Re: Dymo 320 USB - no writeable port?

I've been playing around with a Dymo label printer, model 320, which is a
USB printer.  My system recognizes it fine and attaches the usblp driver,
but the appropriate port (/dev/usb/lp1) is unwriteable. Yes, I'm sure it's
lp1 because lp0 is the regular laser printer on this machine.

Here's the syslog trace from when the printer is plugged in:

...But here's what happens:

Any advice? Thanks. Andy
I can't give you any advice about getting the right port to work, but I can relate my experiences with the same and a couple of other Dymo label printers, we have them attached to some mac's, they will only print properly with the software that Dymo supply. We use them for printing chemical labels, which can be quite complex, I had the smart idea of making up the label in Quark, did it and then selected the Dymo driver and it was impossible to select the correct label... also when you use their software in edit mode the cursor is 5 or 6 characters away from where in reality it is, you get used to it, but it is a PITA, I have been in contact with their tech support, but to no real avail, pity really as it is a great little printer, but the software is crap. And the rolls of labels are really expensive too. I wish you every success in getting it working, post back if you get anywhere with it.
