What's the difference between a 9 pin and a 24 pin printer?
1272589
Print quality. More pins = finer density/better quality. It is a reference to the print head in the device.

That is the number of pins in the printhead that strike the page to create the character. The more pins the better the quality and usually faster.

I only own the 2540, but just scanning the specs, it seems as if the 2542 is faster. I can't see any other notable difference: both offer wireless connectivity and the ability to do basic printing jobs as well as scanning and copying. They use the same inks, and the printing & scanning resolution seems similar. You may want to ask HP what the differences between them are (vs whether they are basically the same device). The paper feed on the 2542 may be different? But I can't tell without having one here, and suspect that many others out there own either one or the other but not both, and so may have a tough time addressing this question.

Don't know. Have only connected a small laser printer using the provided software, so haven't even had to use both ports.

Dual 4 pin. I currently have it in a older HP machine. Only 1 of the 4 pins plugged in, working fine.

The answer depends on whether the printer is connected directly to your PC or if the printer is on a network. The network speed will be a major factor in the printing speed.

I just upgraded my 8600 plus to the 8620 today and have aleady noticed alot of little enhacements. The automatic document feeder is more reliable and handles larger loads. Duplex printing is much faster. The output tray is less sticky and doesn't jam as easily when you pull it out.

According to Netgear website the difference between DGND3700v1 and DGND3700v2 is very minor. It seems like USB specifications has been updated to allow wider choice of printers to use for ReadySHARE.

23 ga pins are more common, come in more sizes, and are more discreet. 21 is better for production. Whatever you do, DONT BUY A Grex. Look at fasco, senco and porter cable

I sell these printers for a living. The main difference between the 8625 is it comes with a usb cable. Same software and drivers.

It does have a 9 pin serial port and the OS I got with it is 64 bit but that varies with each unit they sell so inquire first. These are great people and eager to please.

In the Centronics side, there are 36 pins but in a smaller connector. (I saw Kathleen's answer, 25 pin is on the PC side, the older PCs with a parallel port.)

Neither. it simply makes printers usable on a network by tricking your PC or Mac into thinking that the device is attached to a usb port. Not an elegant solution, lacks meaningful support from the manufacturer, and unfortunately the software is a bit buggy. We basically stopped using the printer until I find time to implement some other solution.

The only ports on printers I am aware of are 25-pin DB25, 36-pin Centronics and 4-pin USB. This cable is a 9-pin Serial to USB adapter which creates a COM port. If you do happen to have a printer with a 9-pin port you would still need printer drivers compatible with Windows 7, which are quite rare with older printers.

I can not answer your question because I do not know very much about different printers

There are several differences in features and paper capacity. Check this website for details: http://thetonerexpert.blogspot.com/2013/03/canons-new-mfp-printers-imageclass.html

Hello. The only thing to do is buy the right one. You have to look closely to the port side of the adapter and the printer. I'm sure you probably noticed the port pins don't match up with the adapter's. It's tricky. Look for a seller with a big enough picture to make sure the slotted side on the adapter matches your printers port.

The difference is probably in the number of pages from the color cartridges. There is only one black cartridge, the TN221BK but there are two different sets of the color cartridges - the TN221 series and the TN225 series. The TN225 series cartridges will print more pages than the equivalent TN221 series cartridges, thus the higher price. I saw a Brother 5-pack that had all TN221 series cartridges for less than the one I bought. A lot depends on what you print, but it is likely that you'll get more pages out of the set with the TN225 color cartridges.
