# Knowing Knoppix/Peripheral devices

# Printing

Knoppix has built-in support for
hundreds of popular printers. Parallel and USB connections are
supported. The best supported inkjet printers are HP and Epson. Many
Canon and a few Lexmark printers are also supported. On the laser front,
all greyscale Postscript and most greyscale Printer Control Language
(PCL) laser printers work.

However, some printers do not work with Knoppix. The printers that do
not work tend to be cheap Lexmark inkjet printers, and very low cost
colour laser printers. Colour laser printers work if they are fully
Postscript or PCL compatible. Unfortunately, very low cost colour laser
printers tend not to be compatible with either. They are therefore
completely incompatible with Knoppix.

To set up a printer connected by a USB
or parallel cable:

1.  Click the Knoppix icon in the Panel.
2.  Point to "Configure".
3.  Click "Configure printer(s)".\
4.  Wait for a moment while the KDE "Printing
    Manager" starts.
5.  Click "Add".\
6.  Click "Add Printer/Class...".
7.  The welcome screen of the "Add Printer" wizard will appear.
8.  Click Next.
9.  Select "Local printer", then click Next.\
10. Select the port that your printer is on. If your printer is
    connected to the computer\'s parallel port, select
    `Parallel Port #1 (/dev/lp0)`. If you have a USB printer, select
    `USB Printer #1 (/dev/usb/lp0)`. Click Next.\
11. Select the manufacturer and model of your printer. If you cannot
    find your exact printer model in the list, try the nearest
    available. For example the HP PSC 1200 driver works with the HP PSC
    1350, even though the HP PSC 1350 is not in the list. Click Next.\
12. This screen appears if Knoppix knows of more than one driver that
    can operate your printer. Usually the first or the recommended
    option will be fine. Click Next.\
13. Click the "Test" button to print a test page on your printer. After
    a short pause, your printer should start working.
14. When the test page has finished, click
    Next four times until you get to the "General Information" screen.
    Enter a short name for your printer, then click Next.\
15. Click Finish.\

    ```
16. The Printing Manager will be displayed again. You may now print from
    all the applications included in Knoppix. When you exit Knoppix, the
    printer setup will be lost. However, there is a way to save the
    setup. See the later section, "Finding permanence".

The test page paper size is US Letter by
default. If you are using A4 paper, the test page won\'t print all the
way to the bottom of the page. This is normal.

# Scanning

Knoppix has built-in support for some
scanners. Scanning in Knoppix is simple, if you are lucky enough to have
a fully compatible scanner. Scanner support is provided by a program
called "Scanner Access Is Now
Easy". If your scanner is
fully supported, you don\'t have to do any setup at all. To test a
scanner using Knoppix:

1.  Click K menu.
2.  Click Multimedia.
3.  Click XScanImage.
4.  If the scanner is detected, the device name will be shown at the top
    of the window. For example, if you have an Epson Perfection 1260
    USB, it will say `Plustek:/dev/usbscanner`.
5.  Assuming your scanner is detected, click "Preview Window".
6.  Click Acquire Preview.
7.  The image that the scanner sees will be shown.
8.  Lasso the area to be scanned using the mouse.
9.  Click "Scan".
10. The marked area will be scanned to an image file.
