Thanks Wendy & Denise for the suggestions. I have also researched Epson's SureColor series which seems to be comparable to the Canon's listed. A large format printer with 8 inks is definitely overkill for addressing postcards. The ability to print line drawings directly onto illustration board would be a nice feature, but not a necessity for me. This is one of those situations where incompatibilities are requiring workarounds with my particular set-up, otherwise I would just print onto labels. Time to upgrade everything and move to the cloud? I resist.
