No one is answering elsewhere, and traffic seems decent here, so...

I have an older printer (no USB ports) so got a converter cable to connect
it to my laptop..no problem; software loaded, printer registers as default,
and it worked fine a couple of times but now...NO. I click print (document,
email, web page, anything) and it comes up on the screen as going to
printer, but the printer doesn't turn on, and my system shows "six jobs
waiting to be printed." How the heck do I get them OUT of the buffer!????
