I am relatively new to Linux-Ubunyu 16.04 system runung on an oldish DELL Dimension 3100 desk top PC. The printer I try to install is Canon PIXMA MP510 printer that is about 3 years old and was used on a Windows (ugly word) system BUT I don't know how to install it.
Can anybody please help. Would appreciate if the knowledgeable helper (not a self appointed user) could give advice on <email removed>
Many thanks in anticipation for your help.

You need to read the LQ Rules, and the "How to ask a smart question" and "Question Guidelines" links in my posting signature. First, this is a community forum..if you want help, then you participate in the conversations/threads here. This isn't the place to come for free, personalized one-on-one email tech support. And telling people you'll only accept help from certain folks and not 'self appointed user' (whatever that means) is just plain rude. If people are volunteering (as we all are here) to help you, telling them what you'll accept from that help isn't good.

Since you only want help from "the knowledgeable user", putting "canon mp510 ubuntu 16.04" into Google yields this as the very first hit:

...a written, step-by-step guide with pictures. Additionally, you can run
..to install the drivers, and configure your printer as normal after that.

Please do not persist with posting an email address as an option for members to get back to you. This has been stated to you before.

To the OP, as a general rule, since everything you put online is permanent, you should try to remain anonymous to the general population using google. At the very least your inbox will be filled with spam. At worst, you'll leave a trail of information online to allow others to discover your true personal identity.

After that, everyone knows everything you've ever put online and can pin it on you, forever, and there's nothing you can ever do to undo it. You might say, "I have nothing to hide." Then I say, "Dance around naked on the streets of New York City."

That's what it's like to use real info online!

Many thanks for your helpful info.
Also I withdraw my statement on knowledgeable helper. My apologies.
Regrettably I am not good enough to use your excellent forum after all I am 85 and when I need some help I try all avenues.
Again, many thanks for your help.

Age has nothing to do with this; seems odd that you're quite 'good enough' to have full specs on your systems, exact model numbers, and have been able to load Linux perfectly well (and use it), but when it comes to doing research you're too old?? Doesn't add up.

The links posted are complete instructions with pictures...cannot get easier than that. Follow the steps one by one, or even just type in that one command I gave you. And again, research yields lots. Putting "how to configure a printer on ubuntu 16.04" gives you, as the very first hit:
https://help.ubuntu.com/stable/ubunt...ing-setup.html

...step by step instructions. Type in that one command to install drivers; follow above guide to configure printer.
