Intercept data sent to printer & insert into DB

A legacy application (I don’t have the source code for the application) transmits reports to a printer. One of the reports that are sent to the printer needs to be inserted into a database. With VB.NET can I intercept items that are sent to the printer? Can I read what is being sent to the buffer with VB.NET and save to a file? Please let me know if this is possible with VB.NET. Should I be using a memorystream and window services? Please let know if you have any ideas. I could use all the help that I can get. Thanks

How Do I Intercept Data Sent From A Printer Attached To Retail POS In A Store?

Hello,

Please I need help from experts familiar with printer technology, I'm designing a loyalty solution that will capture transactions performed in a retail store, I'd like to fetch the records of the items and amount sent to the printer for receipt printing. Is there a way i can intercept that data and store in a location for later collation?

Appreciate any ideas on this.

Intercepting printer output

How is it possible to intercept data going to the printer. This would allow for example to replace one font with another, or one string with another, and then continue sending the stream of data to the printer (whatever printer was selected by the user).

The changing of the printer output would be independent of the user, and would work on output to any port (parallel) or to a network printer.

Thanks very much for any ideas or code.

printing order intercept with c#

I need to intercept a print order from a program like Core, Photoshop or Word and capture a series of data from it just like the print date, dimensions of impression etc. to save in a database and then release it to print.

How to intercept a print job convert it to plain text and print?

Dear Experts,

I need some advice and tips for a new project i want to start.

I will be working with several bars and restaurants for a loyalty program.

Since all the customers already have a POS Software/Hardware from different vendors, I need to write a program to be able to capture in plain text the final invoice when the POS prints the final receipt.

The process should be something like:

1. The user send the command to the POS software to print the final check.
2. The program will intercept the printing job, and create a plain text file and store it into the local PC.
3. The check is printed automatically.
4. This should be done in silent mode, the user should not notice anything different.

My questions are:

1. Is this possible to do with POS printers like the ESPONS TM family printers?
2. First I want to build this for windows XP to windows 8.
3. Which programming language is more suitable for this task? I can use C# and Delphi.

I will give the max point available!!!

Thanks Experts!

Need to intercept USB data stream going to printer

I have a label printer connected to a PC via standard USB 2.0 A to B cable. What I need in terms of functionality is a USB Y cable that would send the print data stream down both cables simultaneously. I know.... I know... these cables don't exist, and due to the characteristics of the USB com protocol, it's not as simple as splicing in another cable. However, I know there must be a way to create a redundant data stream.

REQUIREMENT: The printer must still generate a label and the 2nd data stream will be routed to a PC and captured for logging purposes and further processing.

Due to security issues, I wont be allowed to touch the computer or printer, therefore whatever solution I use must reside between the PC and Printer.
--------------------------------------------
Intercepting data sent to the printer

That printer uses ESC/POS language.  And, unless the application is selecting a printer's resident font (if available in the printer driver), or it is a text only driver (unlikely), you won't be able to actually read the text and edit it.  Usually, the driver will convert Windows fonts into pixel information (as Abdul mentions), so all that you will get is a graphics bitmap representation of the page being sent to the printer.  If you set your port to print to a file, and open it with a hex editor, you will probably see a several of 0x1B 0x2A commands followed by some data, which is the usual ESC/POS graphics command.  If you are lucky though, the application could be selecting the printer's resident fonts, in which case you should see the text the application wants printed somewhere in the file.

How to Intercept the data that is being sent to an Epson POS printer, from a POS software?

The setup is simple. There is a desktop that has the Point of Sale software on it. It routes all the POS stations through itself and whenever a ticket is needed to be printed, the software sends the info to the printers through Ethernet cables to the printer's IP addresses.

I'm trying to figure out an easy way to capture that data in ASCII essentially and don't even have to modify it.

One of the answers to this question was to check off the box "keep printed documents" and then looking in the spool directory, but that only works with regular printers that are directly connected the computer and for which the computer has the drivers. In my case, the POS software itself has all the drivers I guess and there are no options to keep the data that is being printed.
--------------------------------------------
How to intercept data being sent to a printer?

I'm interfacing with an application that's sending a raw printer file to the default printer. This is the only thing it will do with the data.

I need to get this file somehow so I can store it elsewhere instead. What would be the best way to do this?

The best I've thought of is to write an app that listens to a specific port, and set the default printer to that port.

Would this way work? Is there a better way?

Saving a pending print job as PDF

I printed an important receipt and quit Safari, only to learn the job never printed because we no longer own the network printer the computer was expecting to find. Thus, the only remaining copy of this information is in the print queue.

How do I salvage the information waiting to be printed so I can use it again?

Note: Dragging the enquired item from the non-existent printer's queue to an existent printer's queue will print the item. I would like to know how to save the file waiting to be printed so it can be used again.

Capturing print output as vector format (PDF,SVG,EMF,etc.)

BACKGROUND

  • I am using a commercial application on windows that creates a drawing
  • This application allows only two output options: (1) save as a bitmap file and (2) print to a printer
  • The bitmap is useless for my purposes - I want the vectors
  • Looking at the print output (I sent to the Windows XPS print driver) it seems clear based on the amount of zooming I can do without loss of detail that the underlying vectors are being send to the print driver
  • Once I get the vectors, I will be writing some code to transform them for some other use.

MY QUESTION

  • What are my options for getting the vectors from the print?

OPTIONS I HAVE THOUGHT OF SO FAR

  • Take the bitmap and use a program like VectorMagick to. I have tried this approach. It does not produce the fidelity I seek even when the original bitmap is large. Practically speaking I believe that using any tracing approach will not give me the quality vectors I need.
  • Print to the Adobe PDF driver. This technically works. I have Adobe CS4 so I can print to it save the resulting PDF and then import the PDF into Illustrator and then export as some other vector format. The problem with this approach is money/licensing. I own a personal copy of Adobe CS4 - so this is fine for me. But I need to capture the vectors at work for business purposes - and no I'm not going to install my personal copy of CS4 at work.
  • Is there a "print driver" that captures the print output directly into a vector format? I have seen some commercial ones via Google. If you've used them, I would like to hear about your experience with this technique. I could write my own and in that case do you have links to any existing code that I can start with.

--------------------------------------------
Capture data from printer port and save to file (Excel/PDF)

I have one mainframe application through which we can send command for document printing. As this application is LAN based and it directly connected to printer on LAN, even though I changed default printer as 'PDFCreater' print command goes to printer on LAN. I want to create one application through which i can read data from printer port and save it into soft copy (pdf or excel) as required.

can anyone help me with this??
