ran be achieved with software, which mav agreatly simplify Blotting applications. The various software selectable options are invoked by sending an ESCape code followed bv specific byteta) to the printer. Underlining can be turned on or off at will. The printer can be instructed to set the left margin of the print area, and alsa the riqht margin, forcing the type ta weap around when this position is exceeded.

These can all be accessed by using the appropriate ESC code, followed by bytes indicating the length of the ogranhic code following, then by the bytes of qraphic information. As the graphics are potentially very powerful. a cursory demonstration of them would not do them justice, sa [ won’t attemot one. I am looking forward toa linking the Fsebe@ to my still to be delivered Climax Colour Graphics board to draw (via Suitable sattware! 3 Gichkures in black and white of the screen contents.

The level shifting circuit is dealt with in detail by David in S@BUS News Vol i, No %, om. 34,

As Io am sure ia obvious, [ am very pleased with the printer. Tt costs anoroax £4 pius VAT. and the Gk serial butter costs approx £1LSS. A rall paper halder is stranaly Sormmericleecl , and tractor feed would be necessary for label oar narrow form handling. Its speed of 164 cps is very impressive. though it does slow down for twiddly bits. I Suqqest that many of ibs users will opt to drive it at 9604 or 19.2bk baud. I look forward to many years of service fram it, when I have finished customisina my text editor to allow for the differing spacings and type densities. This is being written on a quickly cabbled up set of patches to an existing text editor, but the printer demands better than that!
