Printer Setup

First, you'll need CUPS. If you have a Hewlett-Packard printer (HP brand), add the HPLIP package.

# apk add cups cups-libs cups-pdf cups-client cups-filters hplip

Tip: As with all installation processes, Alpine's package management can guide you on the need to pull various packages from other repositories (e.g.@testing) other than the enabled main or edge repositories throughout this wiki page, as long as these other repos have been pinned. For example, for Alpine version 3.7.0 on x86_64 systems, apk would have then guided you to substitute in cups-pdf@testing and hplip@testing.

Then go to http://localhost:631 with your web browser and follow the steps to "Add Printer". It will ask you to log in to add a printer. Log in as root, then finish the steps. Once you're done, you should be able to print.

If that doesn't work, you may also need to add HPLIP's dependencies separately. There are currently no packages for CUPS DDK, hp-setup or foomatic.

# apk add libusb ghostscript qt py-qt python3 py-reportlab libjpeg libjpeg-turbo net-snmp

mdev hacks for USB printers

By default USB printer with mdev would have ownership root:root and permission 0660. As cupsd would try to open a libusb-based printer as lp user, it won't have permission to use the device in /dev/bus/usb.

First let's get some info about our USB printer.

# lsusb | grep Printer
Bus 002 Device 011: ID 04b8:0007 Seiko Epson Corp. Printer

Now use 002 and 011 for next query.

# udevadm info -p $(udevadm info -q path -n /dev/bus/usb/002/011)
P: /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.1
N: bus/usb/002/011
E: BUSNUM=002
E: DEVNAME=/dev/bus/usb/002/011
E: DEVNUM=011
E: DEVPATH=/devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.1
E: DEVTYPE=usb_device
E: DRIVER=usb
E: MAJOR=189
E: MINOR=138
E: PRODUCT=4b8/7/100
E: SUBSYSTEM=usb
E: TYPE=0/0/0

What is important for us is 'PRODUCT'.

# cat >> /etc/mdev.conf <<EOF
SUBSYSTEM=usb;PRODUCT=4b8/7/100;.* root:lp 660 */lib/mdev/usbdev
EOF

Unplug USB cable and plug again, now USB printer device in /dev/bus/usb/ will have valid ownership and permissions.

# ls -l /dev/bus/usb/002/011
crw-rw---- 1 root lp 189, 138 Apr 14 21:19 /dev/bus/usb/002/011

CUPS will be able now to use libusb to discover local USB printer.

Desktop Environment

Additionally, in a desktop environment you could proceed as follows.

Check whether root and the user's username (yourusername) are already members of the lp and lpadmin groups. Note: yourusername can be added to the lpadmin group if he/she will administer the CUPS system.

$ id root
uid=0(root) gid=0(root) groups=0(root),0(root),1(bin),2(daemon),3(sys),4(adm),6(disk),10(wheel),11(floppy),20(dialout),26(tape),27(video)
$ id yourusername
uid=1000(yourusername) gid=1000(yourusername) groups=1000(yourusername),6(disk),10(wheel),18(audio),19(cdrom),20(dialout),27(video),100(users),1001(plugdev)

If not, add them:

$ sudo adduser root lp
$ sudo adduser root lpadmin
$ sudo adduser yourusername lp
$ sudo adduser yourusername lpadmin

Start CUPS (cupsd) and make it persist between boots; then reboot:

$ sudo rc-service cupsd start
$ sudo rc-update add cupsd
$ sudo reboot

Credit to ArchWiki's excellent CUPS page for guidance with the following basic steps. Locate your printer

With your printer connected and powered on, determine the URI for your printer. Depending on whether the connection is via usb or parallel ports, the URI will carry a usb:// or parallel:/ prefix.

$ lpinfo -v #
network lpd
network socket
network beh
file cups-brf:/
direct usb://HP/LaserJet%202200
network ipp
network ipps
network https
network http
direct hp

In the example above, the URI is usb://HP/LaserJet%202200

Find a .ppd or .ppd.gz driver.

If your printer supports IPP Everywhere --most recent models do-- see the driverless command in cups-filters:

$ driverless ipp_uri > printer.ppd

or just pass -m everywhere to lpadmin.}}

Otherwise, you could list all the drivers available by running lpinfo -m and then searching through the results to find a .ppd or .ppd.gz specific to your printer. A quick solution is to use the --make-and-model flag and the grep function in order to filter the results by plugging in your printer's make, model and series in this fashion:

$ lpinfo --make-and-model "make_and_model_names" -m | grep -i printer_series

Tip:

• Search for the term HP to find instances of Hewlett-Packard.
• You do not need to state the printer_series in whole if at all e.g. 2200 may be preferable to searching for 2200M, etc.

For example, type:

$ lpinfo --make-and-model "HP LaserJet" -m | grep -i 2200

Out of the results obtained, you might select the following .ppd driver:

drv:///hp/hpcups.drv/hp-laserjet_2200_series.ppd

If required, further drivers can be obtained by installing gutenprint, and running the lpinfo search again. These may not specify .ppd names.

$ sudo apk add gutenprint gutenprint-doc

Configure a queue

Create a queue using a queue_name of your choice. Your selected printer's name is an obvious choice, but do not employ spaces. You will also need to be root or use sudo instead, and you will also need to plug in the URI and the .ppd driver:

# lpadmin -p queue_name -E -v "uri" -m driver

With this example, you could set as follows, but there are other solutions.

# lpadmin -p HP_LaserJet_2200 -E -v "usb://HP/LaserJet%202200" -m drv:///hp/hpcups.drv/hp-laserjet_2200-pcl3.ppd

This printer queue could be set as default:

# lpoptions -d HP_LaserJet_2200

Printer settings can typically be set in your GUI application's Print menu or by examining the CUPS lpoptions page. If you have a single queue, the setting options available (such as page type, duplex, etc.) for your queue can simply be listed by using the -l flag. Asterisks(*) indicate current settings:

# lpoptions -l
PageSize/Media Size: Card3x5 Hagaki Photo4x6 A6 Photo5x7 Card5x8 Oufuku A5 B5 JB5 Executive 16k Letter *A4 ExecutiveJIS FLSA Legal EnvA2 EnvC6 EnvChou4 EnvMonarch EnvDL Env10 EnvChou3 EnvC5 EnvB5 Custom.WIDTHxHEIGHT

If there is only one queue, options can be set by simply using -o flags for each setting:

# lpoptions -o PageSize=Legal -o Duplex=DuplexNoTumble
