019- Where can I get Imagewriter II ribbons?
Several common printers use this same ribbon: the NEC 8023, some Citoh,
etc.. Office Depot sells the black ribbons-- Nu-kote brand, part# NK160-- for
about $5 each. They also carry the Color ribbon. Sams Club may still sell them;
or, you can order the ribbons through Staples and Hallmark stores.
Another source is [e-mail]. In a newsgroup posting he offers
to supply black ribbons for about $.75 each plus shipping ($3.55 for up to
around 10) and color ribbons for about $3.00 plus shipping.
