Frequently the 25pin plug on a PC is a parallel port, not a serial port. Perhaps it is this you mean.

Kids gave me a printer/scanner Epson model number c171a. Need the cable to it. AN oldie but looks like a pretty nice printer. Can you help??


The cable you need depends on the unit. I am not aware of a C171a model from Epson. I have seen it listed as a version of the RX500. In that case you need a USB cable with A/B male ends.

Otherwise, most printers (from about 1997 on) will use a USB cable. This has two male ends - a square end goes into the printer and a rectangular end that goes to the computer (called A/B). For older printers (there may be multiple ports or just one), you may see a parallel port (the cable has a wide rectangular plug on both sides with 36 pins) or serial port (the cable may have DB9 (9 pin), DB25 (25 pin) or both). Often it is called a RS-232 port. For a parallel port connection, you would need one that is designed for scanners and bi-directional communication (USB to parallel adapters are available to connect this to a new computer but you still need the bi-directional version). Similarly, USB to serial adapters are available.

Generally you can tell what cable you need by looking at the back of the unit where the ports are. (Although some all-in ones have the USB cables in other places - routed through the side of the unit but the plug is near where the ink cartridges go.) Then the size and pin counts for parallel or serial tell you what cable to get. There is usually a symbol indicating the cable type as well near each port. USB cables are usually indicated by a tree like symbol with curved branches.


I hope this helps.

To connect gps to computer wich pins do i connect of nmea cable?


pins 2(-) and 5(+) on a 9 pin serial cable, then you need a usb to serial adapter for input into the computer if you do not have a built in 9 pin serial port on you computer because the usb moves the information faster than the gps signal. gps is roughly 4800 baud, usb is moving so much faster you need a buffer

Trying to connect a lap top to the 450C designjet but don't have the proper connection to hook up


I believe this plotter has both the old centronics and a 25 pin serial connection. Your laptop MAY have a 7 pin serial connection which you can get a 7 pin to 25 pin serial cable. If your laptop does not have a serial port, you MIGHT find a USB to serial adapter cable.

Make sure you are not on Vista or Win 7 operating systems as they likely do NOT have compatible drivers for this plotter.

Zebra 105SE 25 pin serial cable


error can be on the pc.side or the printer's:

check

- if in windows the LPT ports are addressed properly (if u got a many usb ports, then windows adresses these first and skips the older lpt's- same applies when using an external usb-hub/splitter!)

- that there are no dma or irq conflicts
(see device manager)
- if the right driver is installed, if it suits the windows version u are using/has been written for it

- doublecheck printer against another printer
on your pc using same port

- and/or try to connect it to another pc

so u make sure on which side the error ocurs!

least: check the cable itself

Hook Up possible for EPSON Stylus 880 to new computer w/USB ?


There is no conversion cable that you can use with parallel connector since USB transfers data in Serial mode and the parallel cable handles data in Parallel mode.

Sorry.

Want to connect to my computer


What connector/interface does your PC has
9-pin or 25-pin connector

If it has 9-pin connector: use the following:
DB-9 RS-232 Serial Connection
or
DB-25 RS-232 Serial Connection

If it has 25-pin connector: use the following:
DB-25 Serial Connection
or
DB-25 RS-232 Serial Connection

If you are configuring the computer to use an RS-422A serial port, you need a special cable. Contact the computer or printer network manufacturer to see if an RS-422A cable is available. If no cable is available, contact your computer manufacturer for your computer pin assignments and have a cable constructed.

The default configuration for the serial port on the printer is for RS-232C serial communication. To set the printer to use RS-422A serial communication, change the control panel Serial Menu’s SERIAL setting to SERIAL=RS-422.

Epson TM-U325D Serial Printer - No Print Activity


make sure you have the printer added in the printers window of the control panel. Epson Expert
suggests adding the printer as "generic". Mine is USB, so I have to run their COMUSB program.
Right now I am having a problem printing receipts. It seems the text is too wide for the line.
