SCSI in parallel port

Can anyone advise me on attaching a SCSI external drive (SyQuest SyJet 1.5 GB) to a parallel port?  SyQuest sells a cable ("adapter") for this purpose with an integral printer passthru for $100.  However, a computer shop tells me to try a plain SCSI to parallel cable, which costs about $40.  Two questions:

1. Will the plain cable work?

2. If possibly not, could trying it cause damage to the drive and/or computer?

I doubt if the plain cable will work as the cable they are trying to sell you is for a 25pin scsi connector which looks like a parallel. You will not damage your machine by trying so why no give it a go and if it doesn't work take it back and get your money back.

Does anyone have more detail or knowledge on this question?  If I can avoid paying $100 for a cable, I would like to!  The $40 cable had the wrong kind of SCSI plug on it.  Here is a description of the SyQuest cable.

I guess the basic question is whether the thing is just "adapting" the plugs/sockets or if it performs some other function that enables the SyJet SCSI drive to handle  parallel. If something that would work would be available, say at Radio Shack,  or if I could assemble one with various adapter plugs and cables, I would like to know about it -thanks!  

Here is the description:

SyGear SyJet SCSI-to-Parallel Port Converter

                       Description
                       This conversion cable enables you to attach and run an external
                       SCSI SyJet drive through a PC's parallel port. It has a DB25 male
                       connector on one end for connecting to a parallel port, and a 50-pin
                       High Density male SCSI connector to plug into the SyJet drive. The
                       special cable also has a DB25 female parallel port for parallel
                       (printer) pass-through.
