Printer4Lazarus package
|
|
=======================
|
|
|
|
This package adds some components.
|
|
TPrinterSetupDialog - for update properties of selected printer
|
|
TPrintDialog - for select and/or update an printer before printing
|
|
TPageSetupDialog - to select margins (currently only under Windows)
|
|
|
|
Win32:
|
|
Native implementation
|
|
|
|
Notes:
|
|
1. TPrinter.CanRenderCopies return information if printer driver is able to print more then one copy at once.
|
|
Not all printers drivers support that feature (n that case programmer should print document requested times)
|
|
|
|
2. TPrintDialog.Options indicate which controls should be visible in dialog.
|
|
TPrintDialog.PrintToFile indicate that output will be redirected to file.
|
|
|
|
3. Known Issue: After adjusting resolution using Printer.AdvancedProperties. The DevMode structure
|
|
shows the change correcly, but getting the value through Printer.XDPI the value is the old one.
|
|
However after using the PrintSetup dialog, it returns the correct value. Other changes like
|
|
the selected paper are correctly modified after AdvancedProperties, ... (?).

Linux and Mac OS X (gtk):
|
|
Yous must install CUPS and libcups v1.1.19 or more.
|
|
|
|
Mac OS X (Carbon):

Uses CUPS by default. You can use native implementation by adding compiler switch -dNativePrint.
