There are some open source tools available that convert HTML to PDF:

Hi Marc,

Can you please provide an example that used wkhtmltopdf to covert html to pdf.

FYI,

I want to convert html to pdf programmatically.

The wkhtmltopdf website has an example of the command-line usage -- looks fairly simple.

And have a look at our product documentation for $ZF(-100) on how to execute an external program from ObjectScript.

Hi,

a sample:

set command="c:\MyProgDir\wkhtmltopdf.exe --print-media-type --page-size A4 --orientation Landscape --margin-left 5 --margin-top 5 --margin-right 5 --margin-bottom 5 c:\MySourceDir\myHtml.html c:\MyTargetDir\MyPDF.pdf"
set ok=$zf(-100,"",command)

on "html to pdf converter freeware" google gave me 3 270 000 hits.
Why reinventing the wheel.
Place your HTML into a local file and let someone else do the dirty job.
There are enough solutions for a call-out to trigger the conversion.

Use Pupeteer. Follow the third option tutorial and you should be fine.

P.S.: You need NodeJS to run Pupeteer.

Hi Vivek,

We bought a license for CoolUtils (coolutils.com), whch also has command line functionality. There are dozens of different converters with CoolUtils, but you can buy just the one.

We use a batch file for the command line, which will take two parameters, and an "option file" (used by the converter):

"C:\Program Files (x86)\TotalHTMLConverter\HTMLConverter.exe" "%1" "%2" -c pdf -fp -combine -si -pc Normal -ps letter -OptionFile %3

then call the batch file using $zf:

set command=dir_"Converters\html\ConvertHtmlToPDF.BAT" set params(1)=fromHTMLfilename

set params(2)=toPDFfilename

set params(3)=OptionFileName

; NEXT: $ZF(-1) NOT USED BECAUSE ANY PROBLEM WITH THE CONVERTER PROGRAM WOULD CAUSE THIS PROCESS TO HANG UNTIL ETERNITY!!! ; Fire off HTML>PDF Converter program in background (-2 = don't wait) s status=$ZF(-100,"/ASYNC",command,.params)

The OptionFile has PDF codes like:

po=Landscape
PgHead=&b&d &t
PgFoot=&bPage &p of &P&bInsights powered by RevenueHealth Systems (C) 2018

I used the utility's "Command Line Parameters" help file to figure out how to set all the options, and how to use the option file. I wrote a note to myself to "See http://www.verydoc.com/htmlprint-footer-header.html" for use on the pdf codes that are in the option file.

It took a while, and I had to program in a new "language" of PDF options and stuff.

Good luck!
