Main trade-off
HP Smart Tank 5101
Manual duplex and 30-sheet output. A loaded input tray is not an unattended-job allowance.
Head-to-head
Choose Smart Tank 6001 for regular two-sided PDFs or longer plain-paper batches. It prints both sides automatically and holds 100 finished sheets against 5101’s 30. Both are listed at 12 black ISO ppm, so the main upgrade is less paper handling. Smart Tank 5101 remains reasonable for short one-sided work if its current offer is better. Neither has a document feeder, so a physical stack still needs individual flatbed placement.
Before you choose
A parent can send a supported two-sided PDF to the 6001 and avoid the specific stop to turn the stack. The 5101 requires that return, so the printer competes for attention while dinner, homework or another task is underway. Both list 12 black ISO pages per minute. That makes this a handling decision rather than a claim that each black page prints faster. The job still needs correct paper, duplex settings and space for the finished sheets.
What this is based on
A parent alternating household tasks plus a digital two-sided packet crossed with equal black ISO speed and different duplex handling. No guaranteed time saving or unattended reliability is inferred.

Main trade-off
No document feeder or Ethernet. Physical packets still need repeated handling.


HP Smart Tank 5101 vs 6001 for school PDFs, interrupted evenings and family paperwork. See what automatic duplex and a larger output tray actually change.
These flatbed Smart Tank models serve the same shared home and student buyer. Their equal black ISO speed can make the upgrade look minor, while the physical paper routine changes substantially for longer and two-sided jobs.
Winner by situation
6001 removes the manual paper turn.
Only 6001’s output rating covers the total.
Compare current offers. Black ISO speed is equal.

An illustrative 80-sheet plain-paper job fits both input ratings. It exceeds the 5101’s 30-sheet output allowance and therefore needs collection during the job. It fits within the 6001’s 100-sheet output rating when that tray starts empty. The difference remains useful even if every page is one-sided. These ratings describe supported plain paper, not a guarantee for curled, heavy or photo sheets. Remove the finished batch before the next family member sends work.
A longer one-sided household batch plus a shared printer crossed with input versus output capacity. Eighty physical sheets are within both input ratings but only one output rating. No exact collection timing is assumed.
If the task begins with a signed school packet on paper rather than a PDF, both models require placing individual originals on the flatbed. The 6001’s automatic duplex output does not add a feeder or automatically capture the backs. A household that mainly downloads and prints benefits differently from one that repeatedly scans incoming forms. Check which direction the paper travels in your week before choosing the higher model. A feeder-equipped alternative may address the actual nuisance more directly.
Downloaded school work versus incoming signed forms crossed with shared flatbed-only scanning and the distinction between input and output duplex. The recommendation depends on the task origin.

Meaningful differences
| What changes | HP Smart Tank 5101 | HP Smart Tank 6001 | Why it matters |
|---|---|---|---|
| Two-sided PDF | Manual duplex. | Automatic duplex on supported paper. | The 6001 can remove a mid-job visit rather than merely raise print speed. |
| Input and output | 100 input, 30 output sheets. | 150 input, 100 output sheets. | Output grows by 70 sheets, which can matter more than the 50-sheet input increase. |
| Listed speed | 12 black, 5 color ISO ppm. | 12 black, 7 color ISO ppm. | The black throughput headline is unchanged. Mixed jobs need their own timing. |
| Physical originals | Flatbed without feeder. | Flatbed without feeder. | Incoming forms remain a different job from printing downloaded files. |
