Pros & Cons
👍 Pros
- Produces smooth tonal transitions in highlight and midtone areas of photographic prints
- Smart LED indicator makes it easy to monitor remaining ink levels at a glance
- Optimized for use with Canon genuine photo papers for accurate color reproduction
- Individual ink tank means you only replace the light gray when it runs out, not an entire multi-color cartridge
👎 Cons
- Compatible only with the Canon PIXMA Pro-100, limiting use to a single printer model
- Page yield of approximately 180 pages is relatively low for frequent printing
- Higher per-cartridge cost compared to third-party alternatives
- Part of an eight-ink system, so maintaining a full set of CLI-42 cartridges adds up in expense
