I have a couple of Dymo LabelWriters. One is a Twin Turbo. The other is a single 330. I have been using these and, earlier, other Dymo printers for many, many years, since the first models originally on Windows machines and more recently (8 years) on Mac hardware. I keep all of my machines up to date.
First item of interest: --> I have been using both printers successfully with 10.9.4. I don't know why it works for me but not others. "It just works."
But not any more!
Second Item: --> I upgraded the iMac to 10.9.5 and it insists the printer is not connected. I did a major housecleaning of all Dymo related material and reinstalled only to get the same result.
I connected the printer to a MacBook Pro running 10.9.5 and which never had an Dymo software installed. It responded the same way. Everything is OK until you actually try to print and the error message insists the printer is not connected.
1. OS X seems to think there is no problem, i.e., the printer is listed as an active USB device and as an installed printer at idle.
2. Every installation of the Dymo 8.5.1 SW proceeded VERY slowly toward the end of the installation, while running scripts, just before it says to connect the printer. It ended "successfully", and a check of the printers in System Preferences shows the Dymo printer as installed and idle. When I try to print a label, the ONLY thing out of whack is that the popup printing box says the printer is not connected.
The Mac Pro running 10.9.4 has a
Comment: It's one thing to say, "10.9.5 is a new version and we haven't caught up yet," although there has been plenty of time and information available to be on time for the release, but it's another thing to abandon a product like this which, frankly, ain't all that complicated. Last, the communication channels regarding tech support seem totally muddled with no centralization and therefore multiple answers, some or all of which seem erroneous. These printers have been great when they worked, albeit expensive for the materials. But the real expense has been the time necessary to make them work at all, particularly in the update/upgrade cycle.
