I have been using HP printers for many years now. They are affordable, compact and have reasonable printing cost.
Recently I purchased HP 3776 multi-function printer. I would like to point out some main features which may pursuade or dissuade you from buying this particular model.
On positive side, it is compact, affordable and provides good wi-fi interface. Printing is very easy using android app. Cartridges are also available easily. All functions - printing, scanning and photocopy are available.
But there is a big drawback. This printer is not able to scan or photocopy small-size documents. It works only with A4 size docs. So, if you have to scan or photocopy PAN Card, Aadhar card, Driving licence etc; you will not be able to do it successfully.
Please do keep the above points in mind when you consider buying it.
