[SOLVED] USB Parallel Printer Cable Setup

[Rayaz]

Hi all, have been trying to install an HP Laserjet 4000 printer using an USB to Parallel Cable with no success. lsusb outputs Cypress Technologies usb connector. My system is a Compaq Presario Laptop, 1.7 GHz Celeron M, 1.5 Gb RAM, 80 GB HDD. I am running Hardy 8.04, latest kernel. TIA

Anyone?

Hey guys, 75 views and still nothing? Should I post somewhere else?

[Rayaz]

Give it up as a bad job?

If this issue doesn't get sorted out, I guess it'll be back to dear old windows

Ok guys, managed to get it up and running using a cross-over lan cable with a static IP address. Yeaah!

Good to hear Rayaz, my only other suggestion would be to get a PCI to parallel card / get a usb printer (they're cheap anyway).
But I confess, I don't know much about usb -> parallel converters, I only know some usb -> serial stuff.
Glad to hear you got it going anyway

I, too, am using a USB->Parallel adaptor with which to connect a parallel printer, an HP LaserJet 4L. All seems to go fine except for one thing - the system can never actually find a printer device. Just like the original poster of this thread, lsusb outputs Cypress Technologies usb connector for the port to which the adaptor is connected.

Each time a setup program tries to find the printer, nothing can be found.

I'm beginning to think it isn't possible, i.e. that Ubuntu 9.10 isn't capable of seeing a parallel printer 'hidden' behind a USB->Parallel adaptor.

All help, suggestions, or ideas are welcome.
