Sysadmin Ramblings

We share our printers out from cups using samba. It was working great until a recent update broke the drivers from the windows/samba side. I decided to redo the configuration and use the cups driver for everything. Only problem was that after doing that I couldn’t add the third (optional) tray to our HP 2420DN. After reading a little about PPD and using cupsaddsmb to install the cups driver for windows clients, I came up with this hack job that appears to be working.

I added another tray InputSlot definition. By scouring other PPD’s and the cups wiki I found that Tray3 should be MediaPosition 1 on this printer. It is different for other models, on one model it was 7, go figure.
*InputSlot Tray3/Tray 3: "<</ManualFeed false /MediaPosition 1>> setpagedevice"
Then I change the InputSlot save
*?InputSlot: "
   save
     [(Tray3) (None) (Tray1) (Tray2)]
     statusdict /papertray get exec
     {get exec} stopped { pop pop (unknown) } if = flush
   restore
"
Then to be safe, I copied any references to Tray2.
*% Tray Constraints
*% ==================================================
*% Tray 3
*% ======
*UIConstraints: *PageSize Env10                         *InputSlot Tray3
...
*NonUIConstraints: *CustomPageSize True                 *InputSlot Tray3
*NonUIConstraints: *InputSlot Tray3                     *CustomPageSize True
...
*%------------------------------------------------------------
*UIConstraints: *MediaType Labels                       *InputSlot Tray3
*UIConstraints: *MediaType Transparency                 *InputSlot Tray3
*UIConstraints: *MediaType Card_Stock                   *InputSlot Tray3
*UIConstraints: *MediaType Envelope                     *InputSlot Tray3
After that, from the windows clients I could see Tray 3 in the Device Settings tab. And once I authenticated, I could actually change it to Legal paper, yay. One caveat to watch out for, I had to edit multiple ppd’s. I had to do this for the ppd in /etc/cups/ppd, the one in /etc/samba/drivers/W32X86/3 and /etc/samba/drivers/W32X86

Good luck.
