Using Lightroom for Windows 8.1 with Epson Stylus Photo R3000 printer. From PRINT section, if I click either "Page Setup" or "Printer" I get the Epson printer dialog box, drill down, change settings- so far so good. When I'm finished with the settings and close the dialog box (hit OK) the print job starts immediately; I never get a chance to hit the Lightroom "Print" button. Question: does this bypass any Lightroom processing or control of the print job?
Clicking the Printer button will behave like that because is just allowing you to make a last-minute check of your settings. But clicking the Page Setup button should not activate the printing process. I don't know how to tell you to correct this.
Even if I just click the Printer button to verify my settings I should then return to Lightroom, and then click Print to start the job. This does not happen, the job starts as soon as I close the properties dialog box. Again, is any Lightroom processing or control being bypassed because of this?
No. If the printer settings are right then your print should be just fine.
