Third Party Driver Issues/question Follow

Alright - here's the situation. This is not a Seagull/BarTender issue at all, but it's presenting itself as a challenge.

We have a print press for our labels, and normally design print layouts for it in BarTender. They have provided a third party driver that works well, and we use that driver on all client PCs that are designing, so they can maintain a DPI consistent with the press while designing.

Here's the issue - our new PCs are not compatible with this driver, so I was trying to find a way to spoof the DPI of the press so that people could continue to design. However, BarTender gives me really weird and inconsistent mil size options for this press that I thought was 400 DPI. My mil size options are:

3.75 mil
6.25 mil
8.75 mil

So, BarTender is properly saying that the increment between each size should be 2.5 mil, but the minimum is 3.75 mil. :\ Any ideas why, or how I can replicate this on another PC without this particular driver. This is going to be a design hurdle for any users with the new Win7 64.

Edit: Then when I use another printer driver that lists 3.75 and 6.25 as options, and I apply those, the barcode sizes change by a little bit. So it can't be a true match.

Have you tried modifying the settings for the currently installed printer drivers via the "Administer>Advanced printer and driver setup" menu item? Maybe tweaking this will get you the results you need with the replacement driver you are using.

Thanks - I didn't know that was there. I knew you would have some sort of settings I could play with.

I'm confused as to why this driver shows a dpi of 400x400, but a dot size of 3.8. The math just doesn't work out on that... yet I don't see evidence of rough-edged codes when we actually go to print them.

edit: when I change from Inkjet to Thermal, it seems to have an affect on the dot size. I guess this is because ink can run a bit, and it looks like this press' drivers were set up with that in mind. But it's not an inkjet press. Lol. Well, I guess I understand where the inconsistency is coming from now - just to find the best workaround. Thanks for pointing me to that.

[b]Edit2: I see I can "Add Printer" on this screen, but it doesn't show up as a selectable printer during design. I must be missing something, as adding a printer to this list must have some effect, right?[/b]

The resolution and dot size of the printer as listed here is as the printer driver reports to BarTender. If it is wrong then it is the printer driver in use that is at fault. Yes depending on the type of print technology the dot size can be affected by ink spread which complicates the whole thing. Refer to the BarTender Help system for an explanation of this.

Concerning the "Add printer" option in the "Advanced printer and driver set-up" dialog I refer you to the below excerpt from the BarTender Help system:

"On the left side of the dialog is a list of printers, including all printers currently installed on your computer. Additionally, you can manually add printers to the list that are not currently installed. This may be useful when creating a printer settings file to be shared among multiple computers on a network."
