[6] Many companies such as Watford Electronics provided utility-ROMS that allowed customers to use 'macro-commands' to call pre-programmed escape-sequences for their printers, vs. having to memorize / refer to cheat-sheets every time they wished to enable a font-change.
(The BBC computer did not natively support the display of these font effects on-screen) Expansion hardware (paged RAM) tools were also manufactured by companies such as Watford Electronics, to enable larger printer-buffers, and print-previewing of large documents in the 80-column screen modes.
This approach was later expanded on by Computer Concepts for their 1987 ROM SpellMaster, which paged 128k into the 16k address space and acted as a spelling checker for InterWord, Wordwise and View.
40- and 53-column views were also available if a larger font was required or to reduce screen memory footprint, and the display would scroll horizontally when narrower than the printed page.
InterWord could not use the extra-low-memory teletext mode except for its main menu, and recommended that the machine have Shadow RAM (like the BBC Master) so that screen memory would not be an issue.
