But when is an inkjet printer the right choice? How do the different models and technologies differ? And what should you look out for when buying to ensure printing is not only cheap initially but also affordable in the long run?

This guide answers your most important questions about inkjet printers. We explain how they work, highlight the pros and cons compared to laser printers, and provide practical tips for the optimal use and care of your device.

1. What is an Inkjet Printer? Function and Technology Explained

The basic principle common to all inkjet printers is already in the name: They create a printed image by precisely "spraying" tiny droplets of liquid ink onto paper or another print medium. However, different technical approaches and components lie behind this.

• 1.1 Print Head Technologies: How does the ink actually get onto the paper? This involves the heart of printing, the print head with its extremely fine nozzles. There are mainly two methods for ejecting ink from these nozzles:
  

• Thermal Process (Bubble-Jet): Tiny heating elements in the nozzle chambers heat the ink very quickly. This creates a small vapor bubble that forces an ink droplet out of the nozzle under pressure. In this method, the print head is often integrated directly into the ink cartridge and is replaced with each cartridge change. This can simplify maintenance, as a potentially dried-out or defective print head is simply disposed of with the cartridge. Canon and HP frequently use this method.
  

• Piezoelectric Process: This uses piezo crystals that deform under electrical voltage. This deformation mechanically generates the pressure that pushes the ink out of the nozzle. Piezo print heads are generally more durable and permanently installed in the printer. Only the ink tanks or cartridges are replaced. This method usually allows for more precise control over droplet size and is often used by Epson.
  
  
• 1.2 Ink Types: The type of ink used significantly impacts the print result, durability, and cost. The following types exist:
  

• Dye-Based Ink (Dye Ink): The colorants are completely dissolved in the carrier fluid. These inks produce very brilliant, vibrant colors and a wide color gamut, which is particularly advantageous for photo prints on special glossy paper. Disadvantages include lower UV resistance (colors can fade faster) and lower water and smudge resistance on plain paper.
  

• Pigment-Based Ink (Pigment Ink): Here, solid, very fine color pigments are suspended in the carrier fluid. Pigment inks are significantly more light-resistant, water-resistant, and smudge-resistant, even on plain paper. They are excellent for long-lasting documents and offer very sharp text quality. However, color brilliance on glossy paper might be slightly lower than with dye inks. Many printers use a combination: Pigmented black for sharp text and dye-based color inks for brilliant images, combining the best of both worlds.
  

• 1.3 Color Management: How are colors mixed in the printer? Most color inkjet printers operate on the CMYK color model. They use four primary colors from which almost all other shades are created by mixing:
  

• Cyan (Blue-green)
• Magenta (Purple-red)
• Yellow
• Key (Black – often a separate cartridge for deep black text)
  

For even better photo quality, especially for skin tones and fine color gradients, dedicated photo printers often use additional inks, such as Light Cyan, Light Magenta, Gray, Red, Green, or Blue.

• 1.4 Ink Supply: Cartridges or Tanks? Traditionally, inkjet printers use individual ink cartridges. Inexpensive models often have just one black cartridge and one tri-color combination cartridge. If one color runs out in the combo cartridge, the entire cartridge must be replaced, even if the other colors are not yet depleted – this is uneconomical. Printers with individual ink cartridges for each CMYK color (or more) are better. Here, you only replace the color that is actually empty.

An important trend in recent years is ink tank printers (known by names like Epson EcoTank, Canon MegaTank, HP Smart Tank). Instead of small cartridges, these printers have large, refillable ink tanks. The ink is replenished from inexpensive bottles.

• Advantages: Extremely low cost per page, less waste from empty cartridges, high yield per fill.
• Disadvantages: Higher initial purchase price of the printer. Refilling can be slightly messy if not handled carefully.
  
  
  

2. Strengths and Weaknesses: The Pros and Cons of Inkjet Printers

Like any technology, inkjet printers have their specific advantages and disadvantages:

• 2.1 Advantages:
  

• Excellent Color and Photo Quality: Especially for photo prints on suitable paper, they usually deliver more brilliant and detailed results than laser printers.
  

• Versatile Media Support: Inkjet printers can print on a wide range of paper types and weights, including photo paper, labels, transparencies, envelopes, and sometimes even CDs/DVDs or textiles.
  

