So, I've been tasked with making several of our in-house applications print using the Zebra P4T printers. Communicating with them has been rather pain free.
However, I need a scalable font for part of it. I read the manual, and boy that sounds easy. Downloading a font is easy. But I've yet to find a way to create a scalable font. Zebra tech support has been less than helpful, going so far as to tell me that it cannot be done, even though their documentation says it can.
I've used the Zebra Font Downloader, and can create all sorts of .CPF files to push to the printer, but can't figure out how to make a .CSF (scalable) one. There doesn't seem to be an option to make a font scalable before you download it.
This brings me here, as I'm about to pull out my already grey hair.
Found another solution, since I couldn't install the third-party driver as someone else suggested.
Instead, we setup a virtual machine running Windows XP, and installed Zebra's 'Label Designer' software. Then I used that to make scalable fonts. From there it was easy to transfer said fonts to a network drive, and send them to the printers.

I want to write a web app that can process a users presentation which when submitted, gets sent to their local system printers - one part of the order will go to B&W laser printer and another part goes to another printer for another process.
Ideally, this will be able to run on any of the major systems - Linux, OSX or Windows.
It could be a packaged Chrome or Firefox app or extension, but I can't tell if there is sufficient access to the system printers. (I can see all the printers available to my current chrome installation - but are they available to an extension?). I can't see the code in any demos or libraries.
I've seen reference to NPAPI, but I can't tell if that's what I need either - if so would I need to write an app for each of the major platforms or each kind of printer?
In Firefox it is possible to print from an extension. Using only javascript, that is (you're free to mess about with C++ if you like).
Extensions are essentially the browser: Everything the browser can do, an extension can, too.
There is however not much documentation about using the printer. To be precise, there is none that I'm aware of. However, the browser is open source, and the UI is mostly Javascript, so you can just read the code.
printUtils.js would be a good starting point to check out how this might work. Also there is a component implementing nsIPrinterEnumerator. See the firefox-addon info section for a collection of "Getting started" and documentation resources about add-on development in general.
I don't think the Chrome extension API provides ways to control printing the way you'd need.
The NPAPI plugin API does not provide enough control over printing. You just basically get a buffer to draw into, but no way to control printing setting or initiate printing yourself. You could cheat of course, and have your plugin directly print something via OS bypassing the browser, like e.g. those PDF readers do. However, it should be noted that NPAPI plugins are the past... Don't develop new ones, if possible.
I've been scouring the SO board and google and can't find any really good recommendations for this. I'm building a Twilio application and the text-to-speech (TTS) engine is way bad. Plus, it's a pain in the ass to test since I have to deploy every time. Is there a significantly better resource out there that could render to a WAV or MP3 file so I can save and use that instead? Maybe there's a great API for this somewhere. I just want to avoid recording 200 MP3 files myself, would rather have this generated programatically...
Things I've seen and rejected:

http://www2.research.att.com/~ttsweb/tts/demo.php
http://www.naturalreaders.com/index.htm
http://www.panopreter.com/index.php (on the basis of crappy website)
Thinking of paying for this, but not sure yet: https://ondemand.neospeech.com/
Obviously I'm new to this, if I'm missing something obvious, please point it out...
I am not sure if you have access to a mac computer or not. Mac has pretty advanced tts built into the operating system. Apple spent a lot of money on top engineers to research it. It can easily be controlled and even automated from the command prompt. It also has quite a few built in voices to choose from. That is what I used on a recent phone system I put up. But I realize that this is not an option if you don't have a mac.
Another one you might want to check into is http://cepstral.com/ they have very realistic voices. I think they used to be open source but they are no longer and now you need to pay licensing fees. They are very commonly used for high end commercial applications. And are not so much geared towards the home user that wants their article read to them.
I like the YAKiToMe! website the best. It's free and the voices are top quality. In case you're still worried about giving them your email, they've never spammed me in many years of use and I never got onto any spam lists after signing up with them, so I doubt they sold my email. Anyway, the service is great and has lots of features for turning electronic text into audio files in different languages.
As for the API you're looking for, YAKiToMe! has a well-documented API and it's free to use. You have to register with the site to use it, but that's because it lets you customize pronunciation and voice selection, so it needs to differentiate you from other users.
I need to add printing capabilities to an app and I have been looking around for information about printing. Logical/physical sizes, dpi, font scaling, etc, lots to digest since I never programmed printing into any app before.
Are there any sites that would offer a primer on the topics of page sizes, margins and all the other elements required to understand printing on Windows? I've been looking around for a while but what I find is either cryptic or years old...
I've been playing around with TPrinter, but I would like to build solid printing functionalities and understand what I'm doing better.
