2023/02/08

VeryPDF PDF to Text OCR SDK for .NET is a cutting-edge OCR software development kit that is designed to help developers create custom OCR solutions. With its powerful features, this product is ideal for use in a variety of development environments, from entry-level OCR software to complete document management platforms.

Building a custom virtual printer driver with VeryPDF Customizable Virtual Driver SDK

2023/02/04

Creating a virtual printer to handle custom print job events

I'm looking to create a .NET virtual printer that I can install on client's machines and have them print to it so that I can do some custom print job events such as:

Parse the printjob for specific keywords and save the print out as PDF to specific folders depending on the keyword,

* OCR the printjob if needed to detect the keywords
* Anyone know of a library or software that can help me achieve this functionality?

Customer
----------------------------

Building a custom virtual printer driver with VeryPDF Virtual Driver SDK

I need a PDF virtual printer driver SDK that could be seamlessly integrated with our own software.

The following is what we are expecting from the virtual printer driver sdk:

On the output we receive EMF or PDF file (PDF is the most desirable)
It could be installed from our setup app (even parameterized msi would do the job)
Custom name for virtual printer
Redirection to another printer
Notification (executing app with parameters or event sent via named pipe) about start (nice to have) and end (must have) of the process
Ability to work without the windows user logged in
Ability to work as a network shared printer (nice to have)
Printer need to be configurable somehow
We need to hide ALL additional printer related software, control panels etc - it would be REALLY nice if our users have no obvious clues that the printer is provided by the third company
Customizable DPI
PDF can have embedded fonts (nice to have)
Text extraction (plain text format - ANSI, Unicode or UTF-8)
PDF Searchable format
Supported OS Windows 2008R2/2012/Vista/7/8/8.1 driver

The printer will be integrated within our own software which will be publicly available to download. Please specify how the pricing would look like for such a solution.

2023/02/012023/02/01

Hi I am evaluating use of the PDF to Text OCR SDK for .net. Can you help answer the following questions?

1) the SDK is a v2.0 and the command line version is at v2.5 with some new features. Will the SDK have the newer functions?
2) is there documentation for the .net sdk and/or are there additional API calls.
3) does the SDK support multi-threading so we can concurrently process more than one file
4) besides the API calls, is there any functional or performance differences with the command line implementation
5) I found some pdf parsing (not OCR) issues with missing white spaces between words - is that a common issue?

I have been happy with the performance of the command line version and hope to be able to integrate the functionality into our product. Thank you.
