That's not the problem. The problem is that it's getting hard to find Laser printers that print ascii data streams. Recent HP printers no longer work with character streams. So we have to intercept the print stream and "render" to graphics. Including all the character escapes that make things bigger and bold and so forth. That part is all working fine with the Windows GDI. It seems what I need to do is make a postscript rendering engine for it to work under Linux. Which looks possible, but I'm open to other ideas.

Would it be possible to run the DOS software in a virtual machine under linux?

[SLUG] How to do a Custom Print Processor in Linux ?
Hi all, Background for this is that a client has a dBaseIV DOS accounting system that they will upgrade after the Senior Partner retires. Which is a decade or more away. Printing from DOS is the not negotiable part. For a few years, I've run a server on a Windows machine that intercepts LPT1: data and sends it to a TCP/IP port where I have a server process that then renders the text output to graphics (Windows GDI) under Windows and the output prints. Its all good until electrical contractors come and disconnect cables from the hub, and then the network goes, and it all breaks and users complain. This problem only occurs in XP, not on Windows 2000, but the W2K is disappearing. Now I want to move the rendering of text files to a Linux server (some stable ones exist here) and hoping to do the same in Linux. Anybody know how to drive CUPS from Python and do GDI level control ? -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
