I’m sorry, but as of my last knowledge update in January 2022, I don’t have specific information about the Canon GI790 PIXMA Magenta Ink Bottle. Product details, including model numbers, can change, and new products may be introduced.

However, based on the naming convention, it’s likely that the Canon GI790 is designed for use with Canon printers and contains magenta ink. It would typically be part of Canon’s Ink Tank system, offering efficient and cost-effective printing, especially for users with high-volume printing needs.

For the most accurate and up-to-date information, I recommend checking the official Canon website or contacting Canon customer support to inquire about the GI790 Ink Bottle and its compatibility with specific Canon printer models.
