I have a winforms vb.net application that uses Crystal reports to print labels to a dymo twin turbo printer. The only thing I cannot figure is how to select either the left or right hand spool in code.
Has anyone come across a way to do this please?
I have downloaded the dymo sdk but this is an awful product, the code in their samples does not run and it isn't clear what references if any I need to add to the project.
Appreciate any pointers.

Hello Respected Everyone,
I'm a Beginner level programmer having working knowledge of vb.net. Currently I'm working on a program in VB.NET, which will extract labels from an HPGL file and print them on Thermal Printer. I've successfully read and extracted the Label Values from Label Command. Now I'm trying to create an HPGL viewer in my Program. I've searched the internet for any Library or sample program which can guide me through but haven't found any reasonable answer. Please Guide me how can I view an HPGL File in a vb.net program.
I'll provide more information if needed.
Thank You in advance...
I have created a basic RDLC report in Visual Studio 2010. In the report designer it looks fine, and when I use the report viewer to view the report it also looks fine. However, once I send the report to a printer, there seems to be an issue with the kerning or tracking, such that there are no spaces between characters, and all the letters are somewhat wider than they should be. Has anyone come across this before and if so, do you know how to fix it?
I have an application developed with Vb.Net 2003 and using Crystal Reports 11 used to preview many statistical reports.
I always preview any report successfully, but when exporting some of the reports (not all) into PDF using the built-in export functionality in the report viewer control, the application freezes forever.
So, I need to know if there is any report object (textobject, Picture, Chart, line, box, etc..) that might not be able to be exported into PDF, and I think this type of object is only found in some of my reports and that's why I face this problem only with some of the reports and not all of them.
The most common reason this happens is that not all the variables you use in the report are filled. So make sure of that. Otherwise you should get an error on the object you use. Do you get an error on exporting?
Looking for a component, dll, etc, for OCR for a VB.NET program. Using VS PRO 2008.
The source is a bunch of small png images, and I am just getting a price out of them. Very simple.
Tried tessnet2, but could not get png to work. Don't mind commercial, but not too expensive - maybe about $100. Want something simple to use and preferably with support if needed. This is for a commercial application.
Thank you!
Microsoft Office 2003 onwards (Or Word 2003+) comes with something called Microsoft Office Document Imaging (MODI) Its a COM component you can use to perform ocr.
See this:

And I also bumped into this:
http://weblogs.asp.net/jgalloway/archive/2006/10/01/Free-OCR-software_3F00_-You-may-already-have-it_2E002E002E00_.aspx
The downside of course would be needing office installed I think.
Got tessnet2 to work with png. png was not working because of the transparent background. Made a second image with a background color contrasting the text color, and drew the original image on top of that. The second image ocr'd perfectly.
Would still be interested in a commercial ocr not too expensive, but this works now.
Thank you for your replies!
I just installed Visual Basic 2010, went through some tutorials on how to display files, but can't find any material on how to select and embed existing PDF files into a form. Any suggestions or pointers in the right direction would be great, thanks!
Just embed a browser control in your form and navigate that to the PDF file. That should do the trick.
There aren't too many out of the box controls for that. Anyway, this guide might be helpful:

We make a GUI control that can load a bunch of image formats, and an add-on to turn PDF pages into images. The GUI control (ImageViewer) is part of our free SDK (DotImage Photo) and you can learn about the add-on here: http://www.atalasoft.com/products/dotimage/pdf-reader
