Printing in Linux / Escape for Linux?

We are just about to make a "giant" step from MSDOS 6.22 to Linux (yes, DOS users still exist) and currently use the Escape library for printing to PCL printers. However, Escape shut down their support long time ago, and this product is to our knowledge not available for Linux. Can anyone advice how to make a Clipper program make "neat" printouts under Linux? We will be going for either CLIP or Harbor (undecided). Is there an Escape-library lookalike available for Linux to handle this, or any other solution? Thank you in advance for any insight. We are greatly looking forwards to catching up with the rest of the world and finally get rid of DOS...

To print ASCII text, I was using Epson LQ codes until a time then I switch all our applications to HP LJ3 codes at a time without any layout problem. Hope this will help you ... if you don't use graphics codes.

You can configure Linux any way you want, but, it would be atypical to hardcode your application to send printer-specific codes to a printer in this manner. More typically, most popular Linux applications generate postscript output. Linux is then configured to interpret this and translate it to suit your specific device using a filter such as Ghostscript. For Winprinters, one Ghostscript driver that *may* work is called "GDI". For more information, Linux-specific groups should be consulted. linuxprinting.org has been a helpful resource to me. A couple of years ago, I had to recompile the Ghostscript for Slackware Linux 8.1 to include the GDI driver for my Samsung ML-4500 (winprinter). Since then, I've tried some other RPM based distros and they've all auto-magically detected my printer and configured CUPS and associated printing support software. There are a variety of options for generating postscript from your application. Look for "typesetting" and you'll find stuff like Tex and Lout that make producing postscript or device independent formats simpler. Postscript libraries for Clipper exist, and should port easily, but, I have no specific experience.
