I have a number of all-in-ones of various makes, all are or have been very good workhorses.Some people may advice that all-in-ones are problematic, but I have never really found this to be a true case.
HP have been very good, in fact I am still using an ex-retired HP 960 OfficeJet on occasions. The inks are still available for this very old model.
But over recent months, HP have been a little lacking with support, to the sadness that a previously very good Photosmart C3180 as been destined to the store cupboard. A simple problem that HP have given up on!.
If its print ink consumption you want, then consider a printer that will accommodate a CISS (Continuous Ink Supply System) or cheap easily available compatibles.
Canon, Lexmark and Epson all have their own little oddities, whether that is a print head or ink problem due to lack of use, or noise and slow speeds etc.
At the moment I have been using on a daily basis a Brother DCP-135C. Great product with cheap compatible cartridge availability and CISS if required. Its literally printed off thousands of various formats from stiff card to photo. I also obtained an extra 2 year free warranty extension on registering the product. This particular product cost (I believe) £39.99 from Rymans about 12 months ago.
I would point out that virtually all my printers have been in the price range of £9.99 (Dell/Lexmark) delivered to less than £56.00 except the old HP 960 when printers were expensive.
I don't know if Staples still have a returns policy on unsuitable products like printers. It might pay to find this out!.
Hope the above helps!.
