In this review the Pitney Bowes SL-798-0 red ink cartridge is evaluated for small offices and mailrooms that need consistent, legible postage prints. The bottom line: this 17 ml cartridge is designed specifically for Pitney Bowes SendPro C and SendPro+ meters and delivers up to 1500 impressions per cartridge, making it a practical choice where postage readability and uptime matter more than bargain pricing.

Key Features

• Engineered for Pitney Bowes: Formulated to meet or exceed mail requirements and ensure compatibility with SendPro C and SendPro+ postage meters.
• Up to 1500 impressions: Optimizes the number of envelopes printed per cartridge so small business mail runs require fewer mid-day changes.
• Readable when wet: Ink stays legible even under light moisture, helping avoid misdirected or delayed mail due to smudging.
• Consistent performance: Tested in millions of cycles to provide reliable, repeatable print quality across an entire cartridge life.
• High contrast red: Provides clear, professional postage marks that remain easy to read for postal sorting systems and recipients.

Who It's For

The SL-798-0 is best for small businesses, retail counters, or internal mailrooms that use Pitney Bowes SendPro C or SendPro+ meters and need dependable, readable postage without frequent cartridge swaps. It suits operations that value compliance with mail standards and a cartridge that will not dry out quickly.

It is less appropriate for users who do not operate Pitney Bowes meters or who need very high-volume industrial throughput beyond the stated impressions per cartridge; those users should consider larger-capacity solutions or meter models intended for heavy production environments.
