If you have just refilled a cartridge and are having problems getting it to print properly check to make sure that you didn't cause a vapor lock problem by sealing breather holes or refilling holes. Exception, of course, to cartridges profiled above.

Epson cartridges generally work well with refill holes uncovered if it was refilled from top. The new design of Epson cartridges is very confusing. These are new skinny ones like T04xx and T08xx series of cartridges. The OEM cartridges are comprised of a series of chambers. They are harder to refill than their generic counterparts and some instructions will tell you to drill top and others will tell you to drill in bottom. Sealing top hole is not mandatory while sealing bottom is a must. Some generic versions of these cartridges are sponge filled and are far simpler to refill. You can drill on top without complication and you don't have to reseal.

So bottom line is if you are having printing problems after you refill be sure you have not caused problem by sealing cartridge and creating a vapor lock.

A fascinating aspect of Bluetooth-enabled devices is their ability to communicate with each other spontaneously when they come within each other's range. A Bluetooth-enabled cell phone can be configured so that it can automatically print out all its stored messages and photos using a Bluetooth printer as soon as you enter your office without any manual intervention.

Another advantage of using Bluetooth is its support for point-to-multipoint communications. This means a single printer can simultaneously connect to both your cell phone, as well as your computer and any other Bluetooth enabled device within its vicinity.

The HP 995c Bluetooth printer is one example of an inkjet printer with built-in Bluetooth support.

Here is an excerpt from a review of HP 995c done by PC Magazine: http://www.pcmag.com/article2/0,1759,10381,00.asp

"We found we could print wirelessly from as far away as 40 feet. And we found no significant difference in output speed between printing via a USB connection and printing wirelessly with Bluetooth."

Bluetooth is still in its infancy but from what I've seen so far it looks like it will be dominant wireless technology in future.
