I need to know what kinds of printers are being used with Radio Shack
models 3 and 4. Am preparing a program which makes extensive use of printer
features such as 80 columns, underline, 132 columns, etc.
Would appreciate specific info on these printers as such:
  
 CHR codes which start and stop underlining,

 CHR codes which initiate 132 column mode, and start 80 column mode.

Please either leave responses or mail...Thanks!!
(I am guessing the most popular non RS printers are Epson, gemini, and heath, 
for example, but I need as much info as I can get!! )
