Some of the companies that manufacture travel printers Canon, Hewlett-Packard, SiPix and Pentax. Canon portable printers include the PIXMA iP110 wireless mobile printer and the BJC-80 portable printer. HP's travel printers include the OfficeJet H470 and the Deskjet 460c. SiPix has one of the smallest travel printers, the Pocket Printer A6. Pentax offers the PocketJet 3 Plus mobile printer, another extremely small option.
The Canon PIXMA iP110 is one of the most popular and well-rated small travel printers. The printer is 12.7-by-7.3-by-2.5-inches and weighs 4.3 pounds. It is compatible with cloud printing and printing from mobile devices such as iPhones. However, some reviewers on Amazon.com have noted that it is difficult to setup.
The SiPix Pocket Printer A6 is billed as being barely larger than a wallet. However, it has received mixed reviews from consumers. Positive comments include that it is robust and very compact. Negative reviews indicate that its customer support and compatibility with modern computers are poor.
The Pentax PocketJet 3 Plus Mobile Printer, another extremely compact option, is only 2.2-by-10-by-1.2-inches and 4.2 pounds. One review indicates that it fits perfectly into a computer bag. However, another reviewer indicates that this printer may not work well with Macintosh OSX.
