Printers and Scanners





A printer is a peripheral which makes a persistent human readable representation of graphics or text on paper or similar physical media. Traditional printers are being used more for special purposes, like printing photographs or artwork, and are no longer a must-have peripheral; 3D printing has become an area of intense interest, allowing the creation of physical objects. An image scanner is a device that optically scans images, printed text, handwriting, or an object, and converts it to a digital image. Hand-held scanners, where the device is moved by hand, have evolved from text scanning "wands" to 3D scanners used for industrial design, reverse engineering, test and measurement, orthotics, gaming and other applications.

So I am working at the local Hospital and there is a printer,

Xerox WorkCentre 4260

System Software Version:
Main Controller:
Network Controller:      4.02.01
IP Core Software Version      6.6.3.P
DADF :      1.04
PCL5E Version:      PCL5e 6.18.10 12-06-2012
PCLXL Version:      PCL6 05-15-2012

PDF Version:      PDF V1.00.80 04-20-2009
TIFF Version:      TIFF 0.91.00 10-07-2008

and when a User is printing with Color set ON
if one - two sheet(s) are printed out then it will get color.
If you try to print more that that then some will come in color the rest are all B/W

EX: This staff member prints off the scheduling for all of the hospital departments, its in an excel sheet with some cells are color coded for time off/vacation/dept/etc...

some of the cells are "gray" as if monotone was on, when it should clearly be in color.

The driver on the Print Server:


"Xerox Global Print Driver PCL6"

"Xerox GPD PCL6 V4.1.585.13.0"

the attected user is using a Windows 7 Entiprise 32Bit
We recently renewed the root CA certificate to extend the validation period.  Our Servers and some of the PCs are  still using their  old certificate.
Does this old certificate chain to old root CA for trust or new root CA?
I am thinking if installing the new root CA to our printers, but I am concerned that printers might not work since the authentication servers are using old cert linked to old CA root cert.
You help would be appreciated.

I am using Access 2013 with Windows 8.1 and a Zebra desktop label printer Model 450 and model 505.
My printers are attached to my desktop on USB001 and USB003.
I have a label file that I have downloaded from FedEx. It is in ZPLII (ZPL2 is what FedEx calls it) format and I use the Extension .ZPL
The file is correct. I can go to and view the label to ensure it is correctly formatted and looks correct.
PROBLEM:  I cannot get the label to print in code. I have tried DOS using NET USE and redirecting my USBs to LPTs. I have tried using the network name after sharing the printer.
I have tried using copy and copy/b (for binary).  I know this must be just a few lines of code, but after hours and hours, I still can't get it to work.
If there was a desktop viewer for ZPL files, I could shell execute and run that program with a command line parameter, but no desktop viewer exist.
I have put just some of my trial code below, but nothing works.  Please help. Thank you.

'Open "USB001" For Output As #1
'Open "LPT1:" For Output As #1

Dear Experts,

We have some problems with RDS and default printer settings.
My first thought was the checkbox "Redirected Printers" in the RDP icon.
But even when i disabled this, users get a random printer assigned as their default.
Most of the time its a complete other printer. or the PDF writer.
I tried several group policy settings like.

Do not set default client printer to be default printer in a session

Still it jumps everytime.
Problem is. users need to redirect printers and some users dont need redirected printers.
And they all want their own default printer obviously.

Any suggestions? where to start?
I want to print labels on my Dymo Label Writer 450 Turbo using a powershell script.
The neccessary dll's with the Dymo Framework are loaded.
But i keep getting an error message when i try to print.

See my script below:

[reflection.assembly]::LoadFile(‘C:\Program Files (x86)\DYMO\DYMO Label Software\Framework\DYMO.Label.Framework.dll’)
[reflection.assembly]::LoadFile(‘C:\Program Files (x86)\DYMO\DYMO Label Software\Framework\DYMO.Common.dll’)

$label = [Dymo.label.framework.label]::open("C:\Scripts\Dymo.label")
$label.SetObjectText("Name", "John Doe")
$label.SetObjectText("Phone", "0123456789")
$label.SetObjectText("Pin", "12345")
$label.Print("Dymo LabelWriter 450 Turbo")

The error message:

I have an Epson Workforce DS-560 scanner with ADF.  It uses the Epson Scan software on my laptop and connects to the scanner via my WLAN.

I have recently purchased an Epson Workforce ES-300W portable scanner and plan to use it via USB connection to the same laptop.  Will this cause any issues trying to use both scanners on the same laptop??  Do they both use the same Epson Scan software?

I am having printing issues when printing a document or test print to local printer or network printer.  I am getting an access denied.
I have look at other posts but none seem to answer my question.
OS - Windows 7 Pro 64bit
Does not matter who I login as - domain user, local account, admin account all get the same error.
I have deleted all printers, deleted all printer software from programs and deleted printer form print management.
Re-installed the local printer (USB) first from fresh download, updated the firmware on the printer  with no issues.  Once I attempt a test print or print from program get the same issues.  I cannot print to a file using Adobe print either.
I have this Xerox AltaLink C8030 that work with network address book for scanning to email. LDAP was configured to point to our Domain Controller. Then one day it stopped working. The message it first had was "LDAP Database mapping error" once I pointed the LDAP to our other domain controller the error message changed to "Cannot determin if LDAP is avaliable" There is another same model Xerox at a different location so I ensured that the two LDAP configurations are identical with the only difference is the domain controller address is different.
I haven't used my printer for some time so the cartridges had dried up. I was advised by Brother printer support to soak the black cartridge in warm water for a few minutes which I did. hat time it worked but when I started with to work with it The other colors are fine but the black won't print at all, not a glimmer. what should i do? please give me some solution.
Windows Server 2012R2

XPS Document writer was removed from the 'Devices and Printers'

While troubleshooting the Feature was also disabled using: Dism /online /Disable-Feature /FeatureName:Printing-XPSServices-Features

I am now unable to 'Enable' the feature. "DISM failed. No operation was performed." (log is attached.)

