Suggestion for new version. Improve printing
« on: August 23, 2021, 02:11:34 am »

Hi everyone.
I've been using QB64 in an accounting and warehouse management program for several years, and I print a lot of listings and invoices.
I think a lot of Qb64 users are currently focused on games and graphics, but I find it to be a great language for developing business applications with databases and reports. The versatility with respect to QB45 (which was the language I used in my programs) is enormous.
One limitation that I consider to be very great and would help a lot in the development of management programs is the printing options. Currently, to print an invoice or a list, I have to create a graphic page, load a template in JPG, fill it with the data and images of the company logo, etc. and then execute _PRINTIMAGE with each of the pages. The file that it sends to the printer, being graphic, is quite large and makes it not immediate, especially if what I want is to convert it into PDF with PDFCreator or some other similar program. A 20 page listing (very common) can take 30 minutes to generate, which is not operational.
Likewise, since there are 20 independent pages (although it is the same document) if I have the double-sided printer configured, it does not print double-sided because that only does it if it is a single document. I do not know if I explain myself very well.
A solution for large listings is the one Pete pointed me out, creating a text file and using WordPad in the background. With that method, converting the same 20-page listing to PDF takes 2-3 seconds. The problem that I see using an external program is that I do not trust that Windows 11, 12, 13 or 14 (to name them) removes WorPad, calls it something else or what do I know what Windows developers can do. Also with this method I cannot print images as it happens in the invoices in which the template and the logo are a JPG.
Anyway, after this roll, I think it would be interesting to include in the following versions another way of sending data to the printer, other than through images. I already know that LPRINT exists but it does not allow changing sizes or fonts, or anything like that.
Greetings

If you're using Windows, Zach's printing routines might be what you are looking for: https://www.qb64.org/forum/index.php?topic=4102.msg134503#msg134503

Thanks FellippeHeitor
I will try to understand how it works to see how I can adapt it to my listings.
My fear is: if windows changes internally in future versions, will this still work?
JPG files cannot be included here to be able to use logos or invoice formats?

I don't think you should fear that so strongly.

Well seeing how windows doesn't work now, without convoluted workarounds, I think I'm with Fellippe.
Granted after becoming radioactive I only have a half-life!
