In Mac OS X, possibly the most convoluted configuration issue is printers that handle different or abnormal page sizes.
I own an Epson 2200 and an R200 (actually my R200 just died, and I'll be throwing it out but that's beside the point.) Both of these printers support borderless printing (and another mode called "minimize margins") as well as roll paper printing. However, after installing the printers, and going through every option in the Page Setup and Print dialogs, it looks like those features are not available in Mac OS X 10.4.
Well those features are available, they just aren't enabled by default. Apparently Mac OS X handles printers in a way that doesn't make it easy to change things like roll paper additions or differing hardware margins in a single printer. You'd think that would be handled just fine in the paper settings from the Page Setup dialog, but it isn't. It's possible this shortcoming is actually Epson's fault for how they implemented support for these features in their drivers, but no matter who is to blame, the configuration isn't obvious. You have to basically setup a different printer on the computer for each of these features that affects the paper margins and paths. So for example, instead of just having the R200 listed as an available printer, you'll have the R200 and the R200 "borderless" and the R200 "Roll Paper" etc. Of course, they are all the same printer, but to your Mac they all look like different printers with different capabilities and will be listed as different printers in your print dialog.
To get access to all these wonderful features, just follow these easy instructions:
You need to open the Printer Browser window. There are two ways to get to the Printer Browser:
Go under the Utilities folder under Applications and launch the Printer Setup Utility. Click the Add printer icon.
Either one of those steps bring up the Printer Browser:
At this point, your current Epson printer should show up in the Printer Browser. Now click More Printers...
In the drop down dialog sheet that appears click on the pop up menu at the top and select "Epson USB" (or "Epson FireWire" if you are using a printer with a FireWire connection like the 2200.) It takes a while sometimes for these dialogs to update as they are scanning the USB busses as well as searching every known printer driver installed on your computer.
At that point your printer should appear with the different features listed in the Page Setup pop up menu. For example, if you now select your Epson 2200 printer, under the Page Setup menu, you should see an entry for your 2200 with borderless printing, another entry for roll printing, etc.
Add any of the ones you want to have available or all of them. Then when printing, you have to choose which printer to use based on what features you want (they will all appear in your printer dialog as separate printers, and you can even designate one of them to be your default printer.) Oh and make sure you select them in both your Page Setup dialogs as well as your Print dialogs if you need features (such as special paper sizes) available. The Page Setup dialog will let you choose the larger paper types supported by roll printing, etc.
So there you go, now you can take full advantage of your expanded printer capabilities.
