Introduction
Wondering should you leave printer on all the time or turn it off when not in use? This common question confuses millions of printer owners worldwide.
The debate about should you leave printer on involves two important factors: electricity costs and printer health. Some experts say leaving printers on wastes energy. Others warn that turning them off damages printheads.
Understanding should you leave printer on helps you make the right choice for your situation. The answer isn’t the same for everyone—it depends on your printer type, usage patterns, and priorities.
This complete guide reveals the truth about should you leave printer on decisions. You’ll discover exactly how much power your printer uses, how on/off cycles affect printheads, and what printer manufacturers actually recommend.
By the end, you’ll know exactly what’s best for your printer and your budget. Let’s settle this debate once and for all.
What Does Leaving Your Printer On Mean for Performance and Costs?
When asking should you leave printer on, you’re really asking about balancing three things: energy costs, printer lifespan, and print quality.
Modern printers have different power modes:
Active mode runs when actually printing. This uses the most power—typically 30-50 watts for inkjet printers and 300-600 watts for laser printers.
Ready mode keeps the printer warmed up and ready. Power usage drops to 5-15 watts for inkjets and 30-100 watts for lasers.
Sleep mode reduces power to 1-3 watts while maintaining quick wake-up capability.
Off mode uses zero power but requires warm-up time when restarted.
The question should you leave printer on matters because printheads need moisture. Inkjet printers especially face dried ink problems when turned off too long.
Laser printers don’t have this issue because they use toner powder, not liquid ink.
Energy consumption adds up. A printer left in ready mode 24/7 costs about $10-30 annually in electricity. That might seem small, but multiply it across multiple printers or years of use.
Printhead replacement costs $30-100, often more than the annual electricity savings from turning printers off.
The real answer to should you leave printer on depends on your printer type and how often you print.
6 Key Factors to Decide Should You Leave Printer On
Factor 1: Should You Leave Printer On Based on Printer Type?
Your printer type heavily influences should you leave printer on decisions.
Inkjet Printers:
Inkjet models face the biggest risks from being turned off. Here’s why:
- Ink dries in printheads when printers sit off for days
- Dried ink clogs nozzles and damages printheads
- Cleaning cycles consume expensive ink
- Replacement printheads cost more than energy savings
For inkjets, the answer to should you leave printer on is usually YES if you print weekly or more.
Turn off only during extended absences (2+ weeks).
Laser Printers:
Laser printers use toner powder, not liquid ink.
- No printhead drying issues
- Consume more power in ready mode
- More durable internal components
- Handle on/off cycles better
For lasers, you can confidently turn them off when not in use. The answer to should you leave printer on for lasers is usually NO.
All-in-One Printers:
These combine printing with scanning and copying.
- Follow inkjet rules if they use ink
- Consider how often you use scan/copy features
- Frequent scanning might justify leaving on
Your printer type provides the biggest clue about should you leave printer on decisions.
Factor 2: Should You Leave Printer On Depending on Usage Frequency?
How often you print dramatically affects should you leave printer on choices.
Daily Users (Print 5+ days per week):
Definitely leave your printer on. Here’s the logic:
- Printer stays ready instantly
- Fewer startup cycles mean less wear
- Printheads stay moist and healthy
- Minimal energy waste compared to constant cycling
For daily printing, should you leave printer on? Absolutely YES.
Weekly Users (Print 1-4 days per week):
This is the gray area for should you leave printer on.
For inkjets: Leave on in sleep mode For lasers: Turn off between uses
Weekly users save energy by turning off lasers but risk printhead damage by turning off inkjets.
Occasional Users (Print monthly or less):
Even occasional users with inkjets should leave them on.
- Set to deep sleep mode
- Schedule automatic cleaning cycles
- Power usage stays under 5 watts
The cost of one printhead replacement exceeds five years of sleep mode electricity.
For rare printing, should you leave printer on? Yes for inkjets, no for lasers.
Factor 3: Should You Leave Printer On for Printhead Health?
Printhead maintenance is crucial when deciding should you leave printer on.
How printheads stay healthy:
Printers left on perform automatic maintenance cycles. These happen every 12-48 hours depending on the model.
