I don't know how to print lables from Ecel 7

Adjust vertical offset in printer properties. If that doesn't fix it, adjust it under "advanced". Or... you can set the offset in the printer itself. Hold down the left two buttons at the same time. Cycle through the settings until you get to vertical offset.

Printing labels is a pain! It is much easier to print using an A4 sheet with (say) 7 rows of 4 labels on.
I suggest you use the Ricoh support site

To find your WiFi password, locate your Wireless Access Point (Might be built into the Modem) and look on the underside if it. There will be a lable saying "WiFi name", "Passphrase" etc. That Passphrase is the WiFi password.

I don't know what Make, Model printer you have but look at the website of the printer manufacturer.

You can control the format of your print-out via your Windows Printer properties (e.g. in W7: Control Panel -> Hardware and Sound -> Devices and Printers -> Printers and Faxes section -> Double click on Printer -> Pinting preferences) : under Preference/Features - 'Color Options' should set to 'Print in Grayscale'.

If the cartridges you're using give you poor results, throw them away cos you don't know what other damage they might be doing.

I'm not saying don't use budget cartridges, just bin them if they don't work properly and get a different brand.

Alternatively, are cheap cartridges worth all this hassle?

You need an updated driver that works with Windows 7. Go to the following link, click "Software & Drivers", then select "Windows 7" from the drop down menu. You will want to install the first item on the list for networked printing, or the second item if you don't need networked printing.

Make sure your supply voltage is the same as what it is rated for.
