Subject:
Slow Printing from Macintosh
From:
Technical Services Dept., GTS Division
Classification:
SYMPTOM
Depending on network conditions, printing from a Macintosh is very slow.
This symptom occurs in the following machines:
Model K-P1 (Kir-P), Model A-C2 (Adonis-C2), Model J-P1 (Model J).
This occurs in the following conditions:
- Macintosh with PowerPC G3 or G4 processor
- Network: Apple Talk (Ether Talk)
- Network Speed: 100Mbps (100Base fixed)
CAUSE
When the data is transferred at 100Mbps, depending on network conditions, the controller
ASIC is not able to receive all data packets and a retry procedure occurs. As a result, print
jobs from a Macintosh take a long time to print out.
SOLUTION
Please also see the flow chart attached on the last page.
1) Check what type of hub the customer is using.
If the customer is using a dual speed (10M/100Mbps) hub, go to step 2.
If the customer is using a 100Base fixed (100Mbps only) hub, go to step 3.
2) For the customer using a dual speed hub:
Set the network (ethernet) speed of the machine to 10Mbps.
The default setting of the machine is "Auto." This setting can be changed in the
"Network Setup" in the user mode "Host Interface" ("Interface Settings" in the "System
Settings" for the Model A-C2).
End of procedure for the customer using a dual speed hub.