Maintenance includes:
- Tiny ink bursts through nozzles
- Printhead cleaning sequences
- Ink recirculation to prevent settling
These cycles prevent clogs and extend printhead life.
When you turn printers off:
All maintenance stops. Ink sits motionless in tiny tubes and nozzles. Evaporation begins within hours.
After 3-5 days off, dried ink forms. After 7-10 days, clogs become serious. After 2+ weeks, damage might be permanent.
Professional repair shops report that 60% of printhead failures result from printers being turned off too frequently.
The verdict on should you leave printer on for printhead health:
Yes for inkjets. Automatic maintenance justifies the minimal electricity cost.
Factor 4: Should You Leave Printer On Considering Energy Costs?
Money matters when deciding should you leave printer on.
Real power consumption numbers:
Inkjet printer in sleep mode: 2-3 watts
- Annual cost: $2-4 (at $0.13/kWh)
- Barely noticeable on electric bill
Inkjet in ready mode: 8-12 watts
- Annual cost: $8-15
- Still very affordable
Laser printer in sleep mode: 5-10 watts
- Annual cost: $5-12
- Reasonable for convenience
Laser in ready mode: 50-100 watts
- Annual cost: $60-120
- Significantly higher
Compare to replacement costs:
Inkjet printhead replacement: $40-100 Deep printhead cleaning service: $30-60 New inkjet printer: $50-200
A single printhead replacement costs more than 10-25 years of sleep mode electricity.
Financial answer to should you leave printer on:
For inkjets: Leave on—saves money long-term For lasers: Turn off—saves money without risk
Factor 5: Should You Leave Printer On for Environmental Impact?
Environmental concerns influence should you leave printer on decisions.

Common Mistakes When Deciding Should You Leave Printer On
Don’t apply laptop logic to printers. Many people treat printers like computers—turning them off to “rest” them. Printers aren’t computers. They need different treatment, especially inkjets that require constant moisture control.
Don’t turn off printers during short vacations. Going away for a week? Leave inkjet printers on. The electricity cost is under $0.50, while printhead cleaning costs $30-60. For trips over two weeks, print a test page before leaving to purge printheads, then turn off.
Don’t disable all power-saving features. Some users disable sleep mode thinking it causes problems. Sleep mode is designed specifically to balance energy savings with printhead health. Keep it enabled for optimal should you leave printer on results.
Don’t forget about power surges. If you decide to leave your printer on, use a surge protector. Power spikes damage printer electronics. A $15 surge protector prevents $100+ in printer repairs.
Don’t ignore your printer’s specific recommendations. Check your printer manual for manufacturer guidance on should you leave printer on. Some models have unique requirements that override general advice.
Don’t leave printers on during thunderstorms. Even with surge protection, direct lightning strikes can destroy electronics. Turn off and unplug printers when severe storms approach.
Don’t block printer vents. If leaving your printer on, ensure proper ventilation. Printers generate heat during maintenance cycles. Blocked vents cause overheating and component failure.
Frequently Asked Questions About Should You Leave Printer On
Q1: Should you leave printer on when going on vacation?
For vacations under two weeks, leave inkjet printers on in sleep mode. The small electricity cost (under $1) prevents expensive printhead damage. For longer trips over three weeks, print a cleaning page to purge printheads, then turn off and unplug. Laser printers can be turned off for any vacation length without issues.
Q2: Does leaving your printer on waste a lot of electricity?
No. Modern printers in sleep mode use only 1-3 watts—similar to a single LED light bulb. The annual cost is typically $2-5 for inkjets. This minimal cost is far less than replacing dried-out printheads. When considering should you leave printer on, electricity waste is not a valid concern for inkjets in sleep mode.
Q3: Will leaving my printer on all the time shorten its lifespan?
Actually, the opposite is true for inkjets. Leaving them on extends lifespan by preventing printhead damage and reducing startup stress on components. Power surges during startup cause more wear than continuous operation in sleep mode. For lasers, turning off between uses slightly extends lifespan, but the difference is minimal.
Q4: Should you leave printer on if you only print once a month?
Yes for inkjet printers. Even with rare printing, the automatic maintenance cycles prevent printhead clogs. The monthly electricity cost is under $0.50.
