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.

I have 2 HP Officejet 8610s.  One at my office and one at home.  I cannot get it so that I can print or scan from either of these printers at the same time.  If I print at office when I come home and try and print I have to reinstall the software for it to find the home Officejet.  And then when I go back to the office having printed at home I have to reinstall the software to get it to recognize the office Officejet.

My home and office have 2 distinct  IP subnets  ( and

I have an issue with a networked Kyocera CS 8025ci.  The latest KX driver is installed on a Windows Server 2012 machine and the clients connect to that.  Accounting is turned on.  The problem is that when users print PDF's, it gives the error "Invalid Accounting Code" on the copier/printer.  I've dealt with this issue before and was able to resolve it by setting the printer to "print directly to the printer", rather than spooling (thanks to the thread below):

With the new device, that workaround did not work and I spent hours with the copier tech trying to resolve.  We finally resolved by turning off both Bi-directional support and SNMP.  So, it does work now, but I wanted to see if anyone else had experienced this issue and had any other advice or fixes that don't involve disabling those features.
Dear Experts,
Recently, one of my clients requested I look into finding him a good combination of rugged tablet and mobile printer for his workers to use on the road. This is his description:
"They need to connect via cellular, not just wifi.
Print load is small – perhaps 6-15 prints a day – 1 or 2 pages per print… but need to withstand dirt and mild abuse.
Tablet will access internet and use web for application they will be using.
That website may integrate with google maps, and they may use it for navigation, and they may use email app on tablet"

My past experience with rugged tablet is only with Fujitsu, which I do not see anymore, and I want to make sure that I select a combination that will fulfill their needs without being too difficult to connect to Internet, Cellular, etc.  I do see some portable printers with battery, such as
Canon Pixma iP110 or HP OfficeJet 200 Mobile Printer, but I do not have any experience using them.
If you could share some working sample combinations, I would greatly appreciate it.
I have a single server on a site running Windows Server 2012 and it hosts everything.  It’s a DC, file server, Exchange 2010, and print server.  The users use the built in Windows fax on the server with one of their apps.  Any time a user tries to add the shared fax printer they get the following error:

“Error: A policy is in effect on your computer which prevents you from connecting to this print queue.  Please contact your system administrator.”

This doesn’t happen with the other printers that are shared on the server.  It doesn't matter if I navigate to \\SERVERNAME and double click the shared fax or if I try to add it through Devices and Printers, the same error comes up.  If a user profile has already added the shared fax in the past then it works great, but if it gets removed then they get this error trying to add it back.  I tried removing update KB3170455 from multiple client machines along with creating a GPO that has the following:

Computer Configuration > Policies > Windows Settings >Security Settings > Local Policies/User Rights Assignment
      -Load and unload device drivers set to security group Fax Users
Computer Configuration > Policies > Administrative Templates > Printers
      -Allow Print Spooler to accept client connections > Enabled
      -Disallow installation of printers using kernel-mode drivers > Disabled
      -Point and Print Restrictions > Disabled

I have 2 macOS 10.12.5 + HP 2055DN LaserJet + HP OfficeJet Pro 8210 all Ethernet [CAT-5] connected to Apple Airport Extreme.

Ever since I backed up one of the Macs with resident Acronis, a request to print from either Mac returns:

This printer has been paused. Do you want to resume printing?

If you do not want to resume the printing of jobs, you may add this job to the printer for later printing. If you select Resume and the printing of jobs cannot be resumed, this job will automatically be added to the printer.

Cancel / Add to Printer / Resume

The result of all this is NO Printing! Nada, Zilch - nothing. No matter which option I select or how long I wait. Rebooting all except Airport Extreme does not help. Sometimes the 8210 control panel displays ‘Printing’ - it does not.

As some of you may know, I have been trying for some weeks to establish a fixed IP address for this printer.l NO Luck Yet…

When I power up the printer, the IP address is: - before the Acronis backup, I could print from both Macs until the 8210 timed out and I had to reboot the 8210.

As you might expect I am getting desperate…

If it were not that I need the color printer and there is an AC unit in my office window, the 8210 would be a candidate for Defenestration.

A solution would be most welcome !!
Dear Team, we have several Catalyst 500 acting as Access switches for users, printers, Finger prints (FP) and Access points.

Here is a problem: 2 FingerPrints -----------------------90 m---------------------------- A small switch (LinkSys)  ----------20 m----------- Catalyst 500

In Catalyst 500, there are few modes for port operations; such as Switch, Router, Access Point, PC, Printer,... When I configure a port (which connected to a small switch) in Switch mode, I cannot ping those 2 FPs, but when I set that port to Access Point or Router mode, I can ping them.

