I thought I would ask what approach(es) people are taking with printing under FiveLinux.

A few years ago, before I discovered the wonderful world of xHarbour / FiveLinux I played around with FlagShip (also xBase dialect on Linux). I wrote a series of functions then to create postscript files direct from my application. That involved quite a few public variables. In an xHarbour / FiveLinux environment you would write a class and use class properties and methods.

I've started to do that, but before I got too far thought I should find out what others are doing.

Also if others are interested in a postscript class (would also work in a Windows environment) let me know.

I would be interested to hear from you.

Hi Doug

I did my linux compiler without Fivelinux.

screen text mode only, not GUI

function main()
local cFilePrint := "report.prn"

set console off
set printer on
set printer to (cFilePrint)
?"Hello xProgrammer"
?"I'm Fafi"
?"Thank's for help"
set console on
set printer off
__run("lpr "+cFilePrint)
return nil

Hi Fafi

That's good but if you want more control over your printer (like graphics, controlling fonts) you'll need a more sophisticated approach.

If you have a postscript printer you might want something like this in cFilePrint:

I need to output some pretty fancy forms amongst other things. I am hiding some of the ways postscript works that run counter to how we expect them in xBase such as:

postscript measures up from the bottom of the page

in postscript you put data on the stack which is then pulled off by operators as required. In xBase we would expect something like:
whereas in postscript you have:
Of course an xBase class can hide that so you can call:
which would add the corresponding moveto command to the postscript document being built.

In fact rather than use moveto and show you can define an "atsay" method so that you can code:
Interestingly you don't have to directly generate a moveto and a show, because you can define functions in postscript such as this:
Also rather than have to work vertically from the bottom by setting a page height and top margin in the class instance you can work from the top down (in xBase), the object doing the coordinate conversions for you.

That's where I'm currently headed.

Hi Doug !

I have some GUI libs based on GTK+ and libgnomeprint for printing.
Please your email address, I will send you the example
