The HP ENVY Photo 7155 has a passable design. The printer feels sturdy and well-built overall. Raising the scanner bed gives you access to the ink cartridges, even when the printer is off, and it also gives you access to remove any paper jams.
There are a few issues with the design. The main input tray isn’t removable, so it can be hard to load paper as space is pretty tight. Also, while the tray has width sliders, it doesn’t have length sliders, which can end up causing interruptions during print jobs. There’s a separate tray for photo paper located on top of the main input tray. The scanner lid doesn’t have any extendable hinges for thicker documents, and when lifting the scanner lid from the side, there’s a good chance that the scanner bed will come with it.
