If your labels are marked as having permanent adhesiive, I think you might have a chance with them.
If you are using regular inkjet ink, I have found that you should print only in black ink and give the ink plenty of time to dry.
It all depends on the finish on the front of the label, the wonderful lady at Ripped Sheets, explained to me that on their label stock there is a special coating made of 'sand', which evidently locks the REGULAR INKJET ink onto the surface of the label. The have a less expensive stock than what we plan on testing, but it does not have as much of that coating on it.
Also, you might remember, that I'm using Epson DuraBrite Ink, and Malcolm has it too, I believe. Although you will have to find an Epson printer that takes that ink, I don't think they are out of line on their pricing, and same with the DuraBrite ink.
When we get to Session 11, we will find out. I would suggest you do the best you can for now, with what you have.
Good luck on your label printing.
