Random print jobs showing up in print queue when printing...

Whenever I print something, one or two other random files will show up in the print queue. The printer will not try and print these additional jobs, and it does not prevent another print job from printing, but each time more random files will show up. The print queue will fill up with these additional jobs until they are manually deleted. What a pain. Does anyone have a solution???

These random files can be communication files and are used to interogate the printer about its status. Typically they will be processed by the printer and then vanish from the print queue. So if they are not being processed and you are having to manually remove them then there could be a setting in the printer that needs to be changed or you have to check from an updated driver.
To confirm if it is the printer queue / driver that is checking the status, you can open System Information (Applications > Utilities) and select Printers in the left column. You can then select the printer in the top right pane and see its information in the bottom right pane (or if this is the only printer you have the information will appear in the right pane). You will see an entry called Printer Commands. If it shows something like Report Levels then this confirms that these files you are seeing are for checking the printer status.

C# console app - print job vanishes in Windows 8 regardless of print driver used; works in Windows 7

I have the following which sends a print file to a specific printer. It works perfectly in Windows 7, but not in Windows 8. The print job shows in the print queue until the print job is closed. Then the print job literally vanishes from the print
queue. This issue occurs with all print drivers, including generic text only. Conversely, I can still use the "winspool.drv" DLL directly under Windows 8 and it works. Please advise. Thank you.
Here is my code:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.IO;
using System.Printing;
namespace PrinterLib
public static class PrintToSpooler
public static string SendFileToPrinter(string szPrinterName, string szFileName, string docName)
try
// Create the printer server and print queue objects
//PrintQueue defaultPrintQueue = LocalPrintServer.GetDefaultPrintQueue();
//PrintQueue mypq = new PrintServer().GetPrintQueue(szPrinterName);
//using (var printq = defaultPrintQueue)
using (var printq = new PrintServer().GetPrintQueue(szPrinterName))
using (PrintSystemJobInfo job = printq.AddJob(docName))
using (var memoryStream = new MemoryStream())
FileStream fs = new FileStream(szFileName, FileMode.Open, FileAccess.Read, FileShare.None);
fs.CopyTo(memoryStream);
fs.Close();
Byte[] myByteBuffer = memoryStream.ToArray();
// Write a Byte buffer to the JobStream and close the stream
job.JobStream.Write(myByteBuffer, 0, myByteBuffer.Length);
job.JobStream.Flush();
printq.Commit();
return null;
catch (Exception ex)
return ex.Message;

Hello folks,
I have been facing the same problem until right now. All above suggested methods failed (as it did for Jeff0123) . But after long research on that issue I think I found the reason (but no proper solution yet).
MS Windows 8 and 2012 use a new printer driver generation based on XPS. Which means drivers like "generic text-only" won't work properly depending on the method the data is sent to the printer. In my case the
same way like Jeff0123 tried to access the printers.
See link http://support.microsoft.com/kb/2779300
One solution might be to use API calls. I have also found a site which shows an example project for thermal slip printing. The VB.NET source code there features a wrapper class for all API calls. The functions you find behave pretty similar to the ones of
the posted C# code example of Jeff0123. I did a small test so far and for my needs that works fine.
Although the page is in German you can find the mentioned class by searching for "Public
Class RawPrinter". Beside the comments the class methods are written in English. You find the class here: http://www.vbarchiv.net/tipps/tipp_2375-kassenbon-drucker-mit-vbnet-oder-c-per-esc-pos-befehle-ansprechen.html
Hope that might help for at least a few of you. So long!

Why do graphics and colors that appear on the monitor show up as blank spaces when printed out

Graphics (especially color) on emails and attachments show up as BLANK spaces when printed out.
Also, some color graphics and detail work of those graphics on familiar websites do not show up on my monitor
Both of these situations DO NOT occur on Explorer. With that browser - everything is OK

it may have worked, but gimping my system isn't exactly a solution, more of a band-aid.
its the equivalent of the old
patient says, " its hurts when i do *this* "
doctor replies," well, don't do that "
What do you mean "it may have worked" – did it or did it not?
Anyway it is not a remedy but diagnostics and if it makes a difference it points at the GPU driver as a likely culprit.

Print jobs won't automatically drop from the print queue after printing

I just bought an Envy 7640. When printing multiple documents, the first print job hangs in the queue after it prints, which prevents subsequent jobs from printing. The first job continues to show a status of Printing after it prints the job. I have to manually go into the queue and cancel the finished job before the next job in the queue will print. Having to clear the queue manually each time a print job finishes is not an acceptable fix to the problem. How can I get the printer to automatically delete the print job after it prints like it's supposed to do?