• Lower Purchase Costs: Basic inkjet printers are often significantly cheaper to buy than laser printers.
  

• Compact Design: Many models are relatively small and space-saving.
  

• Borderless Printing: Most models support borderless printing, ideal for photos.
  

• Lower Power Consumption (During Printing): During the printing process, they usually consume less energy than comparable laser printers.
  

• 2.2 Disadvantages:
  

• Higher Printing Costs Per Page (with Cartridges): The cost of original ink cartridges is often high, leading to high page prices, especially with frequent printing. Ink tank printers are an exception!
  

• Slower Print Speed: They are often slower than laser printers, especially when printing plain text documents, although so-called business inkjet printers are catching up.
  

• Sensitivity of Prints: Pages printed with standard dye-based inks can smudge when exposed to moisture and are less UV-resistant.
  

• Risk of Drying Out: If not used for extended periods, the fine nozzles in the print head can dry out and clog. Regular use or automatic cleaning cycles are therefore necessary but consume ink.
  

• Ink Shelf Life: Unopened cartridges have an expiration date, and even opened cartridges can age.
  
  
  

3. Inkjet vs. Laser: Which Printer Suits You Better?

The decision between an inkjet and a laser printer depends heavily on the individual usage profile:

• Choose an Inkjet Printer if:
• You want to print in color regularly or occasionally, especially high-quality photos or graphics.
• You want to print on a wide variety of paper types or media.
• The purchase price plays an important role.
• You only have a low to medium print volume (or are considering an ink tank printer for higher volumes).
• A compact device is desired.
  

• Choose a Laser Printer if:
• You primarily print text documents in black and white and value high speed and razor-sharp text.
• You have a high monthly print volume, as the cost per page for lasers is often lower.
• The prints need to be immediately smudge- and water-resistant.
• The printer might stand unused for longer periods.
• The slightly higher purchase costs are less of a concern.
  
  
  

4. Making the Right Choice: Important Buying Criteria for Inkjet Printers

To find the optimal inkjet printer for you, you should pay attention to the following features:

• 4.1 Printer Type (Printer vs. Multifunction Device): Do you only need the print function, or also an integrated scanner and copier? Multifunction printers (MFPs), often called All-in-Ones (AIOs), are extremely practical for home offices and private users as they combine multiple devices in a space-saving way.
  

• 4.2 Print Quality & Resolution: This is specified in DPI (Dots Per Inch). Higher values potentially mean finer details. 600x600 dpi is often sufficient for text. For good photos, it should be at least 1200x1200 dpi, preferably 2400x1200 dpi or even higher (e.g., 4800x1200 dpi, 5760x1440 dpi). Note that perceived quality also depends on the ink and paper.
  

• 4.3 Print Speed (ISO IPM): Look for standardized specifications in IPM (Images Per Minute) according to the ISO standard, as these are more comparable than the often optimistic PPM (Pages Per Minute) figures from manufacturers. Separate values are given for black and white and color printing. Moderate speeds are often sufficient for home use; faster models (15+ IPM B/W) are useful in the office.
  

• 4.4 Running Costs (Ink): This is a crucial point!
  

• Cartridges vs. Ink Tanks: Compare the printer's purchase price with the subsequent costs for ink. Ink tank printers are more expensive initially but have extremely low page prices and quickly pay off with higher print volumes.
  

• Page Yield (ISO): Pay attention to the specified yield of cartridges/ink bottles according to the ISO standard.
  

• Number of Cartridges: Individual color cartridges are more economical than combined cartridges.
  

• Original vs. Compatible / Refill: Original ink offers the highest reliability and quality. Compatible cartridges from third-party suppliers or refill ink can save costs but carry risks regarding quality & compatibility. While using them might not automatically void the manufacturer's device warranty, consequential damage caused by third-party ink is often not covered.
  

• 4.5 Paper Management:
  

• Paper Formats: Standard is DIN A4. Do you also need larger formats like A3 or A3+ as a graphic designer or photographer?
  

• Paper Trays: How many sheets fit in the main cassette (e.g., 100, 250 sheets)? Are there additional trays for photo paper or envelopes? A manual feed for special media?
  

• Automatic Duplex Printing: Can the printer automatically print on both sides? This saves paper and time.
  

