The customized development needs of relevant customers:

Dear VeryPDF,

I have the following project requirements for your evaluation. Thank you!

Project Description:
I need to build a unified printer driver for Windows, macOS, and Linux. Users will only need to install one printer driver on their computer, which should ensure correct output on different brands and types of printers, without issues like garbled text, color differences, and with the ability to add watermarks.

The final goal is to print to a physical printer. We have a print job management system where users initiate a job from their computer, which is then handled in the background. After user authentication on the printer, the job is sent from the server to the physical printer.

During this process, we may need to perform additional processing on the user's print file, such as adding watermark information, archiving (viewing printed content), controlling whether the print is black and white or color, single-sided or double-sided, booklet formatting, stapling, hole-punching, and possibly OCR processing.

Can this requirement be implemented or fulfilled?

Specific Functional Requirements:

  1. UI Interface
    • Original Size: A3, A4, A5, B5, etc. (read original document size)
    • Output Size: Same as the original (use the original size for output), A3, A4, A5, B5, custom sizes, etc.
    • Color Choice: Color, black and white
    • Paper Type: Plain paper, thin paper, recycled paper, thick paper 1, thick paper 2, thick paper 3, special paper 1, special paper 2, special paper 3, transparent film

  2. Add watermark to the file (ensure the file size after watermarking does not deviate too much; larger files may affect output efficiency).
  3. User-friendly UI interface with excellent interactive experience.
  4. PDF files generated by the printer driver should display images correctly, without graphic shifts, incorrect fonts, or text size discrepancies.
  5. The final print output on the printer should have excellent quality, with the output effect matching the original, ensuring no image displacement, incorrect fonts, or text size issues.

PDF Printer Driver Requirement Specification:

Requirement Background:
Build a cross-platform printing solution compatible with multiple brands and models of printers.
The platform solution follows a CS architecture model, with server-side support for Windows and Linux (UOS, Kirin, New Support Point, Ubuntu).

The driver architecture must support both PCL and PS type printers (some printers may not support PS, but only PCL).

Can this project be divided into 4 parts:

  1. Before printing, the user can set various print parameters.
  2. Use a PDF virtual printer to capture the user’s print document.
  3. Store the PDF document and set parameters in a cloud database.
  4. Print the PDF from the cloud database, applying the previously set parameters, to a physical printer (which could be either a PCL or PS printer, supporting both).

The printing function needs to support various printer models. Some printers have different features—some support both PCL and PS, others may only support PCL, and some might be GDI printers, such as Canon’s UFRII driver.

Compatibility:
- Windows XP - Windows 11 (desktop operating systems)
- Windows 2003 and above (server operating systems)
- Linux (UOS, Kirin, Ubuntu, New Support Point, etc.)
- macOS X 10.13 and above

Hello,

We understand and can implement all the above requirements, no problem.

This can be achieved. My personal suggestion is that you treat all print jobs as an intermediate format, such as PDF, PS, PCL, or another format. After the user initiates the job from their computer, your system will convert the print document into an intermediate format and store it in your print job management system. Within this system, you can process this intermediate format with various operations, such as adding watermarks, viewing the content, converting to black and white, printing single-sided or double-sided, and even implementing per-page billing, page scaling, nUP, page cutting, etc. After completing these operations, your system can send the intermediate format to the physical printer for final output.

As for how to capture the user’s print content, there are two basic methods:

  1. Create a custom printer driver:
    The user needs to print to this printer for the print job management system to capture the document for further customization.
  2. Use system-level print interception technology:
    The user can print to any printer, and the HookPrinter Layer can intercept the output and send it to the print job management system for further customization. This method does not rely on any specific printer driver.

We have over 10 years of experience in "virtual/physical printer driver" development, and we have implemented both methods.

For example, the docPrint uses the first technology, creating a virtual printer to capture user print output:

The VeryPDF HookPrinter SDK uses the second technology, intercepting all print data sent to printers through the system-level HookPrinter Layer:
