The HP ENVY Photo 7155 is a decent family printer for printing photos. It has good color accuracy and photos look vibrant, but it takes quite a bit of time to print them and the single color cartridge runs out pretty quickly, so it can be very expensive if you print a lot. It doesn't perform all that well when it comes to black only and color documents, as the printing speed is also very slow and neither cartridge yields a lot of pages. The scanner lacks an Automatic Document Feeder, which can be problematic for offices that need to process long double-sided documents. On the bright side, it has great connectivity options and there are high-yield cartridges available if you often print in large numbers.
The ENVY Photo 7155 is a decent family printer. Printed photos look vibrant and color accuracy is good, but they have a warm color temperature, resulting in a slightly reddish tint. It does take quite a bit of time to print photos, though, and it has bad yield for both color and black pages, so the cartridges need to be replaced often. The scanner only has a flatbed and it can't extend for thick books or documents.
The ENVY Photo 7155 is a bad printer for home or small offices. It performs rather poorly for printing black or color documents, as it has a slow printing speed and low page yield, so the ink needs to be replaced regularly. The scanner doesn't have an Automatic Document Feeder and it can't perform duplex scanning, making it difficult and time-consuming to scan long double-sided documents.
The ENVY Photo 7155 is an okay printer for students. As this printer is mainly intended for printing photos, it doesn't perform all that well when it comes to black only documents. Not only does it take a lot of time to print, but the cartridges also have poor yield, so you have to replace them often and it can get quite expensive over time. Also, scanning features are limited, as it lacks an Automatic Document Feeder and can't perform duplex scanning.
The ENVY Photo 7155 is a poor printer for printing black and white documents. It takes a long time to print and due to the low black page yield, the ink cartridges need to be replaced often, which ends up costing a lot more over time. Luckily, the printer accepts high yield cartridges and third-party cartridges.
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.
The ENVY 7155 is a compact printer that's very similar to the HP ENVY Photo 7855, except that it's shorter due to the lack of an Automatic Document Feeder.
The 7155's display console is sub-par. Although the menu is easy to navigate, the display itself isn't that great. The viewing angles are poor and it can't tilt or swivel for better visibility. Pressing on one of the icons on the top bar only brings down another menu, so you have to press the appropriate icon a second time to access the actual settings menu. Also, accessing the settings menu can feel laggy and unresponsive at times. If you are looking for a printer with a better display screen, check out the HP ENVY Photo 6255. Both printers are very similar but the 6255 has an easier to navigate display screen.
The ENVY Photo 7155 has a bad cartridge system. It doesn't have any photo ink cartridges despite being a printer that's intended for printing photos, and it only has one color cartridge. Both black and color page yields are low, so the cartridges need to be replaced quite often. Furthermore, the printer continues to print blank pages even when it's completely out of ink. On the bright side, there are high yield cartridges available and you can also subscribe to HP's Instant Ink service. The printer accepts third party cartridges, although using them may void the warranty.
The 7155 has mediocre scanning features. The scanning resolution and color depth are fairly standard, but as it only has a flatbed, scanning multiple pages or two-sided documents can be rather tedious and time-consuming.
The ENVY 7155's cost-per-print is okay. Even though the cartridges are reasonably priced, you still end up having to replace them often due to their low yield, costing more over time. This applies to both black only and color printing.
Keep in mind that even if you print only in black, most inkjet printers continue using the color cartridge for servicing tasks, so you'll likely still need to replace it eventually.
The ENVY 7155's printing speed is passable. It takes a long time to print pretty much everything, whether it's black only documents, color documents, or photos. Thankfully, the input tray can hold up to 125 sheets of paper, so you can leave it running for a while before having to reload. The output tray, however, can only hold up to 25 sheets.
The ENVY 7155 has good color accuracy, although there are still some inaccuracies with most colors, with dark greens and dark blues being the worse. This should be fine if you're printing casually, but may not be good enough for professionals who need accurate color reproduction.
The ENVY 7155 has very decent photo printing quality. The color temperature seems to be on the warm side as there's a slight reddish tone to all the images. Yellows appear vibrant and the colors are well-defined, but there's some banding in the grayscale.
These results are based on the actual physical photo, not the scanned image provided for reference above, which may not be representative of the printer's photo print quality.
The ENVY 7155 supports most common paper sizes up to the standard legal size. The main input tray has sliders to accommodate different width, but not for length, which can lead to interruptions during print jobs, as the printer may be unable to grab the sheets of paper. Also, the input tray is only long enough for letter-size paper and there's no extension, so legal-size paper ends up hanging off the edge of the input tray.
The ENVY 7155 has great connectivity options. The printer has an SD card reader; it's located on the front left side of the printer and there's a round cover protecting the port, as you can see in this photo. It's rather unfortunate that it doesn't have an ethernet port, and while there's mention of Bluetooth support, it can only be used to set up the printer, not to perform any print jobs.
The HP Smart mobile app is decent. It lets you print photos and documents directly from the app, and you can also quickly scan documents using your smartphone's camera, albeit at a maximum resolution of 300dpi. Additionally, you can send mobile faxes from the app and manage your ink subscription if you're subscribed to HP's ink delivery service.
Although it isn't advertised as a variant, the HP ENVY Photo 7855 bears a lot of resemblance to the ENVY Photo 7155. The main difference is that the 7855 performs a bit better, it has more connectivity options, and the scanner has an Automatic Document Feeder.
The HP ENVY Photo 7155 and the HP ENVY Photo 6255 are two very similar color printers. Both printers don't perform all that well when it comes to black only documents. Their printing speeds are very slow, and neither cartridges yield a lot of pages. However, the 7155 has a slightly better color accuracy and photo printing quality. The biggest plus for the 7155, is that it supports external storage like an SD card or USB thumb drive.
The HP ENVY Photo and the HP LaserJet M15w are two very different printers. If you are looking to print in color with a focus on photos, then the Envy is a better option. If, however, you want to print in black and white, with a low cost-per-print and a high black page yield, then the LaserJet is your best bet.
