305

Hi! I can help you choose between HP 305 and 305XL, or walk you safely through a cartridge or printer problem. For a fault, please mention your exact printer model and the error message.

Answers come from a checked local knowledge base. Please don't share personal data or serial numbers.

Note: this assistant doesn't use a language model. It matches your question to a checked answer by keyword, so it can't make up prices, stock levels or test results.

Check your printer → 305 or 305XL → Pick a problem →

Please note: this is general information, not an official HP diagnosis. Stop if ink is leaking, the cartridge is visibly damaged or there's an unusual smell, and contact HP or the retailer.
