At first, it is fantastic. After 2-3 years and with minimal use, it stopped printing and gives an error for changing the print heads. Also, every time I want to print, it shows an error, and I end up doing my work after two hours of cursing. The worst printer I have ever bought.

I bought this model for 250 euros. After using it for a few days, I realize that the printer is amazing. It has a Greek menu on the screen, as well as instructions in Greek on the packaging. The prints are flawless, both black and white and color. I was especially impressed by the excellent color printing on plain A4 paper. The prints are relatively fast and the noise is low. I connected wirelessly to my computer running Windows 7 and everything works perfectly. Immediate response. Of course, it also has an Ethernet port, as well as a USB port. Also, printing from my mobile phone is very easy and fast. It comes with six inks, 3 black 170 ml each and 3 color. Essentially, the 2 additional black inks are for future use. Assuming that what the manufacturer says about 6000 black prints for each ink is true, with the purchase of the printer we have a margin for approximately 18,000 black and white prints and also for 7,700 color pages. And since the cost of inks is very cheap, the printer's cost is easily recovered. Finally, it has all the other basic features, such as double-sided printing, photocopying, and scanning. It also has a special closed cassette-holder for up to 250 A4 sheets.

Update 17/05/2024. From 5 stars to 1. Many problems after 2 years of purchase. Continuous printing jams and finally in the 3rd year it gave up. It displayed error 5B00 on the screen, which practically means that it cannot be repaired even by CANON. Stay away, you will regret your money.

Yesterday I received the Canon G6040 (purchased for €250). It will replace a Canon MG7150 due to the cost of ink cartridges.
The Canon G6040 was chosen based on having the same capabilities as the MG7150 but with cheaper ink cartridges.
I liked the following features of the MG7150 (which the G6040 also has):
1. Closed tray for A4 paper. (The experience with open rear trays has shown that you either have to insert paper before each print or keep the paper permanently, resulting in dust entering the mechanisms, eventually reaching the print heads).
2. Automatic duplex printing.
3. Scanning from the operation panel and sending to the selected computer (always from the printer's operation panel). This feature is useful when connected via Wi-Fi and the computer is not next to the printer.

In general, the G6040 performs as stated in its specifications.

The only negative aspect is its operation panel (monochrome with two lines and not illuminated), while the 5-year-old MG7150 had a color touchscreen and touch buttons.

What concerns me is whether the mechanism that lifts the operation panel from a vertical to a horizontal position will withstand the test of time.

I hope it lasts for 2.5 years, which is the amortization period based on the cost of ink cartridges for the MG7150.

15 days after the purchase.
The printer prints slowly (more than 5 minutes for the Windows test page). It took me an afternoon to figure it out after extensive searching on the Internet. It turned out that the drivers included in the installation package recommended by the instructions are faulty. I had to clean the installation from the computer, download a package from Canon that only contains drivers (newer than the recommended package), then install the initial package to add various additional programs. This created a second installation of the printer, which I later deleted, and everything is fine.

Very good printer for economical printing.
The package includes 3 black pigment inks and 3 color inks. During installation, only one black ink is used, so the other two are left for future use.

The installation was easy, but its screen will appear small to many and does not light up. You can now print through a computer or mobile/tablet, so it was not a problem for me. It also has clear instructions inside to get started.

It does not have an ADF for automatic scanning of multiple pages, but it has automatic double-sided printing, which is very convenient. Also, the paper feed is through a cassette or from the back of the printer.

I will also print photos (with the appropriate photo paper) to see the quality of the prints.
