Locoscript supported 150 characters and, if used with the dot matrix printer, could print European letters including Greek and Cyrillic, as well as mathematical and technical symbols. The program allowed the user to work on one document while printing another, so that the relative slowness of the basic printer seldom caused difficulties. Locoscript did not run under the control of a standard operating system but booted directly from a floppy disk. Users had to reboot if they wanted to switch between Locoscript and a CP/M application, unless they used a utility called "Flipper", which could allocate separate areas of RAM to Locoscript and CP/M.