Step 1. I'd like to get the Feature enabled.
Step 2. I'd like to get the XPS Document writer back to the 'Devices and Printers'

I have scoured about 20 blogs already; everything on this site, Quickbook links, scf scans, Sharing other XPS printers, deleting drivers, copying drivers, windows updates, add/remove Office365, DISM scans.
i have installed several xerox printers in office on various floors  and they have 802.1x wireless authentication.

what is happening is the sessions are being kept open continuously  even users have finished printing.

we have citrix environment and sessions are basically being kept open from citrix server to print server

basically new copiers appear to stop communicating.  We resolve the issue by backing out the 802.1x config, reboot, and re-authenticate the copier.   We are seeing in the logs that all of the Citrix servers are continuously sending 80 and 443 traffic to all of the copiers.  We are also seeing a great deal of these connections remaining open.  we noted that on a normal day we see roughly 2000 open connections at any given time on our internal firewall.  today we saw over 9,000 open connections, and it was causing management performance issues.  I believe it’s possible that as these open connections accrue, the copier is basically DOS’d and stops communicating

even disabling  the 802 .1x is not helping in this, connections remain open

any idea what could be the cause.
We need to install several printers which are shared out from a Windows Server, on to around 30 Mac devices.

Does anyone know a quicker way of doing this rather than installing the driver on each machine, and installing manually with the IP addresses?

Most are on Sierra, some on Yosemite. The server is running Windows 2016.

On the windows PC's we can obviously just browse to the server and then install by double clicking the icons.

Any more info needed just let me know.
I'm trying to print to a specific printer tray using Google Cloud Print. I'm using the service interface ( encapsulated with C# code ( My impression is that if I can find a listing of trays from the printer capabilities, I should be able to create a ticket to specify the tray. But, I cannot find an example of how to do this.
I came across the following article
We have a very large deployment of VDI VMware Horizon and we use AutoConnect Location-based Printing for VMware View.
We do use XenApp platinum and we are considering to consolidate with Citrix XenDesktop Platinum and consolidate replacing VMware Horizon.

The AutoConnect Location-based Printing for VMware View group policy setting is a name translation table. You use each row in the table to identify a specific printer and define a set of translation rules for that printer. The translation rules determine whether the printer is mapped to the VMware View desktop for a particular client.

When a user connects to a VMware View desktop, View Manager compares the client system to the translation rules associated with each printer in the table. If the client system meets all of the translation rules set for a printer, or if a printer has no associated translation rules, View Manager maps the printer to the VMware View desktop during the user’s session.

With XenDesktop is there a similar feature to accomplish the same or similar functionality?
Hi Experts,
I would like to track the number of pages printed via a printer.
Ther are multiple printers installed, including pdf printer.
I need to get the number of successfully printed pages (number of copy / number of pages) from a specific printer.
Documents are printed by Fastreport . Have you any delphi example, how to realize this?
Thanks in advance, Tom

HP Printers Tray configuration

I would like to know how to configure printing for Specifc Trays, for instance we have printers that have Manual Feed, and other Trays (Drawers). in this case how do you configure the printer to print from Tray 2 instead from Manual feed, or from another tray.

Thank you
some users are not getting their default printer option.
From the GPO side… Currently all printers are in the ‘Citrix XenDesktop Mapped Drives and Application Shortcuts Policy’
If group policy is configured to assign printers it will, regardless of what the Citrix policy is configured to do.  Citrix Policies are processed before AD Group policy, if there is a conflict I would expect AD Group Policy to process it’s setting based on it running last.

I have an Access 2013 database, When printing a report using print preview, we normally right click on the report and choose "Send to Mail Recipient". We then get prompted for what format we want the report to be attached as. Normally we select pdf. At this point it opens the email  application (Office 365) We can then address the email and add a subject and email message. We have about 20 users that have this ability.

1 user has now started having a problem. Instead of being presented with the selection for the attachment format we get this message: [Database Name]: Database can't open the mail session.

The other users can still attach the report as a PDF and send it with their email client.

Does anyone have any idea as to what is happening?

Thank you for your help.
I have had two HP Monochrome LaserJet printers in the last week do the exact same thing. The print gets noticeably lighter as it goes from left to right. The customer said that they replaced the toner twice. Didn't help. I replaced the fuser in one. It didn't help. Someone must know. What is the fix?

   One was a M401DNE. The other was a 252DW. Now to badmouth HP a little. Both of these printers are just about a year and a half old. Both to very, very little printing. You had to take the entire printer apart just to replace the fuser. Not worth the time or the fuser. So it looks like HP is putting out some crap that lasts a little over a year and are made so you can't fix them. You have to throw them away and buy new. Guess what HP? Time to try a different manufacturer.........
Possibly a stupid question. How do you open the toner door? I phoned our maintenance company and they mentioned that you have to wait for the toner to run out and you get an on screen display.

Must be a manual way to open the door?

Best regards,

Hello friends... it's me again... Tim Wells with yet another weird issue.  

So, I have a client who is using a Lenovo laptop with Windows 10 Home.  They have 3 network printers in the office.  5 End users.  The client came in on Friday and called and said she couldn't print.  Sure enough she can't see any printers.  Also, she now can't see her printers at home either.  Everyone else is still working normally.

I can ping the network printers.
I can browse to the GUI of all printers via the web brower.

The printers are still there under Devices and Printers but once I removed them Windows won't find them again.  These are stand alone network printers not connected to any other computers.

This is a new one for me.
