Is it necessary to add an HP printer to CUPS using the hplip URI?

I recently setup a CUPS print server (Ubuntu server 12.04) and I having trouble with performance of a HP Color LaserJet Printer CP3505n. The printer pauses for about a second between printing each page, which is annoying when there is a lot of printing to be done. This doesn't happen when the printer is installed directly to a Windows client.

In an attempt to fix this I have setup the printer a couple different ways. I decided not to do a Samba share since this wiki said IPP is preferred.

First Method

• Added to HP LaserJet to CUPS as a Discovered Network Printer, and selected HP Color LaserJet cp3505 hpijs pcl3, 3.12.2 (en) driver. I did not use a hplip URI.

Second Method (hplip URI)

• I thought adding hplip to the mix might improve the performance, so I added the printer like this:

  • Ran hp-setup -m 192.168.2.60,

  • prompted to select driver

    Selected HP Color LaserJet cp3505 hpijs pcl3, 3.12.2 (en)

  • Used hplip to generate a URI: hp-makeuri 192.168.2.60

  • Then added the printer to CUPS as a Local Printer: HP Printer (HPLIP), and entered: hp:/net/HP_Color_LaserJet_CP3505?ip=192.168.2.60.

Either method I use I am able to share the printer on the network by adding a printer as http://192.168.2.2:631/printers/HP_LASER-TERRAC.

• Does it make a difference which way the printer is added cups?

  If so, and I install the printer with the hp URI, can I still change the driver using the CUPS web interface? I have been trying out different drivers to try and improve performance, and the cups interface is the easiest way to change them.

  Thanks in advance.
