Our review

The essential to remember

The Canon Pixma GM4050 is a cartridgeless printer, similar to the Pixma G7050. It differs from it by offering only monochrome printing and by abandoning its fax function. However, it keeps its document feeder (CAD) with a capacity of 35 sheets, which differentiates the G7050 from the G6050 tested on

The Pixma GM4050 retains the impressive size of its color counterpart (40.3 x 36.9 x 23.4 cm with the shutters closed) and its control panel is rudimentary. Fortunately, it also returns to its very low cost per page in black and white (0.3 euro cents). It's even better than a laser printer, but its print speeds are not comparable (we noted about 7 pages per minute (ppm), and 4 ppm in automatic duplex mode during our test of the G6050). These relatively low speeds are tolerable for the color printers of the range, which manage to compensate for this defect by offering good quality photo printing - an area where laser printers are struggling to compete. Not taking advantage of this quality, the GM4050 will have to face competition from this technology.


Like the Pixma G6050 and other printers in the range, the GM4050 benefits from many qualities. In addition to its ridiculous cost per page, it turns out to be a printer that does everything. We regret, however, a control panel that stains in view of its high price. The investment in a GM4050 can nevertheless be quickly amortized compared to a conventional inkjet and its healthier economic model should appeal to those who are in their umpteenth cartridge printer.
