Printer problem: Couldn't open /dev/usb/lp0


I am using CUPS for my printer configuration. I have "HP PSC 2110 all-in-one" printer. I configured it to use HP PSC 950, foomatic + hpijs (en) model/driver for it as I don't have one specific toh my printer.
When I finish configuring it,it displays below information.

Description: HP Printer
Location: /dev/usb/lp0
Printer State: processing, accepting jobs.
"Unable to open USB port device file "/dev/usb/lp0": No such device"
Device URI: usb:/dev/usb/lp0

I can't understand as to why it can't open /dev/usb/lp0 when it's there with below permission.

[root@RH80 deepika]# ls -al /dev/usb/lp0
crw-rw---- 1 root lp 180, 0 Aug 30 2002 /dev/usb/lp0

Can someone please tell me what is the problem? And I also need to know if I need specific driver for my printer and where can I get it from?

Please help. Any information will be of great help.

Thanks & Regards,

the psc 2110 has a perfect working status::
read here there is docs plus driver
so maybe the wrong model/printer configuration is making this be all messed up

I know this might sound really very stupid but I want to know how can I find if a given printer is a PostScript printer or not. I have HP PSC 2110 all-in-one printer. I have gone through above link but didn't find any way of knowing that.

Please advice.
