  • 1. Random printer timeout after upgrading to XP
    After updating to XP Pro from 2K Pro, I get random printer disconnects from the local printer. The jobs sit in the printer queue with the "error" flag. After I reboot the computer, the jobs print. This never happened in 2K. Is there some new printer setting I need to know about in XP? I have to reboot every day. Just as background, this is an HP R80 connected by a parallel port to a Dell dimension desktop. I disabled all power settings. Thanks.
  • 2. WIA Page Sizes
    We are using the WIA Twain Scanner Module to acquire images. It gives a number of default page choices but NOT a custom size choice. Is this a function of windows or the drivers? Is there a work around to add a custom page size to the WIA module IS THERE A WAY TO ADD OTHER PAGER SIZES? It appears that the registry for this driver list page sizes in [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Print\Providers\LanMan Print Services\Servers\MS-BO3\Forms] With the values (I THINK) 2,3,4,defing the height and 7,8,9 width (and repeated later in the string "Letter"=hex:5c,4b,03,00,68,43,04,00,00,00,00,00,00,00,00,00,5c,4b,03,00,68,43, 04,00,01,00,00,00,01,00,00,00 How do i convert these into inches to make new page sizes It is for a brothers 8440 printer
  • 3. Cannot Ping or Connect to Printer from Only One System.
    Windows 2003 Server, Windows XP. I have a very peculiar problem. All the systems in my network, except two, can access (ping) two of my network printers. I have a new Dell server and my desktop station that cannot ping these two printers. The server and desktop can ping other addresses and printers, just not these two. It is not the switch I am plugged into, as I have tried my laptop on the same ports and can ping everything. What might be causing this problem of two systems not being able to ping just two addresses? P.S. I ran into this problem as I was trying to connect my network printers to my new server. Two of my four printers connected just fine, but two did not. That is when I tried the ping and found it did not work for the two printers. Help!
  • 4. System cannot 'find' Print Spooler Service
    I'm not sure how it happened, but my printing abilities stopped suddenly. I tried uninstalling and reinstalling my HP psc750 software and drivers but the installation keeps failing to complete. Further research shows me that the Print Spooler is stopped in the Computer Management/Service console. When I attempt to start the print spooler service, the following error message pops up: "Could not start the Print Spooler service on Local Computer. Error 2: The system cannot find the file specified." Services shows the spoolsv.exe file at: C:\Windows\System32\spoolsv.exe My Norton AntiVirus reports that the file is clean, however I keep getting the message that the file cannot be found While I'd like to know just where my Print Spooler file has gone, I REALLY would like to know how to find/repair/reinstall the missing file(s) so I am able to print again. Data: Using XP Home w/SP1 and SP2 installed. Any/all help will most Joyfully be accepted (and would get my wife off my back as she REALLY needs to print some important documents!!) Tim
  • 5. Panasonic KX-P1180 printing problems
    The self testing on the printer tests ok. It will print out a test page when I set up the printer ok. XP did not recognize the printer to set it up automatically and I had to install it manually. I had one page print properly from Corel. After that, it just prints a bunch of charachters and it seems to load thebuffer in the printer up with garbage. Any ideas of where the problem is and how to fix it?

USB001 Virtual printer port vs USB002 Local port vs USB003 Virtual printer port ????

Postby BobLeavitt » Sat, 25 Sep 2004 08:24:47 GMT

I have an hp1012 on USB001 and an Epson Stylus Photo 870 on USB003, both of
which are described as virtual printer ports in the printer's Properties.
Both printers print work fine.  I also see an unused USB002 described as
"Local port".  (Don't ask me how I ended up with this arrangement - I can't
really tell you.)

What is the difference between a USB local port and a USB virtual printer
port?  Should the printers be assigned to virtual printer ports?

I am trying to gain some understanding of what is going on because of a
related problem, and that is that my scanning software (Microtek ScanWizard)
tells me that no printer drivers are installed, so I cannot use the copy
function.  Nobody else to be complaining about this problem.  I am running
WinXP SP1 on a plain ol' Dell 4500.

