Can anyone help with a problem I'm having with my Color Stylewriter 2400?
Today, after I connected an external CD drive, upgraded from Clarisworks
3.0 to 5.0 and installed Internet Explorer 4, the printer happily printed
the IE4 licence agreement in Catalan (I wanted it for educational reasons!)
and most of the Spanish version before finishing off in stripes. Since
then, it makes all the right noises but either prints nothing or various
sorts of irregular stripes (not like the effect you get when you need a new
cartridge, though I have, of course, changed it to no effect). It won't
even print the test page, again producing either a complete blank or
various sqwiggles. Surely the ability to produce the test page shouldn't be
affected by my various installations (which seem to be working OK!)? Any
ideas?
