Laserjet 3030 and Officejet 7210 both 'All in One'

Question

Both printers purchased and being used in U.S. with 110V. Am thinking about taking them with me when I move to South Africa where voltage is 220. I believe Laserjet 3030 will work with a transformer and adapter on 220V, correct? And is it possible that Officejet 7210 has dual voltage built-in (looking at product specifications, but am not sure) and therefore I will only need an adapter? Thank you for all feedback.

Hi @MacBimmer ,
I see that you are experiencing issues adding the printer over the wireless network back onto Yosemite. I will certainly do my best to help you.
Power cycle the router and restart the Mac and printer.
Follow these steps to Verify and Repair the Disk Permissions.
On the Apple menu bar, click Go, then click Utilities.
From the sub menu on the right, double-click Disk Utility .
From the list on the left, select your drive or active partition.
Click the First Aid tab, then click Verify then Repair Disk Permissions.
Restart your computer.
Reset The Printing System:
Note: This will delete all the printers listed and you will have to add them back in again.
Go to the Apple, System Preferences, Printers and Scanners, hold down the control button on the keyboard and click your mouse in the white area on the left side of the window, select Reset Printing System when it comes up and put in the Mac password. Then click the + sign, select the printer,  then click on the add button. (you might have to click on the dropdown to select the printer name from the list)
If you are having network issues, then add the printer through the IP Protocal.
After clicking the + button, select the IP across the top, type in the printer's IPv4 address, select jet direct below and then Apply.
Test the printer.
If you need further assistance, just let me know.
Have a nice day!
Thank You.
