USB Printing with Windows 7 on MP C300
I have a lovely brand new MP C300. Set-up in the shop and it worked just fine. Hooked it up to a Windows XP PC via USB printer cable, worked great.
Took it to the customer site, they just wanted to hook it up via USB. Plug in the USB cable, Windows 7 Pro 32-bit sees the USB device installs the proper MP C300 PCL5c driver for it, and tells me that it is ready to use. Tell it to print the test page, nothing happens. Open up notepad, tell it to print a page, dialog box pops up about sending the document to the printer, then closes like it does when it successfully sends a document. No document shows up in the printer queue, nothing prints.
Get a laptop running Vista, plug in the same USB cable, Vista recognizes the printer installs the driver for it and prints like a charm.
Four different drivers, numerous re-installs, reboots, plugging and unplugging, and 1.5 hours on the phone with Ricoh Tech Support gives no changes what-so-ever.
It has all the latest firmware.
So, anybody got anything new to try? Have similar problems? Got a sledgehammer I can borrow?
