Printers - Dot matrix

Dot Matrix Printers - 9 pin, 18 pin, 24 pin and 36 pin

Dot matrix printers use a moving print head with pins that strike an ink ribbon to form characters and graphics from tiny dots. This impact method enables multipart forms, continuous fanfold paper and carbon copies, making them a long-standing choice for industrial, retail and office environments in South Africa.

Why dot matrix printers are still in use

• Impact printing - allows carbon copies and multi-layer forms in a single pass
 
• Continuous paper - suited for invoices, statements and delivery notes
 
• Low running cost - long-lasting ribbons and minimal consumables
 
• Durable - reliable in dusty, hot and demanding industrial conditions
 
• Business friendly - ideal for retail counters, banks, logistics and factories

Pin configurations explained

• 9 pin printers: Entry-level impact printers offering fast draft quality text. Coarse dot density, good for receipts, tickets and simple forms.
 
• 18 pin printers: Improved clarity over 9 pin while maintaining good speed. Balanced option for mid-volume printing of forms and reports.
 
• 24 pin printers: Higher density output suitable for clearer text and better graphics. Delivers near-letter-quality documents for official paperwork.
 
• 36 pin printers: Heavy-duty models combining high pin count and reliability. Best suited for high-volume workloads requiring both speed and clarity.

Limitations

• Lower resolution compared to inkjet or laser printers
 
• Noisy operation due to impact printing process
 
• Slower printing speeds when higher quality modes are used

Common applications

• Invoices, purchase orders, delivery notes and dispatch documents
 
• Banking and retail counters requiring multipart forms
 
• Warehousing and logistics - continuous labels and lists
 
• Industrial environments where durability and low costs are key

Buying considerations for South Africa

• Select pin count based on quality needs - 9 and 18 pin for speed and low cost, 24 or 36 pin for better clarity
 
• Check multipart support - maximum number of carbon copies per pass
 
• Ensure correct connectivity - USB, network or legacy serial/parallel as needed
 
• Allow physical space for continuous fanfold paper handling
 
• Plan placement - dot matrix printers are noisier than modern printers
