Printing barcode labels from CF

[hofar...@houseoffusion.com]

I'm building a membership system where I will need to print barcode labels
(Code128) from a CF app. I've got the barcode creation down (using a
JQuery plugin), but haven't started the label creation piece. I was
thinking of using CSS + cfdocument, but am concerned that PDF's crappy
support of CSS will cause me trouble. Has anyone else done something like
this? What do I need to look out for?

Thanks

Pete

A number of years ago I accomplished a similar need through the utilization of a client side print ocx which allowed the user to select a printer to be used for label printing. Once they selected the printer, I was able to manipulate the required settings and query paper size information that I would pass back to my label designer and return the HTML that I would then send to the printer. It worked beautifully and the clients loved it.

I do not remember the name of the control, but it was a commercial ocx. Our clients did a lot of label printing so installing the ocx was not an issue for them. I do not know how if you are intending for the client to print barcodes or not, but if this will be an administrative function it might be something to consider.

Yay! I'm useful for something. I have much experience with barcodes printing. Part of the system I work on includes creating barcodes for E-Tickets to be used for admission to amusement parks.

A couple resources for you to use: http://cfbarbecue.riaforge.org/. It's a CF wrapper to a Java library that can create images of barcodes. Once you install it into your CF server (copy some files to a directory, restart CF), you can call the component to create a CFIMAGE and it will spit out a PNG or JPG or what ever other format it supported.

If you're planning on creating a PDF, a couple things you'll have to remember: CFIMAGE and CFDOCUMENT uses an HTTP call to generate those files (or something like that). You'll have to either A) edit your host files to accept your domain B) reference the image using "file:\\\". http://www.ravenglass.com/blog/index.cfm/2010/6/9/Including-Images-in-a-PDF-created-in-CFDOCUMENT & http://stackoverflow.com/questions/10637542/coldfusion-cfdocument-creates-a-red-x

It isn't as complicated as it sounds, just a couple gotcha's you have to be prepared for. Hope that helps.

Sorry if I misunderstand the issue. I've used cfbarbecue http://cfbarbecue.riaforge.org/ in a number of apps with no problems.
It simply uses <cfimage> to print the barcode to the screen. I opened that document in a small window and sent it to label printer using JS window.print().
Then using any label printer I have been able to print the barcode perfectly.

Thanks. I think I'm going to try using CSS and print as an HTML file
first, and if I run into issues, I'll go with cfdocument.

Followup, here's what I used to print to an HP m251w. Works great printing
to Avery 5520 3x10 labels. Set margin to 0 when printing from within
Chrome:

<cfsetting showdebugoutput="No" enablecfoutputonly="Yes"><!--- --->
<cfimport taglib="/extensions/custom_tags/" prefix="ct">
<ct:security allow="board,admin"><!--- --->

<cfparam name="url.memberFamilyID" default="0">
<cfquery name="getRecord" datasource="#request.datasource#">
[redacted]
