Cups has now suddenly started hanging for 10-15 seconds on each print. Googling suggests cups is sending a SNMP request which these devices don't support. The only solution is to<br> amend the PPD file. However I'm printing pcl using the raw model, so no PPD file. Server is Centos 6 and not been patched recently. Another patched server has the same issue. Any ideas ?
