Hi, just started using Linux (Ubuntu) 2 weeks ago. Installed my Canon bubblejet and that works fine.
Downloaded the SLP Linux driver from SIIbusinessProducts.com for the SLP450 label printer and followed the install instructions for CUPS and associated libraries with no errors.
Printer starts and prints one line of solid black before halting.
Tried the "lp" command as well.
Spent days and days on this. Even re-installed Ubuntu.
My kids have put me on suicide watch.