Thank you for your reply. The steps that you sent are for print jobs that you cannot delete from the queue. I also found those instructions earlier, however, it doesn't apply to the problem I'm having with my printer. I don't have a problem deleting print jobs from the queue. As my previous post stated, when I print multiple documents, the first document prints but it stays in the queue with a status of Printing. Because it stays in the queue with the Printing status, it prevents the second and subsequent documents from printing. My problem is that I have to go to the queue after every single job prints and delete it from the queue to allow the next document to print. It's ridiculous to have to delete every job from the queue after it prints. The printer should automatically delete the job after it prints it, and then print the next job in the queue. How can I make the printer delete a job automatically after it prints it?? Can you please give me a resolution to this problem? Thank you.

Network Print Jobs Always Get Stuck in Queue

Hello,
I have, perhaps, the most frustrating problem on the planet. In my home network, I have a HP Color LaserJet 2600n connected to my main PC, with 2 other PC's on the network. All 3 run Windows 7. Printing from my main PC works fine, but if I try to print over the network, the print job always gets stuck in the queue. I can see it stuck in the queue on my main PC, but I can't do anything about it. I can't delete it, nothing. If I restart the spooler, then it magically prints and clears the queue, but it's annoying to have to do that all the time. I've reinstalled the drivers several times to no avail. Tips?

I have a similar problem, I have a directly connected 1300 and a network P3015. The 1300 is connected via USB, the 3015 is connected by RJ45 cable right to the router. Both printers have their print queues get stuck, but only from my HP Pavilion Elite HPE running HP-installed Windows 7. All the other machines in the office can use the 3015 printer perfectly well. One is an older Pavilion using XP-Pro, another is a Dell using XP-Pro and the third is a Lenovo laptop using Windows 7. All our toners are not refills (seems like a stupid suggestion that the toner cartridge could cause a queue to lock up). The problem is definitely between my machine and the HP printers. I have a Brother printer and a couple of Seiko/Epson printers that all work perfectly fine.
Rebooting several times a day is getting old.

Print Jobs Show Complete But Do Not Print

Working with someone that has a MacBook Pro (10.4.11). Were connected to a networked HP-4250 LaserJet. Everyone else can print, when he shows his jobs have completed, but they do not actually print.
I've tried all the variants of Bonjour, IPP, HP JetDirect (deleting each time with multiple restarts), but we still can't get any print outs.
I can also ping the printer and actually log into the setup pages of the printer in Safari.
Recent changes that I'm guessing have something to do with it is that he recently removed HP Director (for All-In-Ones), but I still found some fragments files and folders that I deleted.
He also installed the new scan software for his new Brother's printer. Similar to the HP AIO software. But before I remove that software I'd like to make sure there isn't some other known issue going on. I'm pretty sure I've actually seen this before, but no clue on what the fix was.

Are the others on the network all PCs? Is it possible that the printer's "personality" is set to PCL? That would mean PCs could print, but not Macs (with the preinstalled postscript driver). Fix - set to Auto.
Also try Reset Printing System, then Add the printer again.

How to keep file name in print queue when printing crystal report

We are using VB .Net 2003 + Crystal Report 2008 SP2 up to Fix Pack 2.6
When the VB program spools crystal report files to print queue, the print queue only shows "Crystal Report" for each document. How to keep the original file name? In the past when we were using Crystal Report 11, the original file name can be shown in the print queue.
Please help because it's so important for operation to see which report is failed in printing when reports are printed in batch.
Thanks

Hello,
Set the PrintOption.JobTitle value for the print job. Here's C# code on how to:
               System.Drawing.Printing.PrintDocument pDoc = new System.Drawing.Printing.PrintDocument();
            CrystalDecisions.ReportAppServer.Controllers.PrintReportOptions rasPROpts = new CrystalDecisions.ReportAppServer.Controllers.PrintReportOptionsClass();
            CrystalDecisions.ReportAppServer.ReportDefModel.PrintOptions newOpts = new PrintOptionsClass();
               pDoc.PrinterSettings.PrinterName = cboCurrentPrinters.Text;
               rasPROpts.PrinterName = cboCurrentPrinters.Text;
               rasPROpts.PaperSize = (CrPaperSizeEnum)
                    pDoc.PrinterSettings.PaperSizes[cboCurrentPaperSizes.SelectedIndex].Kind;
            // this sets the name of the print job
            rasPROpts.JobTitle = "MYPrintJob";
               rptClientDoc.PrintOutputController.PrintReport(rasPROpts);
               MessageBox.Show("Printing report.", "RAS", MessageBoxButtons.OK,MessageBoxIcon.Information );
Thank you

HP210a print jobs fail over wireless, but can still print Test Diagnostic page over network

Help! I cannot print over the wireless network anymore. When I try, the print job queues up and I get "Error - Printer" message. I can print the Test Diagnostic page just fine over the network. I can also print fine when connecting via USB port. I have the latest firmware. Any ideas?