Besides, it only works for few hours before disconnected (request time out). I have to reboot FPs to ping them again.

Can you please explain?
I have a user who connects to this PC at the office through remote desktop from home. De PC at home is a Windows 10. The PC at the office  a Windows 7 pro connected to a Server 2016 Essentials domain controller.

When he uses the RDP, he wants to use the printer at home, but his printers don't tag along when he makes the RDP. The option to use the printers in the RDP has been set. The printer at home is a Brother hl5450dn.
I am automating the printing of 50+ reports to specific printers based on the report that I will be printing. The specified printer is not currently listed in my printer selection list. This is due to a thin client that upon logging in resets the list to default printers in the area. I want to automate the setup of the network printers I currently have to manually setup every day.
My tech team is having some major issues. I don't want to brush them off as simply VMware's USB problems without digging a little deeper.

- We have a VDI environment using VMware solutions.
- We have Dell thin clients deployed at all locations.
- Our data line for our main location is 100MB fiber.
- Data line at our data center is duel gig fiber lines.
- scanner is an RDM7000 series.
- Vendor is web based and requires the scanner to be USB attached.

The scanner will work for one or two scans but then become unresponsive. The VDI looses communication. We have to restart the VDI instance to get the scanner to work again. Not the VDI thin client but we have to have an admin go into the ESXi and restart the user's instance. Support team believes the lack of full USB support by VMware is causing communication issues over the USB. They are suggestion deploying local desktops for check scanning. This is not an option.

We have a test desktop setup with VM Horizon client. The scanner has no issues. We have tested multiple thin clients from different vendors, all with the same issue. So this has eliminated the Dell thin client.

We are testing the RDM9600i which is a network connected machine. We are trying to setup the machine as a spoofed USB connection on the VDI but that has not yet worked out. Plus the vendor does not support the machine.


We are looking for a robust Virtual PDF printer, with the following features:
1. Create PDF files
2. Combine documents: Say for example we have separate documents that need saving as one PDF, the printer will act as a repository for the printed files, after which we can save to PDF. This is vital, as a lot of freebie pdf printers will print each document to a separate PDF file. Whilst we are aware that there is software to combine PDF files, we want to avoid this step.

Editing features are a plus but non essential:
1. Delete unwanted pages
2. Add watermarks
3. Print on electronic letterheads
4. remove graphics

We are specifically looking for this to be installed on a Remote Desktop server so that it is available for all users. Google has thrown up a lot of very expensive options. Does anyone have anything reasonable they can recommend?

I have an issue print a pdf label to a zebra printer. I can print the file fine using the printdocument class, however the issue is the speed. It takes far too long to print.

So instead my idea was to send a zpl command directly to the printer and see if the performance was improved. To do this I am converting the pdf file to an image file and then trying to send the image using the below code.

 string zplImageData = string.Empty;
                //Make sure no transparency exists. I had some trouble with this. This PNG has a white background
                string filePath = GetLabelTemplateFolderPath() + hu + ".png";
                byte[] binaryData = System.IO.File.ReadAllBytes(filePath);

                foreach (Byte b in binaryData)
                    string hexRep = String.Format("{0:X}", b);
                    if (hexRep.Length == 1)
                        hexRep = "0" + hexRep;
                    zplImageData += hexRep;

                //string hex = BitConverter.ToString(binaryData).Replace("-", string.Empty);

                string zplToSend = "^XA" + "^MNN" + "^LL12000" + "^PW12000" + "~DYE:" + hu + ",P,P," + binaryData.Length + ",," + zplImageData + "^XZ";
                string printImage = "^XA^FO115,50^IME:" + hu + ".PNG^FS^XZ";

                SendStringToPrinter(printername, zplToSend);

                SendStringToPrinter(printername, printImage);

This code prints a small …
I have the occasional issue where I am trying to reinstall a printer for a client via remote and it calls for unplugging the printer from the USB port.  If the client is not there, I have no way to unplug the printer.  Does anyone know of a app or routine that I can simulate/turn off the USB port to trick the software into thinking the printer is not plugged in and then turn the port back on when the software tells you to plug the printer into the USB Port.  Some HP software will not even uninstall the software until you unplug the printer from the USB port.  The majority of the computers are either Windows 7 or Windows 10.

Any ideas would be helpful!
We recently replaced an old HP LaserJet 4015 with an HP LaserJet Pro M26nw in our school office. Now when we try to print anything with the school letterhead the images on either side of the school name print so large that they are unrecognizable. We are printing from Office 2010 and the operating system is Windows 7 Pro. I have already changed the setting within Word to letterhead but that made no fifference. What settings need to be changed to get the letterhead to print properly?

