How to remember which cartridge fits your printer
Cartridge names often differ by a single letter or digit, and each only fits certain printer models. In a shop it is easy to mix up 305, 305XL or something similar.
Save the printer model, the exact cartridge number and a photo of the packet in Specsy — and next time it is obvious what to buy.

A numbering system that is easy to get wrong
Cartridge names are short and very much alike: standard and high yield versions, different letters and digits, and sometimes separate variants for different regions.
And they are bought rarely. Over a few months it is easy to forget not only the cartridge number but the exact printer model as well.
The result is a cartridge that is almost the right one, opened, and only then found not to fit your printer.
What to write down
- The exact printer model — in full, as printed on the body or the label
- Every cartridge that fits — black and colour, standard and high yield
- The page yield of each — so you compare the cost of printing, not just the price of the box
- Whether there is an ink subscription — it changes what is worth buying separately at all
- A photo of the old cartridge — with the number clearly visible, so it never has to be recalled
Why the letters and markings matter
Every manufacturer has its own naming system, but the logic is usually similar. One extra letter or marking can mean a different capacity, a different region, or a different type of cartridge altogether.
| Marking | What it usually means | What to watch for |
|---|---|---|
| No suffix | Standard capacity | Usually cheaper to buy, but a lower yield |
| XL | High capacity | Costs more, but prints more pages |
| A region letter, for example A | Version for a particular market | May not fit printers from another region |
| Setup / Starter | The starter cartridge from the box | Often not sold separately |
So it is better to save the full marking, not just the number.
Compare price per page, not just the price of the cartridge
A cheaper cartridge does not always work out cheaper. A high yield version costs more, but often holds a great deal more ink.
With the price and the rough page yield saved on the card, a few seconds in the shop are enough to see which option is genuinely better value.
Questions people ask
Does Specsy check compatibility itself?
No. Specsy does not try to work out which cartridge fits your printer. It stores the number you have already used and know for certain fits. For a purchase you make rarely that is often more useful than any database: instead of researching compatibility again, you simply repeat what already worked.
Can I keep a note about third party cartridges?
Yes, and it is worth it. If a compatible brand worked, write the brand down. If one leaked, write that down too.
What about toner rather than ink?
Same card, same fields. Toner numbers are just as easy to confuse and a wrong one costs more.
