2.7.1 PrintingIf anything, computer systems have made it easier to produce paper documents. It isso easy to run off many copies of a letter (or book), in order to get it looking ‘justright’. Older printers had a fixed set of characters available on a printhead. These varied from the traditional line printer to golf-ball and daisy-wheel printers. To change a typeface or the size of type meant changing the printhead, and was an awkward,and frequently messy, job, but for many years the daisy-wheel printer was the onlymeans of producing high-quality output at an affordable price. However, the drop inthe price of laser printers coupled with the availability of other cheap high-qualityprinters means that daisy-wheels are fast becoming a rarity.
