Problem Connecting to USB Printer
 

I have just installed FC3 and am current with all updates. I cannot get my HP OfficeJet G55 multifunction printer working on this system. It works under Win98, but FC2 didn't even recognize it as being connected.

So, I can now see the printer in USBVIEW!

I have the printer configured with a print queue through CUPS that names the device it is connected to as
/dev/usb/lp0 Hewlett-Packard OfficeJet G55

When I issue a ptal-init setup command I get the following:

When I use the ptal-hp mlc:usb:OfficeJet_G55 device command I get:

ptal-hp: Unable to communicate with device "mlc:usb:OfficeJet_G55"!

Syntax: ptal-hp [<devname>] <command> [-help] [<params>...]
Where <devname> may be one of:
mlc:usb:OfficeJet_G55
Valid commands:
device

It seems like the machine is schizophrenic, knowing that the device is there, being able to, on occasion, connect to it, but not being able to communicate with it on a regular basis.

Questions:
1. Am I missing something here? Is there something else I should be doing?
2. Does the power management mode of the printer make a difference in whether it responds to commands from the computer? (Doesn't work that way under Win98, but who knows?)
3. What do I need to do in order to use this printer under Linux FC3 as a printer and a scanner (I know there is more to be done for scanning, but just trying to get the printing going first)?

Thanks for any help ... Dana
