If you want really good caliber ink you should look for the ISO-9001 sign on the suppliers web site. The ISO logo is worth seeing on all the printer ink products because that will ensue that you are getting a good quality item. The ISO do not just give out certifications to all and sundry. The factory gets audited and inspected on a regular basis. When you see that sign of certification you can be sure that online supplier is prudent to send you good product and will have good after sales service. I would suggest that you always order your printer ink supplies from a online supplier that has a full satisfaction guarantee. It is easy to change from original ink to generic once you have located a good online supplier.
