were alike to chain printers however were slower and less pricey. Slightly than a chain moving incessantly in one way, the lettering was on finger mounted on a bar that motivated left-to-right and next right-to-left in face of the paper. An illustration was the IBM 1443.
In all the design, timing of the hammer was grave, and was flexible as part of the service of the printer. For drum printers, wrong timing of the hammer results in printed lines that wander upright, albeit with lettering correctly align horizontally in their column. For train as well as bar printers, wrong timing of the hammers resulted in lettering changing horizontally, although on vertically-level printed lines.
Mainly drum, chain, and bar printers were able of printing up to 132 columns, but a few design could only print 80 columns and some other design as many as 160 column.