Any guesses as to what the scanning software might be looking at to
determine whether printer drivers are installed?  I have uninstalled and
reinstalled the scanner and printers and related software so many time that
I have lost count.  I am using the latest versions of scanner and printer
software/drivers.

Sure will appreciate any help.

This might get a bit confusing.
A virtual port is a port that is setup as a link in software to what 
ultimately & usually is a physical (local) port.
The virtual port "virtual0001" might or might not connect to USB Port 1 
(001)
It gets interesting when you swap the printers and connect them to different 
physical USB ports.
To confuse things further, just add a powered hub and connect both printers 
to the same USB port via the hub.
After checking  the printer port properties, etc.for each variation, apply 
finger to lower lip, and make appropriate blubbering sounds. Don't be 
suprised to find different and often confusing nomenclature used by 
different printer drivers.

Things can and have been worse! We used to be forced to write our own 
printer drivers in the early days of CPM, Apple dos, MSdos, and dot matrix 
printers.
Finally, Microsoft was kind enough to supply a sort of universal graphics 
driver included with DOS that accepted a data file describing the 
characteristics of a graphics and /or color printer.

1.Server printers vs local printers to tcpip ports

Hi Folks,

Could someone help me with the pros and cons of setting up network
printers with standard \\server\printer  like settings vs. creating a
batch file that adds all our network printers on each workstation as
local printers printing to separate tcpip ports ?

All the tcpip ports are hardcoded, the printers are somewhat generic
so drivers do not change (HP 4000's), and the ram amounts are the same
on all printers.

Right now my printers are distributed by GPO but I find that
periodically workstations have problems with GPO's and when that
happens ... we loose printers as well.  I was considering just
hardcoded all the printers as local via a batch file.  But I am unsure
if I should expect in a shared environment, wither the print jobs will
queue correctly ? Will print jobs collide ? Will we get more printer
errors ?

Any ideas are greatly appreciated.

2.standard tcp/ip printer port vs lpr ports

is anyone able to enumerate what i suspect is a subtle difference between
the printer port types - LPR ports / standard tcpip printer ports (which is
new to Windows 2000) ??

further - it seems that a standard tcpip printer port can have a
configuration of LPR - is there any way in which this is different to an LPR
port. ??

my spin is that it relates only to the tcpip communication between the print
server and the network attached print device.

are there any other functional / performance related differences. ??

3.Access parallel port via Virtual printer port for USB

Can you help me ?


4.Printer sharing problem (virtual printer port for usb)

I have a laser printer with only a USB interface, that is being shared only
with one other computer in the same office. The printer works fine from the
print server, however when the other computer prints it often freezes.

I've tested the scenerio in a completely different office with two
completely different computers but same printer and still same problem.

I've heard there is an issue with sharing printers using the virtual printer
port for usb. Anyone know anything about this?


5.USB-printer, informations about virtual printer ports?

Hello,
I hope, You can help me:
I want to use two or more printers on my notebook connected by USB. The
printers are connected on the same USB-port, e.g. a canon bj 30 for
outside of the office and a kyocera fs 1010 for use in the office. If
the Kyocera will be installed first, PnP assign it to USB001. But if I
install the BJ30 afterwards, PnP also assign it to USB001 and the
Kyocera will no longer work on this virtual port, because PnP creates
USB002 for the fs1010. Then I have to delete the Kyocera or change its
configuration manually to USB002.

In the registry, there are no entrys in
HKLM\CurrentControlset\Enum\USBPRINT for the BJ30.

Can anybody help me? Where can I find further informations on this
topic (I browsed the MSDN, the platform SDK, DDK and couldn find
anythin useful...)?
Is there any possibility to control this behaviour or to assign the
ports to the printer before the printers are connected to the notebook?

Thanks in advance and sorry for my humble english...
