One hint would be the scope of delivery, this printer has one ink cartridge for colour and black, i.e. there are no individual colours included. Unfortunately, the task of finding a cheap printer can be answered very simply: inkjet printers are never cheap. They are actually only exciting for the manufacturers, because the small amount of ink you get in the individual cartridges is expensive in any case. But there is hope, because these printers use ink tanks and not ink cartridges, so they are very cheap to run. The purchase is a little more expensive, but the bottom line is that you only need to buy ink tank bottles later, which is also an advantage for the environment, because there is less waste.

The Canon PIXMA TS5351a model does not use individual colour ink cartridges, but a combined colour cartridge and a separate black ink cartridge. The colour cartridge and black ink cartridge are included, but there are no specific numbers for individual colours as the colours are combined in one cartridge.

In general, I have found that the cartridges are empty extremely quickly.

If the book is not too thick, you can open it completely and lay it flat on the glass. The printer cover will not close properly, but this does not prevent copies from being made.

Yes, Cannon also provides drivers for macOS 12 (Monterey) on the corresponding website. Helpful: Search the web for "Canon PIXMA TS5351a service". Detailed information on the product, installation and use is available.

You should find exact specifications for both models at https://www.canon.de/printers/pixma-ts5350-series/specifications/ and https://www.canon.de/printers/pixma-ts5350a-series/specifications/. Most of the features are identical. The only difference I have noticed so far is the display size. The TS535 is also listed as not available from Canon and should be somewhat older according to our information (on sale since 2019). We have been offering the A model since May 2022.

The TS5351 is black, the TS5351a is white. The TS5351 also has Mopria Print Service as "Printing Technology". TS5351a has an Ethernet connector, which is missing on the TS5351. I also noticed the price difference, I bought the TS5351a. Price differences can have many causes, I assume production batches, purchase timing, purchase quantities and stock levels play a role. The TS5351a should be newer and cheaper to buy, the part number is in any case much higher than the TS5351. (For such tricky differences, a query via an internet search engine is usually the quickest). Have fun with the printer!
