Cannot detect scanner

I have a NEW laptop computer with Windows XP but without a printer port. I installed a parallel to usb device & driver so I could connect the scanner but my computer still does not recognize the scanner. IS there anything I can do to get it to work with the usb port?

There is going to be issues with connecting it in this fashion. The usb adapters are not addressed the same as a real parallel port. This means that the drivers probably do not have a chance at working. The other issue is usb ports on laptops rarely have the power to drive devices larger than a mouse or keyboard. This means that the usb adaptor may not have enough power to function. Try plugging it into a powered usb hub then to the laptop. This may give it enough power to do what you want if the drivers are compatible of course.

Good Luck.

If all else fails goto goodwill and get a usb scanner. I always see stacks of them. Most are the usb type.

I have an old serial printer that works fine, I can not connect it to my new computer via a parallel to usb cable convertor on windows 7!


Hi craig931, First try downloading the latest driver of your printer and your usb converter compatible for windows 7. Second Checked your device manager if your printer and usb to parallel driver properly installed, it should be there. If not yet installed try using different usb port one at a time until the cable have been detected. Third if you see already the printer port force to change it to USB001 or Com1, then try to print. regards,

Am looking at buying a friends 320 scanner, He cant find the booklet or cd 4 it. also doesn't have the parallel cable eather. Can i get this from the company? Also I havw windows xp. will this work on...


First you would need to make sure you have a parallel port on your computer, because if you don't, you would need to get an adapter of some sort for either a p2p or usb port, whichever you prefer. I'm not sure if you can get a parallel cable from the manufacture, but you could probably find it on eBay. With an older scanner and a newer computer, you can probably just plug it in and it will work, but if you need the software, go here: http://www.nodevice.com/driver/320P/get25293.html

Hope this helps!

Usb 1.0 or usb 2,flatbed scanner compatability


Find a USB device, such as a memory-stick, that is "USB 2.0" and connect it to a USB port. If Windows XP pops-up a window ("this device will perform better when connected to a USB 2.0 port"), then you have connected it to a USB 1.1 port.

Yes, you can connect a scanner, if it has a USB connection. Not all laptops have a parallel-port ("old-style" printer) port, but some scanners require a parallel-port.

The computer recognizes the hardware, however scanner is not scanning. Have windows XP. How can I tell if the scanner is broken, there are no lights on it?


your scanner is ok.
But there is communication problem from computer to scanner .
For that
Check your usb cxable and usb port of computer working fine.
Try in another usb port.
If you have other port like parallel port then check it.
Check drivers of scanner are instaled proeprly.
Ig already installed then uninstall it and install again.
Also uninstall all usb drivers then restart the computer then it automatic install usb drivers .
you can uninstall usb drivers from computer with device manager.
Press windows key + Pause break key to see system proeprty then go to hardware then you see device manager then uninstall all usb drivers.

Cable connectivity with my laptop through a "parallel to usb cable". My laptop has no parallel port but only usb ports.


make sure you follow this step :
1. install driver USB to Paralel port (LPT1) before the cable connected to PC
2. After the driver installed, install the cable - and it supposed to be detected
3. the last think u have to do is install the scanner/printer driver

if it is not work, i guess the problem is on the USB to paralel adapter, or the driver not installed correctly

Canon BJC 2000 question-1284 to usb

The software package just doesn't work well with older peripherals that use legacy parallel or serial com ports. Too many sloppy layers.

THE BEST WAY to add an LPT printer port to your laptop is to use a PCMCIA to Parallel adapter card.
The PC Card slot provides access to the laptop's data bus, and the PC Card adapter easily sets up as a native LPT port within almost any OS.

There is no delay, or connection problems as I've seen in so many complaints about USB to Parallel or Legacy Serial adapters. Printing is Instant.

PCMCIA is a mature standard, and works seamlessly with XP and Vista, and almost any other OS.

PARALLEL is the old standard fast data protocol. IEEE 1284 ECP mode up to 1.5 Mbps.
The BJC-80 and the BJC-85 have the same print speed. The BJC-85 just added USB.

INFRARED is ver 1.0 on the BJC-80, and printing is a bit slower at 115.2 kbps. Even the BJC-85 with its higher IRDA transfer rating and a laptop's built-in IR port, the XP print spooler has problems with it, and can hang if printing more than one page, and especially with more than one document. It will not scan.

I use IR for printing single pages only with either the BJC-80 or BJC-85.
USB to IRDA adapters work fine, and are less expensive $5-6 than
PCMCIA to Parallel adapters, $20-25.

I have tested and used several PCMCIA adapters from different manufacturers, and they all work perfectly as a hot-pluggable, instant LPT and/or Legacy Serial port for my laptops.
TIPS:
After installing the PC Card driver, check Device Manager for the LPT port number.
Install the printer manually from the list of printers, and select the proper LPT port.
Most laptops have two PCMCIA slots. If you change slots, the adapter card driver may reinstall, and assign the next available LPT port, LPT2.

To scan with the BJC-80, you must have an LPT port.
The PC Card adapter also allows the use of the IS-12 scanner cartridge within XP or Vista.
Within Vista, set the Canon ISScan software to run in Windows 98 compatibility mode, to allow use of the TWAIN driver.