Using a report solution is not an option, even though I'm sure it would provide better results much sooner.
Two links to get you started:
Printing with TPrinter
Printing via the TPrinter Canvas
I think that you are looking too lowlevel.
Try looking at the build reporting tools (Rave or whatever is in your product).
Personally i am using a product called Report Builder from Digital Metaphors.
But if you want to do the lowlevel stuff lot og good information can be found at efg's computer lab - printing
Well, I have done things a variety of ways in the past, including the "hard way" with TPrinter. In fact, I recently had to do that again to run a special inventory label printer.
On the other hand, sometimes you are better off taking work others have done and using it for your benefit. I agree that ReportSmith isn't so great, and also it's Delphi (and Windows) specific. Using Excel or Word has those limitations, plus the fact that the user has to actually have them installed.
One thing I have done to make printing easy for some simple applications is just to generate an HTML file and call the user's web browser, then they can print it. HTML tables can be created relatively easily for numerical data, and you can include photos, etc. as well. This works well for some applications, and works on every platform where a web browser is installed. The downside, of course, is that HTML isn't the most precise layout language.
The version of Delphi you´re using is important. A number of Delphis came with print engines like ReportSmith (ugh). Another option thinking laterally is to use MS Word as a print engine. I´ve hooked into instances of Word & Excel before & utilised their functionality. As to raw printing using TPrinter or the print method of TForm you´d have to be pretty desperate. I seem to recall the Pacheo / Texeira Delphi books coming with a pretty good overview so you might want to see if you can find a copy of that somewhere.
I'm building a new web-based product. The problem is that many clients have specific printers to print specific documents. Just think reports,barcodes,invoices etc. All on a special printer with the right paper etc...
Usually when printing from the web you cannot make the software choose a printer or change the settings. However it's just that that I want to do.
I want to print without a dialog. And enter the printer + settings with my software
The only solution I know of now is the commercial version of acrobat that has some javascript printing support..
Does anyone know of any other alternatives ?
Thanks in advance !
small-medium business
No heavy installion but common stuff is ok
ie. flash/silverlight/acrobat/whatever is possible
I generate what is necessary for printing (PDF/Tiff etc)
Who are your customers -- enterprises or SOHO? Are you generating PDFs? Or, raw tiffs? If you are generating PDFs there is something called a JDF file where you can specify the print settings to your heart's content. The flip side is the device needs to be capable of understanding JDFs. You can then attach the JDF with the PDF as a mime package. If you are generating tiffs, I think there isn't much need of printer settings except for the correct device profile(s) to be installed.
Because of security reasons, you cannot control that from within the browser.
If I where in your shoes, I'd create a small program for my clients to install, registering a specific file extension to this program and creating files in this format on the website, and have the program do the printing for me.
Your easy choices are either PDF or Microsoft's Reporting/Report Viewer
We are making a lab instrument using an ARM9/RTOS system. The client has asked about printing simple reports from the ARM9 system. In this case, we have USB Host support in the RTOS. I'm thinking about printing bitmaps in generic PCL, hoping that will cover the widest range of printers. Is there a better way to approach this? I'm assuming the RTOS does not have printer drivers, and I don't want to support a lot of printers.
We also support USB device mode on our system, so you could plug in a photo printer, and our device would appear to be a USB stick. So that would work, but it's a bit clunky. This will be a C/C++ embedded system
Pretending to be a digital camera and interfacing with a PictBridge printer actually sounds pretty clever. It would remove the need to deal with different printer drivers, and if my understanding of the technology is correct, you could even control the operation of the printer right from your device.
On the other hand, as someone who has used a fair number of computerized lab instruments (oscilloscopes etc.) I find the ability to save screenshots from an ethernet/web interface to be much more useful. Print is dead.
Have you looked at what all the scope vendors are doing? They all have print options (I think) and I don't know what they are doing to solve this problem.
Last time I was involved with something like this, we used serial ports to talk to HP printers using PCL. That backfired as everyone quickly stopped making serial printers!
PostScript is natively supported by most printers, so you could just send it over the wire, but it would be a lot more cumbersome than straight ASCII. There are libraries, but they're bulky.
Since your device can appear to be a USB stick, a simple solution would be to generate a report as a JPEG image and then have the printer open and print it. This way, the people who want paperless output can use the image as-is, and everyone else can print it.
If I understand you correctly, you could write a formatted text file and do a "print" command through Windows in the "usb stick" mode.
For a simple report, it would be best to stick to straight ASCII. If you need some graphics, PCL would be a good choice for B/W laser printers, but I'm not sure how universal it would be for the more common ink-jet printers.
Edit: the PCL Reference Manual is available as a PDF from HP.