• ADF (Automatic Document Feeder): Very practical on multifunction printers for automatically scanning or copying multi-page documents.
  

• 4.6 Connectivity: How do you connect the printer?
  

• USB: Standard port for direct connection to a computer.
  

• Ethernet (LAN): For integration into a wired network (stable and often used in offices).
  

• WLAN (Wi-Fi): Standard for wireless printing on the home network from various devices (PCs, laptops, smartphones, tablets). Look for current Wi-Fi standards.
  

• Wi-Fi Direct: Allows a direct wireless connection between the device and printer without going through the router.
  

• Mobile Printing: Support for manufacturer apps, Apple AirPrint, Mopria Print Service, etc., for easy printing from mobile devices.

• 4.7 Size, Operation & Noise: Does the printer fit in the intended space? Is operation via buttons or a (touch) display simple and understandable? How loud is the printer during operation?
  

• 4.8 Special Features: Do you need special functions like borderless photo printing, the ability to print directly onto CDs/DVDs, or support for very thick paper or special media?
  
  
  

5. Inkjet Printers for Every Purpose: Application Areas & Recommendations

Based on the criteria, typical profiles can be outlined:

• 5.1 For Home Users (Everyday, School): An inexpensive to mid-range multifunction device is often ideal. 8-12 IPM B/W is usually sufficient. Individual ink cartridges or even an entry-level ink tank printer can be worthwhile if printing regularly. Wi-Fi connectivity is standard. Good all-around print quality is important.
  

• 5.2 For the Home Office: A reliable multifunction device with automatic duplex printing and ideally an automatic document feeder (ADF) for scans/copies is highly recommended. A slightly higher print speed (12-15+ IPM B/W) is advantageous. Ink tank printers are particularly attractive here due to low running costs. Good connectivity (WLAN, possibly Ethernet) and ease of use are important. Pigmented black for document-proof text is a plus.
  

• 5.3 For Photography Enthusiasts: Dedicated photo printers are the best choice here. They usually use more than four inks (e.g., 6-10 colors, often pigment-based for longevity) for a wider color gamut and finer gradations. They offer very high resolutions, support special photo papers in various formats (often A3+ as well), and perfectly master borderless printing. Print speed is often secondary here, as quality takes precedence.
  

• 5.4 For the Office (Smaller Teams/Departments): So-called business inkjet models offer high speeds (often 20+ IPM), large paper capacities, duplex print/scan, and are designed for higher monthly print volumes. They often use pigmented inks for document-proof prints and can be an energy-efficient alternative to color laser printers. Network capability (Ethernet, WLAN) and management functions are important here. Ink tank systems are also very economical in this segment.
  
  
  

6. Commissioning, Care & Troubleshooting: Keeping Your Printer Running Smoothly

To ensure you enjoy your inkjet printer for a long time, several points should be observed:

• 6.1 Installation & Setup: Follow the manufacturer's instructions. Above all, install the latest drivers and associated software. For more convenience, connect the printer to your Wi-Fi network. A LAN or USB connection offers more stability.
  

• 6.2 Regular Use & Maintenance: The key with inkjet printers is regular use to prevent ink from drying in the nozzles. Print a test page or a small document (including color) at least once a week. Use the printer's automatic cleaning programs when needed. Manual cleaning options are often available via the printer software.
  

• 6.3 Handling Ink & Paper: Use high-quality ink (ideally original ink or good quality compatible products from reputable suppliers to minimize risks) and paper suitable for the purpose. For photos, special photo paper is essential for good results. Store paper dry.
  

• 6.4 Common Problems & Solutions:
  

• Dried Nozzles/Streaky Printing: Run a print head cleaning cycle via the software (possibly multiple times). For stubborn cases or permanent print heads, special cleaning fluids exist (use at your own risk!).
  

• Paper Jam: Carefully remove the jammed paper in the direction of travel. Check for paper fragments. Do not use paper that is too thick, too thin, or creased. Load paper correctly.
  

• Poor Print Quality: Check the ink level, run a print head cleaning, and possibly a print head alignment. Use the correct paper and appropriate print settings (quality mode).
  

• Printer Not Recognized: Check the cable connection or Wi-Fi connection. Restart the printer and computer. If necessary, reinstall the driver.
