some kind of screwed up printer
I sold my old celeron 466 computer to a couple who now need me to put
in an interface card, or a port, so they can connect their printer. They weren't specific as to the model, but it's a Panasonic all-in-one with fax, apparently. The problem is that I don't really have a clue what they're talking about. Their old computer was just that. OLD. He brought me the cable and it looks like a 25pin parallel cable, but it's got both male and a female end, meaning, the ends fit into one another, unlike a standard printer cable with the end that locks in and the end with pins. So I have to put in a port that will accomodate this. I do have a port that will fit it, I don't know if it's the right kind or not, or where to connect it. It's got a 25 pin port, male, and a 9 pin ribbon attatched. Do I just stick this onto com2 and off I go or not? Also, I have a cable with parallel symbols on it, but goes from 25 pin to a 9 pin serial connection. Would this work? |

There are a number of similar looking 25 pin cables.
The most common is a serial cable, which is what is also used for an external dial up style modem. There is a very similar looking external cable (also can be 25 pins, or more) which is called SCSI. This is a faster interface capable of handling about 8 devices in a daisy chain. Typically, SCSI is used for fast devices like scanners, modems, and drives. A number of older printer products used serial interfaces. It is actually faster than the earlier parallel ports used for most printers. Yes, serial ports are called COM ports and today most use only nine pin ribbon cables to connect to the MainBoard. Be aware that there were a few odd serial ports on quite old computers that had odd wiring and voltages, and which could cause damage to the computer and or printer unit is misinterfaced. This is unlikely a problem with anything as new as a Celeron computer, however. You may need access to the printer instruction manual to work out the settings for the COM port, IRQ, etc. Art Alexander wrote: I sold my old celeron 466 computer to a couple who now need me to put in an interface card, or a port, so they can connect their printer.

My 1988 HP Peripherals Configuration Guide has literally 19 different 25 pin to 25 pin RS-232 cables with various wiring combinations. The OP will probably need to do a little more work to find out just what interface the old printer really uses and then find a proper cable. Regards, Bob Headrick, not speaking for my employer HP |

Hi Bob,
Thanks for the heads up on this. Yeah, the good old days when every manufacturer came up with its own "best for us" solution. I knew there were a number of older configurations/wiring plans but I never realized there could be 19 of them. Yike! I'm amazed anyone kept them straight... (I did blow up an Amiga power supply and a chip on a HP Laserjet 1 mainboard on one "experiment" with a 25 pin cable years ago.