Hi HP_210a_user,
Thank you for visiting the HP Support Forums and Welcome. I have read your thread on your HP 210a printer and not printing over wireless. HP Print and Scan Doctor.

Print job will not delete, which halts other print jobs

Maddening issue with some print jobs sticking in print que, then failing to delete when attempting to clear que, which halts any print jobs that follow. Que shows "deleting" but in reality it does not delete. I have tried to go into spooler system and it seems to work when I hit "Stop" then "Start," but do NOT want to have to do this every time. thx for any help.

On order to clear the Spool, the easiest way is to turn off your printer,
Reboot your PC and then cancel all the documents from the Printers screen.
After the documents has been removed, turn the printer back on.
As the issue ocours more often, please let me know your printer model, how it is connected to your PC and your operating system version, it will help to better understand any possible cause.

6500A Plus print jobs sit in tray, and do not print for extended periods

Printer is connected to two computers wireless and has been working fine. Recently began just sitting there after you click on print. Icon comes up in tray, but printer does not start print job. Often get pop-up message that says print job failed, after it finally prints the job. We sometimes have to wait several minutes for it to begin printing.

Let's set a static IP address for the printer:
- Print a Network Config Page from the front of the printer. Note the printer's IP address.
- Type that IP address into a browser to reveal the printer's internal settings.
- Choose the Networking tab, then Wireless along the left side, then the IPv4 tab.
- On this screen you want to set a Manual IP. You need to set an IP address outside the range that the router automatically sets (called the DHCP range). If you do not know the range, change the last set of numbers (those after the last '.') to 250
- Use 255.255.255.0 for the subnet (unless you know it is different, if so, use that)
- Enter your router's IP (on the Network Config Page) for the gateway.
- Enter 8.8.8.8 for the first DNS and 8.8.4.4 for the second DNS.
- Click 'Apply'.
Now, shut down the router and printer, start the router, wait, then start the printer.
After this you may need to redo 'Add a Printer' using the new IP address.

Print jobs keep starting and then error in print que

I have a HP Photosmart 100D series printer. The print jobs keep freezing up in the que. The jobs start and then after a page or two the error message appears when checking the status.
I uninstalled the printer and reinstalled
I have download new drivers
I have run the "HP Print Doctor" it gives a message to save work, close and programs and restart the PC and then restart the ulitity. I have done this and still get the message that it cannot fix the que error.
What do you suggest as a solution to this frustrating problem?
I have Windows 7 Professional OS

Hmm. I have an HP printer that's behaved fine, but I've moved it to my iBook (running Tiger) so I can print wirelessly.
It may be an issue with the driver or the software. I'm guessing the software was written for the PPC machines, and that might be causing the problem.
The way I've checked this is to open up "Activity Monitor" (Applications>Utilities) and find the processes related to your HP printer (usually begin with "hp") under kind what's shown?
You might want to look into the CUPS idea presented earlier as it may give you better results.

When printing, my preview is correct, but the printed document shows only the center of the printed document

When printing from my MacBook Air, Pages shows the correct preview, but the printed document is only a column taken out of the center of the printed page. What's going on?

I should add that when I e-mail this document to myself and print it directky from the iMac, it prints fine.

EPrint sending print jobs in A4 format to US-based printer

When I send a print job via ePrint from my European based virtual desktop to my local US based Officejet 8600 printer, the first page will print with the correct margins but every other page afterwards prints with no top margin. From the looks of it, it is trying to print as it was the longer A4 paper format instead of US Letter format.
I will add this happens with using the duplex print option. Any ideas?

I would need some more information in order to help out. Does this same error occur when you send a print job locally? Locally being defined in this situation as the computer and Printer involved in the ePrint Job being in the United States. Also, have you checked the ePrint settings at ePrint Center to make sure that the paper selected on the printer is set to US letter?

How to show masked links in PDF when printing?

Hello
Ive got a PDF where some hyperlinks are masked behind certain words. For digital use of this document this is fine. However when printing I would like to have the full link to be printed (eg as a comment or on top of the word which contains the link). Is there a possibility to do this with Acrobat?

My Officejet Pro 8000 wireless printer prints to only 4x5" on 8x11 sheet when printing mult pages

My Officejet Pro 8000 wireless prints to only 4x5 inches on the 8x11 sheet when I try to print multiple pages per sheet from an Adobe file. The print preview shows the paper dimensions to be 8x11, and the four Adobe pages are properly scaled to fill the 8x11 printed sheet, yet when printing, all the printing is condensed to the upper left quarter of the sheet.

What did it? I was still trying to figure it out
