Application-specific print settings

Question

I use my iMac in my retail business for Point of Sale. I run credit cards through a browser-based processor, and I use Safari for that. I also use the iMac for everything else you need to do running a business, and so I've got three printers hooked up: a receipt printer, a label printer for price tags, and a laser printer.
Right now I have to change the paper size every time I print a credit card receipt from Safari (30-50 times per 8-hour day). It's not an option to set the label printer AND its paper size in the global print defaults (that is, when I set the default printer in System Preferences, it doesn't give me the paper size option, 72mm x 180mm. I only get that option in the application print dialog.)
My other problem is that having the default printer set as the label printer (since it gets used most consistently through the day) is that anytime I want to print anything else, I've got to change printers. And that's not infrequent, because I print 10-20 class schedules per day on the laser printer.
Is there any way to specify a print default that is application-specific? That is, anytime I click "print" in Safari, I get the label printer automatically, but anytime I click "print" in Preview, I get the Laser printer automatically? I'm flummoxed.
I've been looking at writing a script in AppleScript, is that the way to go? I tried making a workflow in Automator this morning, but it was slow and cumbersome, and no different than doing the clicking myself.
Any ideas? Thanks for your time.

Hi Ewa,
You could change owner firstly as below steps:
1. Open the registry editor to the following key - HKEY_CLASSES_ROOT\AppID\{316CDED5-E4AE-4B15-9113-7055D84DCC97}.
2. Change the permissions on the key itself by right-clicking on the {316CDED5-E4AE-4B15-9113-7055D84DCC97} key, and selecting "permissions".
3. This will open up a permissions dialog box. Click the "Advanced" button.
4. The key is owned by trustedinstaller. This needs to change before we continue, so click the "Change" link.
5. Assuming the account you're using is part of the Administrators group, just type in "Administrators" in the box and click the "OK" button.
6. Click the "Apply" button, then click the "OK" buttons until the permissions dialog window closes.
7. You will need to right-click the registry key again (from step 2) and select "Permissions" again from the list.
8. With "Administrators" highlighted, click to place a check into the "Full Control"/"Allow" box.
9. Click the "Apply" button, then click "OK" again until the permissions dialog window closes.
After done, run dcomcnfg as Administrator, you would see as below, continue the steps in the previous reply we discussed.
