Hi, mh, maybe i misunderstand you, but normally cups find out what is send to them, and will convert it automatically to ps, if your ppd file is correct and your /etc/cups/printers.conf also. i checked my ppd old and new, i have only changed a little to get rid of some warning messages. and, i changed ps version from 2 to 3 inside ppd (but one of my 2 printers is not able to understand 3) but with 3 this ps2 printer prints better (or at all, i do not remember) for sure, this printer is not able to understand 3, but maybe cups makes some other converts so that it worked fine. (to get these old machines printing has cost me several nights.... for the newer cups, before it was working out of the box) ========== here are some parats for one printer of my 2 printers.conf files, old, and new, (for a postscript only printer) as you can see, you must change some settings to get it to print with new cups versions. see especially the "Filter" and "DeviceURI" line. # Printer configuration file for CUPS v1.4.6 # DO NOT EDIT THIS FILE WHEN CUPSD IS RUNNING <Printer qms_6100_oben> Info QMS magicolor 6100 MakeModel QMS magicolor 6100 DeviceURI socket://192.168.0.11:35 State Idle StateTime 1530034931 Type 8401100 Filter application/vnd.cups-raw 0 - Filter application/vnd.cups-command 0 commandtops Filter application/vnd.cups-postscript 0 - Accepting Yes Shared Yes JobSheets none none QuotaPeriod 0 PageLimit 0 KLimit 0 OpPolicy default ErrorPolicy stop-printer Attribute marker-colors none,\#00FFFF,#FF00FF,#FFFF00,#000000 Attribute marker-levels -1,-1,-1,-1,-1 Attribute marker-names ,,,, Attribute marker-types toner,toner,toner,toner,fuserOil Attribute marker-change-time 1530034931 </Printer> # Printer configuration file for CUPS v2.3b4 # DO NOT EDIT THIS FILE WHEN CUPSD IS RUNNING <DefaultPrinter qms_6100_oben> PrinterId 4 UUID urn:uuid:88d769c9-d013-3c4f-7560-c690bd82a911 Info QMS magicolor 6110 MakeModel magicolor 6110 DeviceURI socket://192.168.0.11:35/?version=1.1 State Idle StateTime 1530007972 ConfigTime 1502986825 Type 8401100 Accepting Yes Shared No JobSheets none none QuotaPeriod 0 PageLimit 0 KLimit 0 OpPolicy default ErrorPolicy stop-printer Attribute marker-colors none,\#00FFFF,#FF00FF,#FFFF00,#000000 Attribute marker-levels -1,-1,-1,-1,-1 Attribute marker-names ,,,, Attribute marker-types toner,toner,toner,toner,fuser-oil Attribute marker-change-time 1530007972 </DefaultPrinter> hope this helps you. simoN -- www.becherer.de -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
