Multi-Printer Routing Explained
What multi-printer routing is, how it works, and when it makes sense for your business.
Last updated: February 2026
What is multi-printer routing?
Multi-printer routing is exactly what it sounds like: instead of sending every packing slip to one printer, you set up rules that decide which printer gets which order. It's the difference between having one checkout lane and having five.
You define the rules -- maybe orders over $500 go to the printer near your secure packing area, Amazon orders go to a dedicated station, or you just split the load evenly across two printers. The system follows those rules automatically for every order.
Why a single printer stops being enough
A single printer works great up to a point. If you're doing 30-50 orders a day, one printer can keep up and everyone grabs slips from the same spot. Simple.
But things change as you grow:
- Bottleneck -- One printer can only go so fast. During a busy day, people end up standing around waiting for slips to come out.
- Single point of failure -- If that printer jams, runs out of ink, or goes offline, everything stops. No slips, no packing, no shipments.
- Physical distance -- If your packing area grows or you add a second location, walking back and forth to one printer wastes time.
- Mixed workflows -- Different types of orders might need different handling. High-value items might need to be packed in a specific area. Amazon orders might have different requirements than your Etsy shop.
Multi-printer routing solves all of these by letting you spread the work across multiple printers with rules that match your actual workflow.
Routing strategies
SPConnector offers four routing strategies. You pick the one that fits your operation, or combine them with custom rules.
Round-Robin
Orders are split evenly across your printers. Printer A gets the first order, Printer B gets the second, back to Printer A for the third, and so on. This is the simplest way to double (or triple) your throughput. No special rules, just balanced distribution.
Good for: Two or more printers in the same area where you just want to print faster.
Failover
You designate a primary printer and one or more backups. Orders go to the primary printer. If it goes offline (paper jam, ink runs out, someone trips over the cable), orders automatically switch to the backup. When the primary comes back online, it picks up where it left off.
Good for: Making sure orders keep printing even when something goes wrong. Especially useful if you can't afford downtime during busy periods.
Rule-Based
You write rules that match orders to specific printers based on order details. You can route based on order value, shipping method, destination state, marketplace, or any combination. Rules are checked in order, and the first match wins.
Good for: Complex operations where different orders need different handling -- geographic routing, marketplace segmentation, or value-based sorting.
Print-to-All
Every order prints on every printer. This sounds redundant, but it's useful for specific situations -- like when you need a copy at the packing station and another at the shipping desk, or when high-value orders need a copy in the secure area.
Good for: Orders that need physical copies at multiple locations, or when different teams need the same slip at the same time.
Real-world use cases
Geographic routing
If you ship from multiple locations, you can route orders to the printer closest to where they'll be packed. East coast orders print at the east coast warehouse, west coast orders at the west coast facility. The person packing those orders doesn't need to sort through irrelevant slips.
Marketplace segmentation
Sell on both Amazon and Etsy? Amazon orders might have different packing requirements or go through a different fulfillment process. Route Amazon orders to one printer and Etsy orders to another, and each team handles their own stack.
Value-based routing
High-value orders (say, anything over $500) can automatically route to a printer in your secure packing area. These orders might need extra care, insurance, or specific packaging. Having them print in a dedicated spot means they get the attention they need.
Department routing
If different product categories are packed in different areas of your warehouse, route orders to the printer nearest to where those products are stored. Electronics go to one station, clothing to another, and bulky items to a third.
How to choose the right strategy
Pick based on what problem you're solving:
- "My printer can't keep up" -- Start with round-robin. Add a second printer and split the load. Done.
- "I can't afford printing downtime" -- Use failover. Designate a backup printer so you never stop shipping because of a printer issue.
- "Different orders need to go to different places" -- Use rule-based routing. Set up conditions for each type of order and point them to the right printer.
- "I need copies at multiple spots" -- Use print-to-all for the orders that need it.
You can also combine strategies. For example, use rule-based routing for high-value orders with a failover fallback for everything else.
Getting started with multi-printer routing
Multi-printer routing is available on the Business plan (2 printers) and Enterprise plan (unlimited printers). Here's how to set it up:
- Make sure you have PrintNode installed on each computer connected to a printer
- Add your PrintNode API key to SPConnector (all printers under that account show up automatically)
- Go to your multi-printer configuration and select which printers to use
- Pick a strategy and set up any rules you need
- Test with test mode enabled to make sure orders route where you expect
If you're not sure which setup is right for you, our support team can help you figure it out.
