you'll have at least a dozen different answers!

I have never used a portable printer. Blog about your selection.

I use an app on my phone ScannerPro. Cost $2.99 from app store. Best money I ever spent. Open the app, take a photo and it creates a pdf document. Then I can email or text directly from app. Love it!!

I bought a HP office jet 200 Portable printer with free shipping. I love it. Easy to set up, easy to use and everything i need. 

I have been happy with all of the cheap 3in1's at Walmart, HP, Canon, and others.

All work about the same and are very cheap, except for the expensive ink.

I'm sure you'll get some good answers, Olga... but not from me... I have a big honker of a Lexmark in my office and don't print portably. Had one years and years and years ago... and it never really worked well and was a pain to carry around.

Ken Jones, ASA, CRES gave you a great suggestion!

Good luck, Olga Simoncelli! 

How talented are you with a chisel on slate Olga Simoncelli ?

You have many answers here Olga Simoncelli 

I think that Ken has the good buy suggestion.

I use a free app... Evernote Scannable for iPhone, been happy with this when out and about.

I have been using  a Brother 2700...

Sorry, it's been a long time since I've looked into the portable office in the back of the SUV.

Olga Simoncelli Here's a comparison chart and information that PC magazine did on portable printers for 2018:

I've got nothing.  My chimney guy uses a portable printer. Beyond that, I've got no experience with them.

I have always had good luck with HP products.

I am so glad you asked this question Olga Simoncelli as I too would like to find a good small portable printer for myself. Preferably one that fits right in my laptop case.

I've never used a portable printer so I can't help. Others have provided some ideas for you. Good luck.

Olga,

You have several answers here.  A

Never used one. My Epson Workforce 2650 is still doing all I need. Good luck!

I bought a portable printer YEARS ago, and never used it.    Looks like you got some suggestions.

Olga Simoncelli - never used one - so checking other suggestions.

Portable? Do you mean you want to transport it everywhere you go? I use a scanning app and don't need copies. 

They are all made of plastic and most likely made in the very same factory.

Based on how PORTABLE your needs are, such as Ken's baggage and flight requirements. the greatest concern you must have, and have no way to get the answer, is how does the printer manage the ''waste" ink created from borderless printing and cleaning ink jets.  If waste ink ends up in a reservoir, inversion of the printer will be incredibly problematic. If waste inks ends in a sponge or other absorbent material. you are good to go.  Of course the same issue exists with eco-tank printers. 

I would buy what ever Staples or Best Buy is promoting at the front door and get the warranty if you know this printer is headed into an inclement environment.

Barbara Todaro nailed this one!

Thanks Ken