Thank you.

I am trying to print Persian character on my Zebra Z410 label printer. But for some reason it is printing ?????. The ZPL code I am sending to the printer via Zebra Settings Utilies

Printouts from bank (remote sign-on) is in an enormous typeset. What should be printed on half a page needs two.
This happened after a friend used the printer for the scanning of photographs. It must be a setting somewhere she inadvertently set.

Hi experts,

I was looking around the web trying to find an implementation, but to no avail.

What I'm actually interested in is to detect if a Printer has PostScript support enabled.

I have tried POSTSCRIPT_IDENTIFY checking for PASSTHROUGH and POSTSCRIPT_PASSTHROUGH, but that does not work; some printers that have Postscript capabilities are not detected.

I found that the Java PrintService.isDocFlavorSupported works exactly as I want it to, but PrintService is an interface, and I can't find the logic that shows the implementation. I can't use the Java library as the application I'm working on has requirements to be a .NET application.

Does anyone have experience in figuring out how DocFlavor detection works, or better yet how to detect PostScript capability?

EDIT: I realised I was using the wrong printer driver...  was using Samsung Universal Driver instead of Samsung Universal Driver PS. Seems like the POSTSCRIPT_IDENTIFY detection is working as intended. If anyone has any prior experience/issues with this method, please do let me know though!

Best Regards,
Hello All,
I need a scanner where i can scan bulk of my documents one by one. It should take the documents automatically and scan one by one one the bundle is placed in it or on top of it. Could someone suggest me which one will be the good one?

I searched over internet and came across to the below few printers but not sure never used it before. so need some best suggestion so that i can buy it.
HP ScanJet Pro 4500 fn1 Network Scanner
Kodak i2420 Scanner
HP ScanJet Pro 2500 f1 Flatbed Scanner, (L2747A)
I have a MP 5002 that won't scan to email, I receive an error message that states- transfer to server failed scan has been aborted
We have continual problems with paper jamming in the fuser units, and when replaced the fusers last anything from 3 months to 3 days.  Oki state that its because we use compatible toners, however the toner suppliers state this is not the case and it is up to Oki to prove this, however Oki will not respond to me now.  Has anyone else had similar problems with the Oki C711 ?

Please help me i try to factory Reset of my SHARP AR-6023n printer. i have not found options. and please share with us link where i can download driver of same model printer.
Sorry about the many words, but this problem has vexed me for many weeks.

I have HP OfficeJet Pro 8210 which does not maintain IP address - this IP address is assigned at printer powerup. Daily Powerup/Powerdown is usual (not always) in our office.

8210 is Cat-5 connected to Apple Airport. 2 Macs are macOS Sierra 10.12.5 I also have HP LaserJet P2055dn on same network with IP address (?) that is always powered on and available on the local network.

My question is how to assign  permanent IP address to HP 8210 as with the HP2055dn.

Addressing the 8210 from Safari []  returns:

HP OfficeJet Pro 8210
Embedded Web Server

Network Summary

IP Address:
Host Name:HP0B93E3

8210 times out after 15 minutes - ‘try again’ in Wired (802.3) reconnected to IP address until next timeout.

Maybe change timeout from 15 sec. to infinite? (How?).

Having tried unsuccessfully to re-enter the IP address (still times out), maybe enter something like

Assign fixed IP address -
i have a tvs msp 145 plus dot matrix printer. i tried lot but can't find this driver. kindly help me
So our old DesignJet popped up with  a replace yellow printhead message. So of course I replaced all of the printheads and cleaned all the contacts first. The printheads had 2300+ days usage on them.
I still have the error message. I can check the printheads by the menu and see that it recognizes the new printheads. Shows 0 days on it plus their warranty info.
Anyone have any issues like this? I am suspecting either a defective printhead or something else is going wrong with this printer. Probably more likely something else is going wrong.
Thank you.
My OS is win 10 pro 64 bit and I have the above printer, cum scanner and Fax.  I downloaded and installed the latest driver.  The Printer works, but the scanner does not.  And I seem to get the attached error whenever I bootup and I am not sure  whether it is related to my HP device driver.  Hope the experts can please suggest how to fix this.
thank u.

I have 3 new HP printer  connected to Windows 2016 print server with universal drivers.

Printers are rebooting randomly but it seems in the same time (i ping all printers and ping stop at the same time).

I guess its network issue but i cant find the problem.

Thanks for your help
